IMPLEMENTATION OF THE INVENTION

[24] Exemplary embodiments of the invention are described in detail below, examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings designate the same or similar elements. The implementation means described in the following exemplary embodiments of the invention do not represent all implementation means consistent with the disclosed invention. Rather, they are merely examples of systems and methods consistent with some aspects of the disclosed invention, as detailed in the appended claims.

[25] During the production process of consumables such as toner cartridges, etc., consumables such as toners, etc. may be replaced or updated, and the print quality and safety of printers largely depend on the consumables. To ensure the desired print quality, it is necessary to use various image formation control parameters. Generally, these image formation control parameters are stored in the consumable chips of consumables such as toner cartridges, etc. Printers communicate with the consumable chips to obtain the aforementioned image formation control parameters. However, communication between printers and consumable chips in existing technology is usually carried out through the exchange of encrypted code, which is easy to intercept for analysis and interference. After the consumables are installed on the printers, when the printers use these image formation control parameters, it may lead to a decrease in print quality or damage to the printer components.

[26] To solve the above-mentioned problem, in the embodiments of the present invention, the chip-side environment data and the printer-side environment data are detected, and the preset compensation value is encrypted and decrypted based on the above-mentioned environment data, which can avoid the technical problem that the preset compensation value of the image formation control parameter stored in the consumable chip in the existing technology is easily intercepted and interfered with, resulting in a decrease in the print output quality or even damage to the printer components. Therefore, data transmission is more secure, which guarantees the quality of printing and image formation and prevents damage to the printer components.

[27] In one embodiment of the present invention, an image forming apparatus may be adapted to perform image forming tasks such as generating, printing, receiving and transmitting image data; and examples of the image forming apparatus may include inkjet printers, laser printers, LED (light emitting diode) printers, copiers, scanners, all-in-one multifunction fax machines and multifunction peripherals (MFPs) that perform the above-mentioned functions in a single device. The image forming apparatus may include an image forming control unit and an image forming unit, wherein the image forming control unit may be adapted to control the entire image forming apparatus, and the image forming unit may be adapted to form images on conveyed paper under the control of the image forming control unit based on the image forming data, and a developer such as toners and the like stored in consumables.

[28] The main controller may be a system on a chip (SoC), which is a miniature system containing a plurality of system components, configured to control image-forming processing operations of the imaging device; for example, the operations may include processing such as performing linear correction, reducing noise, removing dead pixels, enhancing details, and the like on image data to improve image output quality. The imaging control unit may further be adapted to perform data transmission and reception operations, instruction transmission and reception operations, and processing operations related to controlling the portrait printing mechanism. For example, the imaging control unit may be adapted to perform operations including data transmission and reception, as well as printing mechanism control instructions, states, and the like via an interface unit (may include, but are not limited to, a USB port, a wired network port, a wireless network port, other interfaces, and/or the like).

[29] Fig. 1 illustrates a structural diagram of an image forming apparatus according to exemplary embodiments of the present invention. As shown in Fig. 1 as an example of the image forming apparatus, the image forming unit of the image forming apparatus may include a developer accommodating portion 11, a developing member 12, a developer transporting member 13, a photosensitive member 14, a transfer member 15, a fixing unit 5, and the like. After printing paper is conveyed in the paper feeding direction and sequentially passes through the toner feeding operation of the developer transporting member 13 and the developing operation of the developing member 12, the printing paper may reach a holding area between the photosensitive member 14 and the transfer member 15 for transfer printing, after which the printing paper may pass the fixing unit 5 for fixation, thereby completing the image forming operation. The developer accommodating portion 11 may be adapted to accommodate a developer. The developer may be a material including a color toner, a carbon toner, and the like; The photosensitive member 14 may include a photosensitive drum (for example, an organic photoconductor (OPC) drum), a charging roller, etc., wherein the charging roller may be adapted to charge the photosensitive drum; the developing member 12 may include a developing roller, etc., used to transport the developer to the photosensitive component 14; the developer transport member 13 may include such elements as a toner supply roller, etc., or may be replaced by such elements as a toner pushing screw, etc., used to deliver the developer to the developing device 12.

[30] In general, an image forming device may be removably installed with at least one consumable member. The image forming device shown in Fig. 1 is taken as an example; the image forming device may be removably installed with 4 consumable members (consumable member 1, consumable member 2, consumable member 3 and consumable member 4, respectively, shown in Fig. 1). The four consumable members may be adapted to provide the image forming device with developers of four colors, including black K, cyan C, magenta M and yellow Y. It is obvious that in other embodiments, the number of consumable members installed in the image forming device may be increased or decreased, for example, it may be 1, 6, etc., without limiting the disclosed invention thereby.

[31] The consumable chip may be, in particular, a circuit substrate mounted on a consumable element, wherein the circuit substrate may include a memory device and an electrical contact portion connected to the memory device. The electrical contact portion may be configured to be connected to an electrical contact portion on the side of the image forming device, wherein the electrical contact portion may be a conductive plane, a conductive probe, a conductive coil, etc.

[32] For a consumable element installed with a chip, an embodiment may be that the consumable element may contain only the developer-accommodating portion 11.

[33] An embodiment may be that the consumable member may be a separated structure. For example, the consumable member (1, 2, 3 or 4) may comprise a developing cartridge and a drum unit that are detachable from each other. The developing cartridge may comprise a housing, a developer accommodating portion 11, a developing member 12 and/or a developer transporting member 13; the drum unit may comprise a photosensitive member 14, including a photosensitive drum and a charging roller. The developer accommodating portion 11 may be located in the housing for accommodating the developer. The developer transporting member 13 may be adapted for transporting, and the developing member 12 may be adapted to transport the developer to the photosensitive drum, wherein the developer transporting member may be a toner supply roller or another component such as a toner pushing screw and the like.

[34] In an embodiment, the consumable element may be the aforementioned developing cartridge.

[35] In an embodiment, the consumable element may be the aforementioned drum assembly.

[36] In an embodiment, the consumable element may be an integrated structure. For example, the consumable element (1, 2, 3, or 4) may comprise a developer-accommodating portion 11, a developing element 12, a developer-transporting element 13, a light-sensitive element 14, and the like.

[37] It should be noted that the consumables mentioned in one embodiment may also be other components, parts and assemblies in the image forming device that are easily damaged and need to be replaced, such as paper boxes, which should also be included in the technical solution corresponding to the consumables protected by the present invention.

[38] Fig. 2 schematically illustrates an application scenario provided by exemplary embodiments of the present invention. As shown in Fig. 2, the consumable chip can perform calculations and first conversion processing on the detected data and transmit the data to the image formation control unit; and after receiving the above-mentioned data, the image formation control unit can perform the corresponding second conversion processing and calculation processing, so that the image formation device can perform printing and image formation according to the processed data.

[39] Option one

[40] Fig. 3 illustrates a flow chart of a method for controlling image formation provided by exemplary embodiments of the present invention. As shown in Fig. 3, the method in one embodiment of the present invention is applicable to an image forming device and a consumable chip. The image forming device may be detachably mounted with the consumable member, and the consumable member may be mounted with the consumable chip. The image forming device may include an image forming control unit and a first detection unit; and the chip may include a chip control unit. The method may comprise the following steps.

[41] In step 201, the first detection unit may detect first environmental data of the internal environment of the imaging device.

[42] In one embodiment, the first detection unit may comprise a sensor for detecting first environmental data of the internal environment of the imaging device in real time, where the internal environment may refer to the environment of the internal space surrounded by the housing of the imaging device. In particular, the first detection unit may be a temperature sensor and/or a humidity sensor. Accordingly, the first environmental data may include temperature data and/or humidity data.

[43] In step 202, the chip control unit may obtain second environmental data relating to the environment in which the consumable chip is currently located, determine a preset compensation value for an image formation control parameter corresponding to the second environmental data and a second preset intermediate transformation parameter corresponding to the second environmental data, perform transformation processing on the preset compensation value using a first transformation algorithm based on the second preset intermediate transformation parameter to obtain a first transformation parameter corresponding to the preset compensation value, and send the first transformation parameter to the image formation device.

[44] In one embodiment, a second detection unit, such as a sensor, may be adapted to monitor second environmental data in which the consumable chip is currently located in real time, wherein the second detection unit may be located on the consumable chip, in particular, located on the circuit substrate of the consumable chip or on the consumable chip and located on the periphery of the consumable chip, or located on the imaging device. When the consumable element is installed in the imaging device, the second detection unit may be located on the periphery of the consumable chip. The first environmental data and the second environmental data may be data at the same time, or there may be a short time interval between a time point corresponding to the first environmental data and a time point corresponding to the second environmental data. In particular, the time corresponding to the first environmental data and the second environmental data may be a time point corresponding to a certain time interval delayed after the imaging control unit sends a predetermined instruction to the consumable chip. The time interval can be set as needed and in accordance with the communication speed between the imaging device and the consumable chip, as well as the response speed of the consumable chip. The preset instruction may be, but is not limited to, a data read instruction, an instruction for notifying the consumable chip to prepare environmental data, or an instruction for collecting environmental data corresponding to second environmental data obtained by the consumable chip. The current environment may refer to the environment of the internal space contained within the housing of the consumable element mounted on the imaging device. In particular, the first detection unit may be a temperature sensor and/or a humidity sensor. Accordingly, the first environmental data may include temperature data and/or humidity data.

[45] The imaging control parameter may be a parameter configured to control imaging of the imaging device, including, but not limited to, a charging voltage, a transfer voltage, and a development voltage. Accordingly, the compensation value corresponding to the imaging control parameter may be a compensation parameter corresponding to the imaging control parameter matched with environmental data, as well as a calibration parameter, etc., so as to generate a color image, without limitation thereto.

[46] In the process of determining a preset compensation value of an image formation control parameter corresponding to the second environment data and a second preset intermediate transformation parameter corresponding to the second environment data by the above-mentioned chip control module, the chip control module may, in particular, first determine a preset compensation value based on the second environment data and a stored corresponding relationship between the environment data and the compensation values corresponding to the image formation control parameter, and determine a second preset intermediate transformation parameter based on the second environment data and the stored corresponding relationship between the environment data and the intermediate transformation parameters.

[47] It can be seen that the corresponding relationship between the environment data and the compensation values corresponding to the image formation control parameter, and the corresponding relationship between the environment data and the intermediate conversion parameters can be preset and stored in the consumable chip; in particular, it can be stored in the memory unit of the consumable chip or directly in the computer program included in the control unit of the chip, without being limited to what is specified in this document.

[48] The aforementioned second preset intermediate transformation parameter can be understood as an encryption key, the first transformation algorithm can be understood as an encryption algorithm, and the first transformation parameter corresponding to the preset compensation value can be an encrypted preset compensation value. The chip control unit can encrypt the preset compensation value based on the second preset intermediate transformation parameter through the first transformation algorithm to obtain the first transformation parameter corresponding to the preset compensation value, that is, the preset compensation value after encryption processing, and can send the first transformation parameter to the imaging device.

[49] In step 203, the imaging control unit may receive a first transformation parameter corresponding to a preset compensation value of the imaging control parameter sent by the consumable chip; determine a first preset intermediate transformation parameter corresponding to the first environment data; based on the first preset intermediate transformation parameter, perform transformation processing on the first transformation parameter using a preset second transformation algorithm to obtain a preset compensation value; and based on the preset compensation value and the preset imaging control parameter, determine a target imaging control parameter that satisfies the preset image formation condition, using the preset algorithm.

[50] The image formation control unit may, in particular, determine a first preset intermediate transformation parameter based on the first environment data and a stored corresponding relationship between the environment data and the intermediate transformation parameters.

[51] It can be seen that the corresponding relationship between the environment data and the intermediate conversion parameters can be preset and stored in the imaging device, and in particular stored in the memory unit of the imaging device, and can also be stored directly in the computer program included in the imaging control unit, without the limitation specified in this document.

[52] The corresponding relationship between the environment data and the intermediate conversion parameters may be pre-stored in the image forming device and may be consistent with the above-mentioned corresponding relationship between the environment data and the intermediate conversion parameters stored in the chip control unit.

[53] In particular, the above-mentioned first environmental data may include first temperature data and first humidity data; and when determining the first preset intermediate conversion parameter, the image forming control unit may first determine an intermediate temperature conversion parameter corresponding to the first temperature data, based on the first temperature data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters, and determine an intermediate humidity conversion parameter corresponding to the first humidity data, based on the first humidity data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters. The image forming control unit may perform conversion processing using a preset second conversion algorithm based on the intermediate temperature conversion parameter, the intermediate humidity conversion parameter and the first conversion parameter to obtain a preset compensation value.

[54] It is obvious that in the above-mentioned process, in order to prevent measurement errors between the first environmental data relating to the internal environment of the imaging device and the second environmental data relating to the environment in which the consumable chip is currently located from influencing the intermediate conversion parameter, when the imaging control unit determines the intermediate conversion parameter, the imaging control unit can adaptively determine the range of environmental data in which the first environmental data is located and attempt to determine the first preset intermediate conversion parameter according to each environmental data within the range of environmental data; thus, the influence caused by measurement errors can be avoided.

[55] In particular, the image formation control unit may determine a current encoding value of the environment data based on the first environment data and the stored corresponding relationship between the data and the intermediate transformation parameters; determine other encoding values of the environment data that are borderline with the aforementioned current encoding values of the environment data, thereby obtaining a plurality of encoding combinations including the current encoding value of the environment data and the other encoding values of the environment data;

[56] select any coding combination from the above-mentioned plurality of coding combinations as the above-mentioned first preset intermediate transformation parameter, perform transformation processing on the first transformation parameter using a preset second transformation algorithm based on the first preset intermediate transformation parameter, and determine whether a preset compensation value is obtained; if not, select the next coding combination in the plurality of coding combinations as the first preset intermediate transformation parameter, and perform transformation processing for the above-mentioned first transformation parameter using a preset second transformation algorithm until the above-mentioned preset compensation value is obtained or approx. completion of the transformation processing performed for the above-mentioned first transformation parameter using all of the above-mentioned plurality of coding combinations.

[57] The other environment data encoding values that are boundary values of the current environment data encoding value may be a set of environment data encoding values that are boundary values of the current environment data encoding value, that is, a set of environment data encoding values that are boundary values of the current environment data encoding value in accordance with a stored corresponding relationship between the environment data and the intermediate transformation parameters.

[58] In particular, when the first environmental data includes the first temperature data and the first humidity data, the image forming control unit may, based on the first environmental data and the stored corresponding relationship between the environmental data and the intermediate conversion parameters, respectively determine a current temperature encoding value matched with the first temperature data and a current humidity encoding value matched with the first humidity data. Then, the image forming control unit may determine other temperature encoding values that are borderline with the current temperature encoding value and determine other humidity encoding values that are borderline with the current humidity encoding value.

[59] According to the current temperature encoding value, other temperature encoding values, the current humidity encoding value and other humidity encoding values, a plurality of encoding combinations may be determined, including any of the temperature encoding values and any of the humidity encoding values; any encoding combination of the plurality of encoding combinations may be selected as a first preset intermediate transformation parameter to perform transformation processing on the first transformation parameter using a preset second transformation algorithm to determine whether a preset compensation value is obtained; if not, the next encoding combination in the plurality of encoding combinations may be selected as a first preset intermediate transformation parameter to perform transformation processing on the first transformation parameter using a preset second transformation algorithm until a preset compensation value is obtained or transformation processing on the first transformation parameter is completed using all encoding combinations in the plurality of encoding combinations.

[60] Furthermore, in one embodiment, the above-mentioned first preset intermediate transformation parameter may be a decryption key, and the second transformation algorithm may be a decryption algorithm. After receiving the first transformation parameter corresponding to the preset compensation value, that is, the preset compensation value after the encryption processing, the image forming control unit may perform decryption processing of the above-mentioned first transformation parameter based on the first preset intermediate transformation parameter, using the second transformation algorithm to obtain the preset compensation value. The above-mentioned preset image forming control parameter may be set according to the operating parameter of the image forming device and the operating parameter of the consumable element.

[61] In an image formation control method provided in one embodiment, a first detection unit may detect first environmental data on the printer side, and a second detection module may detect second environmental data on the chip side, so that according to a second preset intermediate transformation parameter corresponding to the second environmental data, the chip control unit may perform encryption processing on a preset compensation value of the image formation control parameter corresponding to the second environmental data using a first transformation algorithm to obtain a first transformation parameter corresponding to the preset compensation value, and the first transformation parameter may be sent to the image formation control unit; after receiving the first transformation parameter, the image formation control unit may, based on the first preset intermediate transformation parameter corresponding to the first environmental data, perform decryption processing for the above-mentioned first transformation parameter using a second transformation algorithm to obtain a preset compensation value; and the image formation control unit may determine a target image formation control parameter according to the preset compensation value and the preset image formation control parameter. The preset compensation value can be encrypted and decrypted based on the environment data to prevent interception and interference with the preset compensation value during transmission, making data transmission more secure, thereby ensuring the quality of printing and image formation.

[62] In this case, in order to ensure that the above-mentioned preset compensation value is obtained in time, it may optionally be determined whether the second detection unit is faulty based on the first environmental data and the second environmental data. Specifically, before step 203, the image formation control method may further include:

[63] sending, by the chip control unit, second medium data to the imaging device; and

[64] determining, by the imaging device, whether the second environment data satisfies the expectation, based on the second environment data and the first environment data related to the environment in which the imaging device is currently located.

[65] In one embodiment, after the imaging device receives the second environmental data from the chip side, the second environmental data may be compared with the first environmental data on the imaging device side. If the difference between the second environmental data and the first environmental data is within a certain predetermined range, that is, the absolute value of the above-mentioned difference is less than or equal to a predetermined threshold, the second environmental data can be used, that is, there is no malfunction in the second detection unit; so that the predetermined compensation value corresponding to the imaging control parameter can be obtained correctly, that is, it is determined that the imaging quality that meets the expectation can be obtained by using the imaging consumable. If it is determined that the absolute value of the above-mentioned difference is greater than the predetermined threshold, it is determined that the second environmental data is unusable, and the second detection unit deviates from the norm; so that the predetermined compensation value corresponding to the imaging control parameter cannot be obtained correctly; When using the image-forming consumable, the image-forming quality cannot meet expectations. Therefore, a prompt message may be displayed indicating that the second detection unit, which detects the environment in which the consumable chip is located, is faulty, and the image-forming quality when using the consumable may not meet expectations. The user may also be prompted to continue printing, and the decision on whether to use the image-forming consumable may be made in accordance with the user's choice.

[66] The image formation control method provided in one embodiment can determine whether the second detection unit is faulty in time, that is, whether the chip-side sensor is faulty in time, thereby avoiding the problem that the preset compensation value corresponding to the image formation control parameter is not reached in time, resulting in a failure or poor print quality. Furthermore, when the chip-side sensor is faulty, it cannot be determined in real time whether the printing material, such as toners stored in the consumable, is in the desired state. Therefore, even if the storage conditions of the printing material are poor, the consumable can still be used for printing, which can cause the problem of poor image formation quality.

[67] Furthermore, in a further embodiment, after the image forming device (also referred to as the printer side) receives the first conversion parameter corresponding to the preset compensation value of the image forming control parameter sent by the consumable chip, a situation may arise in which the preset compensation value cannot be obtained after decryption processing. In such a case, it may be considered that the detection unit for detecting the environment data of the image forming device or the consumable chip may be faulty, and a signal may be output notifying of the above-mentioned case.

[68] That is, if the conversion processing based on the first preset intermediate conversion parameter and the first conversion parameter using the preset second conversion algorithm does not obtain the preset compensation value, the method may also include issuing a message signaling that the consumable chip is faulty.

[69] In one embodiment, if the imaging control unit does not obtain the preset compensation value after the decryption process, the consumable chip may be faulty at that time, and the imaging control unit may generate a signal information instruction for controlling the signal device to issue a warning about the faulty consumable chip or display a prompt message on the display unit of the imaging device.

[70] Optionally, the above-mentioned signaling device may include a buzzer and a control indicator, without being particularly limited to the above. For example, when the imaging control unit fails to obtain the preset compensation value after the decryption process, it may generate a corresponding signaling information instruction to control the buzzer to emit a buzzing sound and control the control indicator to emit a red light.

[71] The imaging control method provided in one embodiment can promptly signal a malfunction of the consumable chip when the imaging control unit cannot obtain a preset compensation value after decryption processing, that is, when the consumable chip is malfunctioning, so that the user can detect the malfunction of the consumable chip in time, and then repair or replace the consumable chip in time.

[72] To further explain the image formation control method shown in Fig. 4, the method is described in detail below.

[73] Fig. 4 illustrates a signal exchange diagram provided by exemplary embodiments of the present invention. In one embodiment, a printer may be taken as an example of an image forming device for implementing information exchange between the image forming device and a consumable chip. In particular, information exchange between an image forming control unit on the printer side and a chip control unit on the chip side may be used for the description; and environmental data may include temperature and humidity data.

[74] As shown in Fig. 4, the method for controlling image formation may include the following steps.

[75] At step 301, after the printer is started, the printer and the consumable chip may undergo cross-authentication.

[76] In one embodiment, the above-mentioned cross-authentication may provide that the image formation control unit on the printer side and the chip control unit on the chip side may perform authentication including exchanging random numbers.

[77] In step 302, the image formation control unit may send a data preparation instruction to the chip control unit; after receiving the data preparation instruction, the chip control unit may perform data preparation on the chip side and send a data preparation status instruction to the image formation control unit; and after receiving the data preparation status instruction, the image formation control unit may perform data preparation on the printer side.

[78] In one embodiment, after receiving the data preparation instruction, the chip control unit may perform data preparation on the chip side. The second detection unit may detect second environmental data related to the environment in which the consumable chip is currently located, wherein the second environmental data may include second temperature data and second humidity data. Accordingly, the second detection unit may include a second temperature sensor and a second humidity sensor.

[79] Specifically, after the chip control unit receives the data preparation command, the second temperature sensor may detect second temperature data of the environment in which the consumable chip is currently located, and the second humidity sensor may detect second humidity data of the environment in which the consumable chip is currently located.

[80] After receiving the data preparation state instruction, the image forming control unit may perform data preparation on the printer side, and the first detection unit may detect first environment data related to the internal environment of the image forming device.

[81] In this case, after receiving the data preparation state instruction, the image formation control unit may send a request instruction to the chip control unit, and the above-mentioned request instruction may, in particular, be a request instruction for the data preparation state of the chip.

[82] In step 303, the chip control unit may determine a preset compensation value of the imaging control parameter based on the second environmental data and a stored corresponding relationship between the environmental data and the compensation values corresponding to the imaging control parameters.

[83] In one embodiment, the corresponding relationship between the second environment data and the stored corresponding relationship between the environment data and the compensation values corresponding to the image formation control parameters may be a two-dimensional array relationship, i.e., only one output Z can be obtained by inputting X and Y.

[84] In particular, the microcircuit control unit may determine a preset compensation value based on the second temperature data, the second humidity data and a stored corresponding relationship between the environmental data and the compensation values corresponding to the image formation control parameters, that is, the preset compensation value of the image formation control parameter may be determined according to the second temperature data and the second humidity data.

[85] At step 304, the chip control unit may determine a second preset intermediate conversion parameter based on the second environment data and the stored corresponding relationship between the environment data and the intermediate conversion parameters.

[86] In particular, the control unit of the microcircuit may determine an intermediate temperature conversion parameter, that is, a current second temperature encoding value that matches the second temperature data corresponding to the second temperature data based on the second temperature data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters; and determine an intermediate humidity conversion parameter, that is, a current second humidity encoding value that matches the second humidity data corresponding to the second humidity data based on the second humidity data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters.

[87] Furthermore, the coding combination may be formed according to the current second temperature coding value and the current second humidity coding value, thereby determining the second preset intermediate conversion parameter.

[88] The chip control unit may perform conversion processing according to the preset compensation value using the first conversion algorithm based on the second preset intermediate conversion parameter to obtain the first conversion parameter corresponding to the preset compensation value. After obtaining the first conversion parameter corresponding to the aforementioned preset compensation value, the chip control unit may control the data preparation state of the chip, which is to be displayed as the data ready state.

[89] In this case, after requesting that the data preparation state of the chip is displayed as the data ready state, the image formation control unit may send a data reading instruction to the chip control unit; and after receiving the data reading instruction, the chip control unit may send the first conversion parameter to the image formation control unit.

[90] At step 305, the image formation control unit may determine a first preset intermediate transformation parameter based on the first environment data and a stored corresponding relationship between the environment data and the intermediate transformation parameter.

[91] In one embodiment, the first environmental data may include first temperature data and first humidity data. Accordingly, the first detection unit may include a first temperature sensor and a first humidity sensor.

[92] In particular, the control unit of the microcircuit may determine an intermediate temperature conversion parameter, that is, a current second temperature encoding value that matches the second temperature data corresponding to the second temperature data based on the second temperature data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters; and determine an intermediate humidity conversion parameter, that is, a current second humidity encoding value that matches the second humidity data corresponding to the second humidity data based on the second humidity data and a stored corresponding relationship between the environmental data and the intermediate conversion parameters.

[93] In this case, the coding combination can be formed according to the current first coding value of the temperature and the current first coding value of the humidity, thereby determining the first preset intermediate conversion parameter.

[94] In step 306, the imaging control unit may perform conversion processing based on the first preset intermediate conversion parameter, for the first conversion parameter using a preset second conversion algorithm to obtain a preset compensation value; and, based on the preset compensation value and the preset imaging control parameter, may determine a target imaging control parameter satisfying the preset imaging condition using the preset algorithm.

[95] For example, Table 1 is a table of the temperature range of the corresponding relationship between the environmental data and the intermediate conversion parameters provided by the present invention; and Table 2 is a table of the humidity range of the corresponding relationship between the environmental data and the intermediate conversion parameters provided by the present invention.

Table 2 Humidity range table Range code number Humidity range 0xFF00 0%~10% 0xFE00 10%~20% 0xFD00 20%~30% 0xFC00 30%~40% 0xFB00 40%~50% 0xFA00 50%~60% 0xF900 60%~70% 0xF800 70%~80% 0xF700 80%~90% 0xF600 90%~100%

[96] On the consumable chip side, the second environment data related to the current environment of the consumable chip detected by the second detection unit may include the second temperature data of 30 degrees and the second humidity data of 25%, so that the current temperature encoding value 0x0019 can be determined according to Table 1 and the second environment data, and the current humidity encoding value 0xFD00 can be determined according to the second environment data and Table 2. In this way, the current humidity encoding value and the current temperature encoding value can be determined, thereby determining the second preset intermediate conversion parameter.

[97] The manner of determining the first preset intermediate conversion parameter on the printer side may be the same as determining the second preset intermediate conversion parameter on the chip side, and may not be described in detail here.

[98] Thus, the chip control unit may generate a first conversion parameter using a preset algorithm based on a determined second preset intermediate conversion parameter and a preset image formation control parameter compensation value, and send the first conversion parameter to the printer; and the printer may generate a preset compensation value using a preset algorithm based on the determined first preset intermediate conversion parameter and the first conversion parameter, thereby determining a target image formation control parameter.

[99] In the above-mentioned manner of determining the target image formation control parameter, the second preset intermediate conversion parameter corresponding to the consumable chip side and the first preset intermediate conversion parameter corresponding to the printer side may correspond to each other. In order to prevent measurement errors between the first environment data related to the internal environment of the image forming device and the second environment data related to the environment in which the consumable chip is currently located from influencing the intermediate conversion parameter, when the image formation control unit determines the intermediate conversion parameter, the image formation control unit may adaptively determine the range of the environment data in which the first environment data is located and attempt to determine the first preset intermediate conversion parameter according to each environment data within the range of the environment data; thus, the influence caused by measurement errors can be avoided.

[100] For example, according to the current temperature encoding value, a previous temperature encoding value and a next temperature encoding value that is a boundary of the current temperature encoding value can be determined; and according to the current humidity encoding value, a previous humidity encoding value and a next humidity encoding value that is a boundary of the current humidity encoding value can be determined. According to the current temperature encoding value, the previous temperature encoding value and the next temperature encoding value, and also according to the current humidity encoding value, the previous humidity encoding value and the next humidity encoding value, a plurality of encoding combinations can be determined, including any temperature encoding value and any humidity encoding value.

[101] For example, according to Table 1 and Table 2, the current temperature encoding value, the previous temperature encoding value, and the next temperature encoding value are 0x0011, 0x0010, and 0x0012, respectively; and the current humidity encoding value, the previous humidity encoding value, and the next humidity encoding value are 0xFB00, 0xFA00, 0xFC00, respectively. Thus, the obtained set of encoding combinations may include 0x00100xFA00, 0x00100xFB00, 0x00100xFC00, 0x00110xFA00, 0x00110xFB00, 0x00110xFC00, 0x00120xFA00, 0x00120xFB00 and 0x00120xFC00.

[102] Any coding combination from the above-mentioned plurality of coding combinations may be selected as a first preset intermediate transformation parameter for performing transformation processing on the first transformation parameter using a preset second transformation algorithm and determining whether a preset compensation value is obtained. If not, the next coding combination in the plurality of coding combinations may be selected as the first preset intermediate transformation parameter, and transformation processing may be performed for the first transformation parameter using a preset second transformation algorithm until a preset compensation value is obtained or transformation processing performed for the first transformation parameter using all coding combinations is completed.

[103] That is, ultimately, based on the first preset intermediate transformation parameter, transformation processing can be performed for the first transformation parameter using a preset second transformation algorithm to obtain a preset compensation value; and based on the preset compensation value and the preset image formation control parameter, a target image formation control parameter satisfying the preset image formation condition can be determined using the preset algorithm.

[104] Or, if the printer completes processing the first conversion parameter with the second conversion algorithm using all encoding combinations, the preset compensation value is not obtained. Therefore, the first detection unit and/or the second detection unit may be faulty, that is, the printer-side sensor and/or the chip-side sensor may be faulty. At this point, a signal may be generated to remind the user to check and replace the aforementioned sensors in a timely manner.

[105] By this point, the printer and the consumable chip may have completed the exchange.

[106] For the image formation control method provided by the embodiments of the present invention, encryption and decryption processing and transmission can be performed based on a preset compensation value of an image formation control parameter based on environmental data using environmental data detected by the consumable chip and the image formation device. Interception and manipulation of the preset compensation value during transmission can be prevented, which makes it possible to make data transmission more secure, thereby ensuring the quality of printing and image formation.

[117] Option three

[118] Generally, after completing an image forming operation, the image forming device may also need to write data such as the page number of the printed paper, the toner consumption, etc., to the consumable chip. However, in the existing technology, the image forming device and the consumable chip can usually communicate by exchanging encryption codes, which can be easily intercepted for analysis and manipulation. As a result, the consumable chip may incorrectly record the service life information of the consumable item, which may lead to an incorrect determination of the service life of the consumable item; the user may not be correctly prompted to replace the consumable item, which causes inconvenience to the user; and this may cause problems in that a consumable item whose service life has not expired is mistakenly considered to be expired, and the user is prompted to replace the consumable item, and/or a consumable item whose service life is approaching is mistakenly considered to be fit for continued use, and the user is not prompted to replace the consumable item in time.

[119] In order to solve the above-mentioned technical problem, as shown in Fig. 7, embodiments of the present invention provide a method for controlling image formation, including the following steps.

[120] In step 701, the image forming control unit may obtain data to be recorded that is to be recorded in the consumable chip and verification data configured to determine the correctness of the data to be recorded; and generate a second conversion parameter based on the above-mentioned data to be recorded, the above-mentioned verification data and a third preset intermediate conversion parameter, and send the above-mentioned second conversion parameter to the consumable chip.

[121] After the image forming device completes the image forming operation, the image forming control unit may obtain the above-mentioned recordable data and verification data configured to determine the correctness of the recordable data; wherein the above-mentioned recordable data may include, but are not limited to, the number of printed pages, print size, toner consumption, average coverage, and the like, which may not be limited in this document.

[122] The disclosed embodiments of the invention may not limit the methods of using verification data for verifying the correctness of data to be recorded; and the above-mentioned verification data may be equality check data, CRC check data, and the like.

[123] The above-mentioned second preset intermediate transformation parameter can be obtained, in particular, by performing the following steps:

[124] getting a pre-installed code book;

[125] obtaining the first preset key index value; and

[126] generating a third preset intermediate parameter based on the preset codebook and the first preset key index value.

[127] In particular, embodiments of the present invention may not limit the method of obtaining a preset codebook by the imaging device. The preset codebook may be directly generated by the imaging device in accordance with a preset rule as required, for example, by using a random number generator to generate the preset codebook, or may be obtained by the imaging control unit through communication with a consumable chip or other computer equipment connected to the imaging device.

[128] The above-mentioned preset codebook may have a one-dimensional form, in particular, it may be data with a fixed byte length. For example, the preset codebook may be data consisting of 0s and 1s, with a length of 255 bytes.

[129] The above-mentioned preset codebook can also be set in two-dimensional and three-dimensional forms, if required. For example, when the preset codebook has a two-dimensional form, a certain data length can be set in the horizontal direction, and a certain data length can be set in the vertical direction of the preset codebook.

[130] In one embodiment of the present invention, determining the first preset key index value may be associated with data of the internal environment of the imaging device.

[131] In particular, the corresponding encoding value of the environment data may be determined based on the internal environment data corresponding to the imaging device and a previously stored corresponding relationship between the environment data and the preset intermediate parameters; wherein the first preset key index value may be determined based on the encoding value of the environment data.

[132] Furthermore, the determination of the first preset key index value may also be associated with the above-mentioned medium data encoding value and preset counting information corresponding to the data recording instruction sent by the imaging device to the consumable chip. The preset counting information may, in particular, be a data recording sequence number corresponding to the current data recording instruction, which may be referred to as a data recording sequence number hereinafter for brevity. That is, the first preset key index value may be generated according to a preset algorithm based on the above-mentioned medium data encoding value and the data recording sequence number.

[133] In addition, when the preset codebook has a one-dimensional form, in the embodiments of the present invention, the above-mentioned key index value may also be determined based on the above-mentioned medium data encoding value, the data record sequence number, the byte length of the preset codebook and the sequence number of the consumable chip, thereby determining the above-mentioned third preset intermediate conversion parameter.

[134] As a result, the imaging device can send each data writing instruction to the consumable chip. Each data writing instruction corresponds to a different data writing sequence number, so that even if the medium data detected by the imaging device is the same for different data writing instructions, the first preset key index values corresponding to the aforementioned data writing instructions may also be different. Therefore, the third preset intermediate parameters corresponding to the aforementioned data writing instructions may also be different. The aforementioned preset counting information can also be replaced with other data, for example, dynamic parameters that change along with the timing information of the data writing instructions sent by the imaging device to the consumable chip, etc., provided that the first preset key index values generated in accordance with different data writing instructions are different.

[135] For example, it is assumed that the preset codebook is one-dimensional data, the byte length is L, the data record sequence number is N, the serial number of the consumable chip is SN, the third medium data detected by the imaging device is T1, and the fourth medium data detected by the consumable chip is T2. The third medium data T1 and the fourth medium data T2 may be data at the same time, or a small time interval may exist between the times corresponding to the third medium data T1 and the fourth medium data T2. Such time may be a time corresponding to a certain time interval delayed after the imaging control unit sends a preset instruction to the consumable chip. The time interval can be set as necessary and in accordance with the communication speed between the imaging device and the consumable chip, as well as the response speed of the consumable chip. The preset instruction may be an instruction for notifying the consumable chip of the preparation of environment data, etc., which cannot be limited in this document. It should be understood that the timing of the aforementioned third environment data T1 and fourth environment data T2 may differ from the aforementioned detected timing of the first environment data and second environment data.

[136] In one embodiment of the present disclosure, it should be understood that the third predetermined intermediate transformation parameter may be, in particular, an encryption key.

[137] The image forming control unit may first determine an encoding value K1 corresponding to the third media data T1 based on the third media data T1 and a previously stored corresponding relationship between the media data and the preset intermediate parameters; then, a key index value may be generated based on the encoding value K1, the serial number SN of the consumable chip, the serial number of the data record N, and the byte length L of the preset codebook; and the corresponding key, that is, the third preset intermediate conversion parameter, may be determined based on the key index value and the preset codebook.

[138] For example, the ciphertext data record number N is 0x01, the serial number SN of the consumable chip is AA2A000000000000000000000000000000, the encoding value K1 is 0x3F; and the above-mentioned preset key index value can be determined by performing the following steps.

[139] In step 1, an XOR operation may be performed on the ciphertext data record number N and the serial number SN to obtain (AB2B0101010101010101010101010101);

[140] in step 2, an XOR operation may be performed on the data obtained in step 1 and the encoding value 0x3F to obtain (94143E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E3E); and

[141] in step 3, the obtained value can be used as a key index, that is, INDEX = (0x94,0x14,0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E, 0x3E). After completing the determination of the first preset key index value, the byte data of the INDEX[n]%L bit can be taken from the codebook with the byte length L as the n-th byte of the third preset intermediate parameter P.

[142] It should be noted that the process of determining the encoding value of the environment data by the image forming control unit based on the environment data, the stored corresponding relationship between the environment data and the preset intermediate parameters may refer to the description of the above-mentioned embodiments, without being particularly limited to the above.

[143] After completing the determination of the third preset intermediate conversion parameter, the image forming control unit may generate a second conversion parameter based on the above-mentioned data to be recorded, the above-mentioned verification data and the above-mentioned preset intermediate conversion parameter; and send the second conversion parameter to the consumable chip.

[144] It should be understood that the above-mentioned data to be recorded and the verification data corresponding to the above-mentioned data to be recorded may form complete data in accordance with a predetermined rule, where the previous plurality of consecutive bytes corresponding to the complete data may be the above-mentioned data to be recorded, and the subsequent plurality of consecutive bytes corresponding to the complete data may be the verification data corresponding to the above-mentioned data to be recorded.

[145] In step 702, the consumable chip may send predetermined response information to the image formation control unit based on the second conversion parameter. The predetermined response information may be configured to determine whether the data to be recorded has been successfully recorded in the consumable chip.

[146] After receiving the second conversion parameter sent by the imaging control unit, the consumable chip may send predetermined response information to the imaging control unit; and after receiving the predetermined response information, the imaging control unit may use the third intermediate conversion parameter to perform conversion processing with respect to the predetermined response information and may determine whether the data to be recorded has been successfully recorded in the consumable chip according to the result of the conversion processing.

[147] As shown in Fig. 8, step 702 may, in particular, include the following steps.

[148] In step 7020, the consumable chip may receive the second conversion parameter and perform conversion processing based on the second conversion parameter and the fourth preset intermediate parameter.

[149] At step 7030, it may be determined whether the conversion processing was successful.

[150] If yes, step 7040 is performed; and if no, step 7050 is performed.

[151] In step 7040, a third conversion parameter may be generated based on the fourth preset intermediate parameter and the recorded data that has been recorded in the consumable chip, and the third conversion parameter may be sent to the image formation control unit.

[152] In step 7050, based on the fourth preset intermediate parameter, a hint message indicating that the conversion processing has failed may be sent to the image formation control unit.

[153] At step 7020, determining the fourth preset intermediate parameter may also be associated with fourth environmental data corresponding to the consumable chip and the preset codebook received from the imaging device.

[154] The above-mentioned fourth preset intermediate parameter can be determined by performing the following steps:

[155] receiving a preset code book sent by an imaging device;

[156] obtaining a second preset key index value; and

[157] generating a fourth preset intermediate parameter based on the preset codebook and the first preset key index value.

[158] The determination of the second preset key index value may be associated with the fourth environment data corresponding to the consumable chip.

[159] The manner of generating the second preset key index value may be similar to the manner of creating the aforementioned first preset key index, with a difference based on various environmental data that may not be described in detail here.

[160] In one embodiment of the present invention, it is implied that the aforementioned fourth predetermined intermediate transformation parameter may, in particular, be a decryption key.

[161] The generation of the fourth preset transformation parameter may be based on the above-mentioned current data encoding value. In this case, other environment data encoding values, bordering on the current environment data encoding value, may be determined based on the current environment data encoding value, so that a plurality of encoding combinations may be obtained, including the current environment data encoding value and other environment data encoding values; and one encoding combination may be selected from the plurality of encoding combinations to generate the fourth preset intermediate parameter in accordance with the above, so that a fourth preset intermediate parameter corresponding to the above-mentioned plurality of encoding combinations may be obtained.

[162] It should be understood that the process of determining the current encoding value of the environment data and/or other encoding values of the environment data according to the environment data may be similar to the process of determining the current encoding value of the environment data and/or other encoding values of the environment data by the imaging device according to the environment data in the above-mentioned embodiments, which may not be described in detail here.

[163] In step 7020, when a fourth preset intermediate parameter is generated based only on the above-mentioned current environment encoding value, the consumable chip may use the fourth preset intermediate transformation parameter to perform transformation processing on the second transformation parameter to obtain transformed result data; the recordable data and the verification data in the result data may be identified according to the composition form of the above-mentioned recordable data and the verification data corresponding to the recordable data, and the verification data may be configured to verify the recordable data; if the verification is successful, it may be determined that the transformation process of the second transformation parameter is successful; and if the verification fails, it may be determined that the transformation processing of the second transformation parameter has failed.

[164] In embodiments of the present invention, an encoding combination may also be selected from the above-mentioned plurality of encoding combinations, and a fourth preset intermediate parameter corresponding to the encoding combination may be obtained; the fourth preset intermediate parameter may be configured to perform transformation processing on a second transformation parameter, and it may be determined whether the current transformation processing is successful; if not, the next encoding combination of the plurality of encoding combinations may be configured to generate a corresponding fourth preset intermediate parameter, after which the fourth preset intermediate parameter may be configured to perform transformation processing on the second transformation parameter, until it is determined that the transformation processing is successful or the transformation processing performed for the second transformation parameter using the fourth preset intermediate parameters corresponding to all encoding combinations is completed.

[165] If the transformation processing performed for the second transformation parameter by the fourth preset intermediate parameter corresponding to one encoding combination in the above-mentioned plurality of encoding combinations is successful, it may be determined that the transformation processing according to the second transformation parameter is successful; and if the result of the transformation processing performed for the second transformation parameter by the fourth preset intermediate parameters corresponding to all encoding combinations in the above-mentioned plurality of encoding combinations is unsuccessful, it may be determined that the transformation processing according to the second transformation parameter has failed.

[166] It should be understood that in one embodiment of the present invention, the transformation processing may, in particular, be a decryption processing.

[167] If it is determined that the processing of the transformation of the second transformation parameter is unsuccessful, it may be determined that the preset response information is a hint message indicating that the processing of the transformation has failed, wherein the preset response information may be plain text data.

[168] If it determines that the conversion processing of the second conversion parameter has been successful, it may determine that the preset response information may be a third conversion parameter generated by encrypting the recorded data that has been written to the consumable chip using a fourth preset intermediate parameter; after receiving the third conversion parameter, the image forming device may use the third intermediate conversion parameter to perform conversion processing for the third conversion parameter and compare the converted data with the aforementioned data to be written to determine whether the data-be-writing should be correctly written to the consumable chip; and if so, this data writing operation may be terminated.

[169] In one embodiment of the present invention, when writing data to a consumable chip, the data to be written can be encrypted, decrypted, and transmitted using the medium data detected by the consumable chip and the imaging device, respectively. In this way, it is possible to avoid the problem that, during the process of transmitting and writing the data to be written to the consumable chip by the imaging device, the service life of the consumable may be incorrectly determined due to malicious interference with the data to be written, which may easily cause problems in that a consumable whose service life has not expired is mistakenly considered to be expired, and the user is prompted to replace the consumable, and/or a consumable whose service life is approaching is mistakenly considered fit for continued use, and the user is not prompted to replace the consumable in time.
