  The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus that predicts a job end time.

  Japanese Patent Application Laid-Open No. 2004-228561 discloses an image forming apparatus having a function of predicting and displaying a job end time. One purpose of predicting and displaying the job end time is to allow the user to effectively use the time during which the image forming apparatus is executing the job.

JP 2009-90592 A

  However, an error may occur between the predicted end time of the job and the actual end time of the job. One cause of the error is execution of adjustment control by the image forming apparatus. For example, when a predetermined condition is satisfied during execution of the job, the image forming apparatus interrupts the job, executes predetermined adjustment control, and then restarts the job. As a result, the actual job end time becomes later than the predicted end time. In this case, even if the printed matter is picked up at the end time of the job input by the user, the job is not ended, and the user must wait at the image forming apparatus until the end of the job. Also, when the user submits the next job after the end of a certain job that has been submitted, if the actual end time is earlier than the predicted end time of the job, it will be downgraded to the image forming apparatus until the next job is submitted. Time is generated.

  The present invention provides an image forming apparatus capable of appropriately presenting a job end time to a user.

  According to an aspect of the invention, the image forming apparatus includes: a receiving unit that receives a job; a printing unit that performs a process of printing an image on one or more sheets based on the job received by the receiving unit; As the processing time from the start to the completion of the received job, a prediction unit capable of predicting a first processing time and a second processing time longer than the first processing time, and the receiving unit based on the processing time predicted by the prediction unit Control means for performing control to display the end time of the job accepted by the user, and selection means for allowing the user to select a display mode, wherein the control mode has the first mode selected as the display mode. The first end time based on the first processing time is displayed as the end time of the job received by the receiving means, and the second mode is selected as the display mode. When is, as the end time of the job that the reception unit receives, and performs control to display a second end time based on the second processing time.

  According to the present invention, the job end time can be appropriately presented to the user.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. In addition, the following embodiment is an illustration and does not limit this invention to the content of embodiment. In the following drawings, components that are not necessary for the description of the embodiments are omitted from the drawings.

  FIG. 1 is a configuration diagram of an image forming apparatus 10 according to the present embodiment. The image forming apparatus 10 includes a reading unit 200 that reads an image from a document, and a printer unit 350 that prints an image read by the reading unit 200 on a sheet. The document feeder 100 feeds documents set upward on the document tray 101 one by one from the first page to the conveyance path one by one. The document fed to the transport path is transported on the platen glass 102 from the left to the right in the drawing, and is discharged to the paper discharge tray 112. The lamp 103 of the scanner unit 104 irradiates light toward the original conveyed on the platen glass 102. Reflected light from the original of the light irradiated by the lamp 103 is guided to the lens 108 via the mirrors 105, 106, and 107. The light that has passed through the lens 108 forms an image on the imaging surface of the image sensor 109, whereby the image sensor 109 outputs image data. This image data is input as a video signal to the exposure unit 110 of the printer unit 350.

  Note that, as described above, a method in which the scanner unit 104 is fixed at a certain position and an image of a conveyed document is read is called “flow-reading”. On the other hand, the image forming apparatus 10 can also read an image of a document placed on the platen glass 102 by causing the scanner unit 104 to scan from left to right. This reading method is called original fixed reading. In the fixed document reading, the document is conveyed onto the platen glass 102 by the document feeder 100. Alternatively, in the fixed document reading, the user lifts the document feeder 100 and places the document on the platen glass 102.

  Next, printing on a sheet by the printer unit 350 will be described. The charger 135 charges the surface of the photoreceptor 111 to a uniform predetermined potential. The exposure unit 110 outputs light for exposing the photosensitive member 111 based on the video signal input from the reading unit 200. The light output from the exposure unit 110 is deflected by the polygon mirror 119 to scan and expose the photoconductor 111. As a result, an electrostatic latent image corresponding to the image indicated by the video signal is formed on the photoreceptor 111. The developing device 113 develops the electrostatic latent image on the photoconductor 111 with a developer, and forms a developer image on the photoconductor 111.

  On the other hand, sheets fed from the upper cassette 114 or the lower cassette 115 of the printer unit 350 by the pickup rollers 127 and 128 are conveyed toward the position of the registration roller 126 by the rollers 129, 130, and 136. When the sensor 132 detects the leading edge of the sheet, the conveyance of the sheet is temporarily stopped at the position of the registration roller 126. Similarly, when the sheet is fed from the manual feed tray 125 by the pickup roller 137, the sheet is similarly conveyed to the registration roller 126. The manual feed tray 125 has a detection sensor 133 that detects the presence or absence of a sheet on the manual feed tray, a detection sensor 134 that detects the size of the sheet in the conveyance direction, and a size in the width direction orthogonal to the conveyance direction of the sheet. And a detection sensor (not shown). The registration roller 126 conveys the sheet between the photoconductor 111 and the transfer unit 116 at a predetermined timing. The transfer unit 116 transfers the developer image formed on the photoconductor 111 to a sheet. The sheet on which the developer image is transferred is conveyed to the fixing unit 117. The fixing unit 117 fixes the developer image on the sheet by heating and pressing the sheet. The sheet that has passed through the fixing unit 117 is discharged to the outside of the image forming apparatus through the flapper 121 and the discharge roller 118.

  When the sheet is discharged with its image forming surface facing down (face-down), the sheet that has passed through the fixing unit 117 is once guided to the reverse path 122 by the switching operation of the flapper 121. Then, after the trailing edge of the sheet passes through the flapper 121, the sheet is switched back and discharged to the outside by the discharge roller 118. Further, when forming images on both sides of the sheet, the sheet is conveyed to the duplex conveyance path 124 after the sheet is guided to the reverse path 122 by the switching operation of the flapper 121. Thereafter, the sheet is conveyed again between the photoreceptor 111 and the transfer unit 116, and image formation is performed on the other surface of the sheet. The density detection sensor 138 is provided to detect the density of the developer image formed on the photoconductor 111. In addition, the image forming apparatus 10 includes an operation display device 600 that displays the state of the image forming apparatus 10 to the user and allows the user to make various inputs to the image forming apparatus 10.

  FIG. 2 shows the appearance of the operation display device 600. A start key 602 is a button for a user to perform a job input operation, that is, a button for starting an image forming operation. For example, when the user sets one or more documents on the document tray 101 and presses the start key 602, the image of each document on the document tray 101 is read by the reading unit 200, and an image corresponding to the image of each document. Data is output to the printer unit 350 as one job. A stop key 603 is a button for interrupting the image forming operation. Ten keys 604 to 613 are buttons for inputting numbers. In addition, the operation display device 600 includes a display unit 620. The display unit 620 is a touch panel, and the user can make various inputs to the image forming apparatus 10 by touching the display unit 620, and can check the state of the image forming apparatus 10 based on the display content of the display unit 620. it can. In the present embodiment, when the status confirmation key 617 is pressed, a job end time, which will be described later, is displayed on the display unit 620.

  FIG. 3 shows a control configuration of the image forming apparatus 10. The CPU circuit unit 900 includes a CPU 901, a ROM 902, and a RAM 903. The CPU 901 controls the entire image forming apparatus 10. The ROM 902 stores a control program executed by the CPU 901 and the like. The RAM 903 is used for temporarily storing data and the like used by the CPU 901 in the processing. The CPU 901, the ROM 902, and the RAM 903 are mutually connected by an address bus and a data bus.

  The document feeder control unit 911 controls driving of the document feeder 100 based on an instruction from the CPU circuit unit 900. The reading control unit 921 controls driving of the scanner unit 104, the image sensor 109, and the like, and transfers image data output from the image sensor 109 to the image signal control unit 922. The image signal control unit 922 performs each process on the image data from the image sensor 109 and outputs it to the printer control unit 931 as a video signal. The printer control unit 931 controls the printer unit 350 based on the input video signal, and performs printing processing on a sheet such as formation of a developer image on the photoreceptor 111 and sheet conveyance. The operation display device control unit 941 controls the operation display device 600 based on an instruction from the CPU circuit unit 900 to display a setting screen for image formation and a screen for paper jam processing.

  The CPU circuit unit 900 functions as a reception unit that receives jobs from the external computer 905 as well as jobs input by the user operating the operation display device 600. When a job from an external computer 905 is received, the image signal control unit 922 receives image data corresponding to an image formed by the job from the external computer 905 via the external I / F 904. The image signal control unit 922 performs various processes on the image data, and then outputs the image data to the printer control unit 931 as a video signal.

  FIG. 4 is a configuration diagram of the printer control unit 931. The image formation control unit 323 transfers the developer image onto the sheet by controlling the photoconductor 111, the developing unit 113, the transfer unit 116, the exposure unit 110, and the like. The fixing control unit 322 controls the fixing unit 117 to fix the developer on the sheet. The conveyance control unit 325 controls each roller and flapper for feeding and conveying a sheet.

  The image forming apparatus 10 performs adjustment control of the printer unit 350 for image formation. In the present embodiment, this adjustment control is wire cleaning control and density adjustment control. However, in the present invention, the adjustment control performed by the image forming apparatus 10 is not limited to wire cleaning control or density adjustment control.

  First, wire cleaning control will be described. FIG. 5 is a configuration diagram of the charger 135. The charger 135 includes a charging wire 150, a cleaning member 151, and a cleaning motor 152 for moving the cleaning member 151. The charger 135 is a so-called corona charger, and charges the photosensitive member 111 by corona discharge of the charging wire 150. In the process of increasing the number of times of charging, dirt adheres to the charging wire 150. Therefore, periodic cleaning of the charging wire 150 is necessary. For this reason, the cleaning member 151 is moved along the charging wire 150 by rotating the cleaning motor 152. The cleaning member 151 cleans the charging wire 150 in the process of moving along the charging wire 150.

  Next, density adjustment control will be described. The density adjustment control is periodically performed to suppress density deviation due to environmental changes, aging degradation, and the like. Specifically, a test pattern including developer images having a plurality of densities is formed on the photoreceptor 111. The density detection sensor 138 reads the test pattern of the photoconductor 111 and outputs a detection signal corresponding to the density of the read test pattern to the CPU 901. Based on the detection signal, the CPU 901 sets image forming conditions related to density such as a charging voltage by the charger 135 and the intensity of light emitted from the exposure unit 110.

  Next, prediction of job processing time will be described. The job processing time is the time required from the start to the completion of the job. In the present embodiment, the CPU 901 is configured so that the job processing time can be predicted as the longest time and the shortest time. Here, the longest time is the longest value among the predicted values of the time required from the start to the end of the job. On the other hand, the shortest time is the shortest value among the predicted values of the time required from the start to the end of the job. In this embodiment, the longest time is obtained by the sum of the predicted image formation time and the longest adjustment time. On the other hand, the shortest time is obtained by the sum of the predicted image formation time and the shortest adjustment time. The longest adjustment time is the longest predicted value of execution time of adjustment control performed during job execution, and the shortest adjustment time is the shortest predicted value of execution time of adjustment control performed during job execution.

  FIG. 6 is a flowchart of processing for calculating the longest time and the shortest time by the CPU 901. In step S10, the CPU 901 obtains a predicted image formation time. Here, the CPU 901 predicts the image forming time based on the number of prints designated by the job and the productivity (ppm) of the image forming apparatus 10. As shown in FIG. 7A, if the productivity of the image forming apparatus 10 for A4 sheets is 100 ppm, that is, 100 sheets per minute, the image forming time per A4 sheet is 60/100 = 0. .6 seconds. For example, in the case of a job that prints on 500 A4 sheets, 0.6 seconds × 500 sheets = 300 seconds is predicted as the image formation time. Returning to FIG. 6, the CPU 901 predicts the longest adjustment time in S11, and predicts the shortest adjustment time in S12. A method for predicting the longest adjustment time and the shortest adjustment time will be described later. In S13, the CPU 901 calculates the longest time by adding the predicted image formation time and the longest adjustment time, and in S14, calculates the shortest time by adding the predicted image formation time and the shortest adjustment time.

  Next, the longest adjustment time and the prediction of the shortest adjustment time will be described. As described above, in the present embodiment, the wire cleaning control and the density adjustment control will be described as examples. The longest adjustment time and the shortest adjustment time are predicted based on the execution condition and execution time of the adjustment control. FIG. 7B shows execution conditions and execution times of the wire cleaning control and the density adjustment control. As shown in FIG. 7B, the wire cleaning control is executed every time the number of printed sheets from the previous wire cleaning control reaches 2000 sheets. The time (execution time) required for one wire cleaning control is 30 seconds. The density adjustment control is executed when printing is performed on 100 sheets or more from the previous density adjustment control and there is a temperature change of 3 degrees or more from the temperature at the previous density adjustment control. The time required for one density adjustment control is 10 seconds. Note that each time wire cleaning control or density adjustment control is executed, the data of the cumulative number of formed images at the time of executing the adjustment control is stored in, for example, a backup area of the RAM 903 and held until the next adjustment control is performed. Is done.

  For example, consider a job that prints on 500 A4 sheets. In this case, the image formation time is predicted to be 0.6 × 500 = 300 seconds from FIG. Of the adjustment control, the wire cleaning control is performed once at the maximum, and the density adjustment control is performed five times at the maximum. Therefore, the longest adjustment time is predicted to be 30 × 1 + 10 × 5 = 80 seconds. Therefore, the longest time is predicted to be 300 + 80 = 380 seconds. On the other hand, if 500 sheets are printed and the number of printed sheets from the previous wire cleaning control does not reach 2000, the wire cleaning control is not executed during the job. In addition, the density adjustment control has a condition related to a temperature change. If this condition is not satisfied, the density adjustment control may not be performed even once during the job. Therefore, in this case, the shortest adjustment time is 0 seconds, and the shortest time is predicted to be 300 + 0 = 300 seconds.

  For example, consider a job for printing on 3000 A4 sheets. In this case, the image forming time is predicted to be 0.6 × 3000 = 1800 seconds from FIG. Of the adjustment control, the wire cleaning control is performed twice at the maximum, and the density adjustment control is performed 30 times at the maximum. Therefore, the longest adjustment time is predicted to be 30 × 2 + 10 × 30 = 360 seconds, and the longest time is predicted to be 1800 + 360 = 2160 seconds. On the other hand, in the adjustment control, the wire cleaning control may be performed only once, and the density adjustment control may not be performed once depending on the temperature condition. Therefore, the shortest adjustment time is predicted to be 30 × 1 + 10 × 0 = 30 seconds, and the shortest time is predicted to be 1800 + 30 = 1830 seconds.

  Thus, in this embodiment, the shortest adjustment time is obtained as the product of the minimum value (minimum number) of the number of times that the adjustment control execution condition is satisfied during the execution of the job and the time required for one adjustment control. Further, the longest adjustment time is obtained as a product of the maximum value (maximum number) of times that the adjustment control execution condition is satisfied during execution of the job and the time required for one adjustment control.

  The image forming apparatus 10 according to the present exemplary embodiment displays the end time of each job on the operation display device 600. Here, the image forming apparatus 10 displays the first mode displaying only the end time based on the shortest time, the second mode displaying only the end time based on the longest time, and the end time based on both the shortest time and the longest time. There are a total of three display modes including the third mode. The selection of the display mode is set in the image forming apparatus 10 by the user via the operation display device 600.

  FIG. 8 is a flowchart of processing for displaying the end time of a job. Note that the CPU 901 executes the processing of FIG. 8 in response to a display instruction input by the user. In the present embodiment, pressing the status confirmation key 617 shown in FIG. 4 corresponds to an input of a display instruction. In S <b> 20 and S <b> 21, the CPU 901 predicts the longest time and the shortest time for each incomplete job among the jobs that have already been submitted. Thereafter, in S22, the CPU 901 performs control to display the end time of each job on the operation display device 600 according to the display mode selected by the user.

  For example, FIG. 9 shows the contents displayed on the operation display device 600 when the status confirmation key 617 is pressed when there are three incomplete jobs shown in FIG. FIG. 10 also shows the longest time and the shortest time for each job. Note that each job is executed in order from top to bottom in the table of FIG. FIG. 9A shows the display content on the operation display device 600 when the first mode is selected as the display mode. As the end time of AAA.doc of the job to be executed first, 2 minutes 30 seconds which is the shortest time in FIG. 10 is displayed. The second BBB. For the end time of xls, AAA.doc and BBB. 3 minutes and 40 seconds are added to the shortest time of xls. Further, the third CCC. For the end time of ppt, AAA.doc and BBB. xls and CCC. 8 minutes and 40 seconds including the shortest time of ppt is displayed. In other words, when there are a plurality of jobs, the operation display device 600, for the second and subsequent jobs in the execution order, the processing time of the job and the processing times of all jobs executed before the job. Is displayed as the end time.

  FIG. 9B shows the display contents on the operation display device 600 when the second mode is selected as the display mode. As the job end time, the total value of the longest time of the job and the job executed before the job is displayed. FIG. 9C shows the display content on the operation display device 600 when the third mode is selected as the display mode. For each job, the end time is shown as a time range based on the shortest time and a time range based on the longest time.

  For example, when the user submits a job and picks up a printed material after the end time has elapsed, the user selects the second mode. As a result, when the user comes to pick up the printed matter, the job is finished, so that the user does not have to wait until the job is finished. Further, for example, when the next job is submitted when the end time of the submitted job has elapsed, the user selects the first mode. When the end time has elapsed, the job has not ended or has just ended, so the user can submit the next job without causing the image forming apparatus 10 to experience downtime. Furthermore, by selecting the third mode, the user can determine the time to go to the image forming apparatus 10 to pick up the printed material according to the usage. As a result, it is possible to suppress the occurrence of downtime in the image forming apparatus 10 and the necessity for the user to wait for the end of the job at the installation location of the image forming apparatus 10.

  For example, when the user presses the status confirmation key 617, if the first job, for example, a job related to AAA.doc in FIG. 10 is already being executed, the elapsed time from the start of the job is displayed. It can also be set as the structure which reduces and displays. For example, assume that when the user presses the status confirmation key 617, the elapsed time from the start of the job relating to AAA.doc in FIG. 10 is 30 seconds. In this case, the CPU 901 displays the end time of the job relating to AAA.doc as 2 minutes when the first mode is selected, and as 2 minutes and 20 seconds when the second mode is selected. However, when the third mode is selected, 2 minutes to 2 minutes and 20 seconds are displayed. Similarly, the end times of the second and third jobs are also displayed by being reduced by 30 seconds, which is the elapsed time of the first job when the user presses the status confirmation key 617, respectively. Further, the CPU 901 can display the end time of each job by the user pressing the status confirmation key 617, and then repeatedly reduce the end time of each job as the time elapses.

  Note that the wire cleaning control is executed in the middle of each job based on the number of printed sheets since the previous wire cleaning control was executed at the time of starting each uncompleted job and the number of printed sheets executed in each job. It can be determined whether or not. Regarding the density adjustment control, it is possible to determine whether or not “print on 100 sheets or more since the previous density adjustment control”, which is one of the execution conditions, is satisfied in the job. Therefore, the longest time and the shortest time may be determined based on this determination.

  It may be predicted that adjustment control is executed between an uncompleted job and the next uncompleted job. In such a case, the processing time of an incomplete job to be executed after execution of adjustment control may be displayed including the time required for adjustment control.

  In this embodiment, the end time of each job is displayed on the operation display device 600. However, for example, a configuration in which the end time of each job is displayed on an external computer 905 is also possible. In this case, when a display instruction is input from the external computer 905, the CPU 901 performs control to display the end time of each job on the external computer 905. Further, according to the flowchart of FIG. 8, the CPU 901 obtains both the longest time and the shortest time for each job in response to a display instruction input by the user. However, when the first mode is selected as the display mode, the CPU 901 can be configured to obtain only the shortest time for each job. Similarly, when the second mode is selected as the display mode, the CPU 901 can obtain only the longest time for each job.
