The paper series setting mode is switched to the normal mode when the paper series setting process is completed.

  When the operation mode is set to the paper series setting mode, the paper series discriminating unit 11 a instructs the reading unit 12 to detect the size of the paper set in the reading unit 12 and is given from the reading unit 12. Based on the size of the paper in the main scanning direction and the sub-scanning direction, the paper series of the paper is determined. Based on the determination result of the paper series determination unit 11a, the setting processing unit 11b selectively uses a plurality of setting data stored in the storage unit 16 so as to switch various setting states such as a print magnification related to the paper series. It has become.

  Hereinafter, the processing operations of the paper series discriminating unit 11a and the setting processing unit 11b will be described in detail with reference to FIG.

  In step S1 of FIG. 3, the operation mode is switched to the paper series setting mode, and the paper of the paper series to be used after switching is set by the user on the document tray 36 of the reading unit 12, and the reading button or the like of the operation unit 15 is operated. Then, the document is passed through the conveyance path 37 by the reading unit 12, and the size of the document in the main scanning direction and the sub scanning direction is read. At this time, the size may be detected by placing a sheet on the document placing glass 39.

  In the subsequent step S3, the paper series discriminating unit 11a discriminates the paper series (in this embodiment, discrimination between A4 series and letter series). Specifically, the main scanning direction and the sub scanning direction size values of the A4 series and letter series sizes of paper are registered in advance in the storage unit 16 and the like, and the main scanning direction of the paper detected by the reading unit 12 is registered. By determining which paper size registered in the storage unit 16 or the like corresponds to the size in the sub-scanning direction, the paper series of the paper is determined.

  For example, when the detected size of the paper in the main scanning direction is 210 mm and the size in the sub-scanning direction is 297 mm, it is determined that the paper is A4 paper and the paper series to be used is A4 series. If the detected size of the paper in the main scanning direction is 257 mm and the size in the sub-scanning direction is 364 mm, it is determined that the paper is B4 paper and the paper series used is the A4 series. On the other hand, when the detected size of the paper in the main scanning direction is 216 mm and the size in the sub-scanning direction is 297 mm, it is determined that the paper is letter paper and the paper series to be used is letter series. If the detected size of the paper in the main scanning direction is 216 mm and the size in the sub-scanning direction is 356 mm, it is determined that the paper is a legal paper and the paper series used is a letter series.

  If it is determined in step S2 that the paper series to be switched to is an A4 series, the process proceeds to steps S3 to S5. On the other hand, if it is determined to be a letter series, the process proceeds to steps S6 to S8. The setting processing by the setting processing unit 11b is performed using the setting data corresponding to each paper series registered in No. 12.

  In step S3, when a paper other than the A4 series is set in the paper cassette of the paper cassette unit 42, the cassette in which the paper other than the A4 series is set is excluded as a destination for the printing paper. Only cassettes loaded with A4 paper (A3, B4, A4, a5, A5R, A6, F4) are set and registered.

  In step S4, setting data (50%, 70%, 81%, 86%, 100%, 115%, 122%) regarding originals of different paper sizes in the A4 series, so-called fixed magnification when performing reduction copying between papers. , 141%, 200% magnification data) is read from the storage unit 12 and set and registered as a fixed magnification to be used thereafter.

  In step S5, A4 series determination criterion data used for determining the recording paper size based on the width of the data image when the document data received by facsimile is recorded is read from the storage unit 12, and the determination criterion data is determined. Is registered as

  On the other hand, in step S6, when a non-letter paper is set in the paper cassette of the paper cassette unit 42, the cassette in which the non-letter paper is set is excluded as a destination for printing paper. Thus, only cassettes on which letter series (Ledger, Letter, Legal, H-letter R, Executive) are set are registered.

  In step S7, original data of different paper sizes in the letter series, setting data relating to so-called fixed magnification when performing reduction copy between papers (50%, 64%, 78%, 100%, 129%, 200% magnification data) ) Is read from the storage unit 12, and set and registered as a fixed magnification to be used thereafter.

  In step S8, the letter reference criterion data used to determine the paper size for recording based on the width of the data image when the document data received by facsimile is recorded is read from the storage unit 12 to determine the criterion data. Is registered as

  As described above, according to the present embodiment, the paper series of the paper to be used is automatically determined based on the paper size detected by the reading unit 12, and printing related to the paper series is performed based on the determination result. Since the setting state such as the magnification is automatically switched, it is possible to omit a complicated setting state switching operation associated with the switching of the paper series to be used.

  In particular, in the present embodiment, the fixed magnification is switched when the reduced copy is performed between different paper sizes required when the paper series is switched between the A4 series and the letter series, and the width of the received factory data is set. Since the switching of the determination reference data used for determining the recording paper size based on this and the switching of the paper cassette from which the printing paper is taken out are automatically performed, the convenience is high.

  In addition, since the paper size is detected by the reading unit 12, manual input of the paper size is unnecessary, which is convenient.

  Further, when the paper size is detected using the automatic document feeding unit 22 of the reading unit 12, it is not necessary to open and close the lid of the reading unit 12, which is more convenient.

  Note that the paper size can be detected using any equipment in the apparatus 1 that can detect the paper size. As another alternative, for example, when the paper cassette has a paper size detection function, the paper series may be determined based on the detection result of the paper cassette. In this case, when the paper is set in the paper cassette, the paper size is automatically detected, the paper series is determined based on the detection result, and the setting state of the apparatus is automatically switched based on the paper series. This is convenient because there is no need to perform a special operation for detecting the paper size.
