- the printing position on the front side and the printing position on the back side are shifted from each other in the paper transport path. More specifically, the front side photosensitive drum 12 F has the back side photosensitive drum 12 B Since it is more forward in the paper traveling direction, when printing on both sides, it is necessary to shift the timing of printing on the front and back sides of the paper. Therefore, in the case of double-sided printing, a delay unit 125 that delays the drive timing of the front side print control unit 123 by a predetermined time from the drive timing of the back side print control unit 124 is provided.

The reversing mechanism presence / absence flag is determined at the time of device startup according to the device configuration.
- the print processing unit 105 determines that there is no reversing mechanism based on the reversing mechanism presence / absence flag, the print processing unit 105 sends to the memory controller 110 the page data of the front side area in the memory 104 and the back side print control unit 124 (S113), and request that the page data of the back side area be output to the front side print control unit 123. I ask (S111).
- the page data for the front side is printed on the back side of the paper, and the page data for the back side is printed on the front side of the paper. To be done.
- the paper is in a state similar to the state in which the paper is reversed by the reversing mechanism of the post-processing machine 5, and the post-processing machine 5 cuts the paper in such a reversed state and generates a BTS switching force 6.
- the print processing unit 105 drives both the front side print control unit 123 and the back side print control unit 124 with respect to the main control unit 121 of the mechanical controller 120. Thus, a double-sided printing request is issued (S115).

- the post-processing machine 5 does not have a reversing mechanism, the paper cut by the post-processing machine 5 in units of pages is printed on the printed side (front side). ) Is on the top and is stacked on the BTS stacking force 6, so when the paper is removed from the BTS stacking force 6 and the printing side of the paper is on the top, the last page comes to the top and the page number is continuous. But the order is reversed.
- the print command from the host device is one-sided printing, but the print processing unit 105 needs to issue a two-sided printing request in order to drive the back side print control unit 124.
- the front side of the paper is output by outputting blank page data prepared in memory 104 to the front side print control section 123. Can be left blank.
- step S121 if the paper output destination is the main body scanner, or in step S122, the paper output destination is the post-processing machine, but If the processor has a reversing mechanism, the normal printing process is performed. That is, the print processing unit 105 requests the memory controller 110 to output the page data of the front surface area in the memory 104 to the front print control unit 123 (S 1 2 6) Further, a single-sided printing request is issued to the main controller 1 2 1 of the mechanical controller 1 20 so that only the front side print controller 1 2 3 is driven (S 1 2 7) .
