<p>PROBLEM TO BE SOLVED: To continue post-processing even when jam occurs. SOLUTION: This sheet post-processor to receive discharged sheets from a sheet discharge part of an image forming device to staple them for every specified number, or to stack the sheets on a discharged sheet tray without stapling them is provided with a first, a second, and a third post processing parts 1, 2, 3 comprising combination of stapling mechanisms and discharged sheet trays. When paper jam occurs in either post-processing part 1, 2, 3, in a case where other post-processing parts 1, 2, 3 are usable, a jam condition is temporarily released, and sheet post-processing after that is conducted at the other post-processing parts 1, 2, 3 which are normal.</p> |
