ABSTRACT:
To prevent mixture of papers discharged by an image forming apparatus when sheet post-treatment equipment that executes post-treatment on papers discharged by the image forming apparatus post-treats papers supplied directly to the sheet post-treatment equipment by a user. When an off-line mode is selected via an operation panel of the sheet post-treatment equipment, a sheet post-treatment equipment controller notifies an engine controller of the image forming apparatus that this mode has been selected. The engine controller indicates on an operation panel that the off-line mode has been selected, and disables an image formation start instruction key.
