Abstract
A sheet processing apparatus of one aspect of the present invention includes an alignment unit configured to align sheets stacked on a stack tray, and perform. The sheet processing apparatus determines whether or not a part of sheets stacked on the stack tray has been removed from the stack tray. When it is determined that a part of sheets stacked on the stack tray has been removed from the stack tray, the sheet processing apparatus inhibits an alignment of the sheets using the alignment unit.
Claims12
A sheet processing apparatus comprising:
- a stacking control unit configured to control to stack sheets on a stack tray;
- an alignment unit configured to align sheets stacked on the stack tray;
- a determination unit configured to determine whether or not a part of sheets stacked on the stack tray has been removed from the stack tray;
- and
- a control unit configured to inhibit alignment by the alignment unit in a case where the determination unit determines that a part of sheets stacked on the stack tray has been removed from the stack tray.
A sheet processing apparatus comprising:
- a stacking control unit configured to control to stack sheets on a stack tray;
- an alignment unit configured to align sheets stacked on the stack tray;
- and
- a control unit configured to inhibit a process for alignment by the alignment unit, wherein
- when all of sheets stacked on the stack tray have been removed from the stack tray, the control unit cancels inhibition of the alignment.
A control method for a sheet processing apparatus that includes a stacking control unit configured to control to stack sheets on a stack tray and an alignment unit configured to align sheets stacked on the stack tray, the control method comprising steps of:
- determining whether or not a part of sheets stacked on the stack tray has been removed from the stack tray;
- and
- inhibiting alignment by the alignment unit in a case where it has been determined that a part of sheets stacked on the stack tray has been removed from the stack tray.
A computer-readable storage medium storing a program for causing a computer to execute steps of a control method for a sheet processing apparatus that includes a stacking control unit configured to control to stack sheets on a stack tray and an alignment unit configured to align sheets stacked on the stack tray, the control method comprising steps of:
- determining whether or not a part of sheets stacked on the stack tray has been removed from the stack tray;
- and
- inhibiting alignment by the alignment unit in a case where it has been determined that a part of sheets stacked on the stack tray has been removed from the stack tray.
