Abstract
According to one embodiment, a post-processing apparatus includes a first sensor, a second sensor, and a control unit. The first sensor detects an object in a predetermined area in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus. The second sensor detects an object at a position closer to an opening in the area than the position of the first sensor with respect to the opening through which the sheet passes when the post-processed sheet is discharged from the area. When the second sensor detects an object before the first sensor detects the object, the control unit performs a predetermined process for preventing the occurrence of a failure.
Claims20
A post-processing apparatus, comprising:
- a first sensor that detects an object at a first position in a predetermined area in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus;
- a second sensor that detects the object at a second position closer to an opening in the predetermined area than the first position with respect to the opening through which the sheet passes when the post-processed sheet is discharged from the predetermined area;
- and
- a control unit that performs a predetermined process for preventing an occurrence of a failure when the second sensor detects the object before the first sensor detects the object.
A post-processing method, comprising:
- detecting an object at a first position in an area of a post-processing apparatus in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus;
- detecting the object at a second position closer than the first position to an opening in the area, the opening is an opening through which the sheet passes when the post-processed sheet is discharged from the area;
- and
- performing a predetermined process for preventing an occurrence of a failure when the object is detected at the second position before the object is detected at the first position.
A method of preventing failure during post-processing, comprising:
- detecting an object at a first position in an area of a post-processing apparatus in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus;
- detecting the object at a second position closer than the first position to an opening in the area, the opening is an opening through which the sheet passes when the post-processed sheet is discharged from the area;
- and
- stopping post-processing when the object is detected at the second position before the object is detected at the first position.
