Abstract
A sheet post processing apparatus includes a plurality of movable a post-processing device for effecting a predetermined post-processing for a set of sheets; malfunction detector for detecting malfunction for each of the post-processing device; a controller, responsive to the malfunction detector, for controlling the post-processing device to place, at a position where the post-processing device is to be placed if the malfunction did not occur, another one of the post-processing device free of the malfunction.
Claims11
A sheet post processing apparatus comprising:
- a plurality of movable post-processing means for effecting a predetermined post-processing for a set of sheets;
- malfunction detecting means for detecting malfunction for each of said post-processing means;
- control means, responsive to said malfunction detecting means, for controlling said post-processing means to place, at a position where said post-processing means is to be placed if the malfunction did not occur, another one of said post-processing means free of the malfunction.
An image forming apparatus comprising:
- image forming means;
- sheet stacking means for stacking sheets after formation of images by said image forming means;
- a plurality of movable post-processing means for effecting a predetermined post-processing for the sheets stacked on said sheet stacking means;
