Abstract

A convenience copier has a photoconductor (PC) drum for carrying latent images to be developed on copy sheets received from one of a plurality of copy sheet supplies and transferring same at a transfer (XFR) station. Copy sheets then proceed along the copy sheet transport path indicated by the dotted line to either an exit tray or a collator. One of the problems associated with such a machine is the rapid removal of copy sheets by an operator upon a jam detection. This problem is particularly compounded in relatively long copy sheet transport paths. To facilitate such removal, a set of jam detection circuits are connected to a plurality of copy sheet sensors labeled sense 1 through sense 6, duplex sense and POD sense (not shown). The latter is to detect paper on the drum.
