ABSTRACT:
A copy machine schedules a copy sheet for being fed by a copy sheet feed system from a supply to a transfer station to have an image copied from an original document to the copy sheet after that original document is scheduled for being imaged by an imaging system. Usually, the scheduling of the copy sheet feed system is delayed until the following pitch, and thus the scheduling of the copy sheet feed system occurs in a different pitch than the scheduling of the imaging system for a particular document. This delay permits the end-of-set signal to be generated if that document is the last document in a stack of documents to be copied prior to scheduling the copy sheet which is to receive a copy of the image contained on that last document. Thus, the control hierarchy of the copy machine is able to use the knowledge that a document is a last document in a set of documents to accurately control components of the copy machine (e.g., to select a proper type of copy sheet and/or offset copy sheet output) without skipping pitches or precounting the documents in the stack.
