Abstract
A document reproduction machine, such as a convenience copier, has an operator selected noncollated tray output and a collated output. An intermediate copy count, a transient copy count, and a document tracking indicator cooperate with decision logic to provide an automatic control for some copy overflows and error recovery control. For jam recovery, the transient count alters the intermediate count such that copies lost in a paper path are accounted for. Diverse modes of operation alter the timing of the jam detection circuits so as that one copy sensor is operative in any mode for precise jam detection. The modes also alter operation of the jam detection circuits so that one jam circuit operates in all modes. Collator to copy machine interlocks ensure no copy production occurs until the collator jam has been cleared. Upon a jam in the copy machine, local timing signals replace normal timing signals from the copy machine so that the collator can finish collating good copies and yet immediately stop the copy machine. Nonoverlapping of copy runs facilitate jam recovery.
