An operator of a printer may choose a maximum decomposition time for a page of a print job. Each page in the print job must fully decompose before the maximum decomposition time is reached. If a page does not fully decompose before the maximum decomposition time is reached, the print job may be terminated. In addition, a notification may be generated advising the operator that a page of the print job did not fully compose before the maximum decomposition time was reached. The establishment of maximum decomposition times helps to ensure that a single print job does not monopolize a printer or other output device.

Limiting decomposition time on a per page basis for output devices

A system for detecting and signaling the feeding of a complete set, stack or job of document sheets, especially for a recirculating type automatic document feeder for a copier or other document imaging system with a document restacking tray, in which normally an electromechanical sheet separator provides an end of set detection signal by mechanically operating each time the last sheet of the stack is fed. Here, the end of set detection and control signal is provided instead by a preset brief electrical signal from a non-mechanical optical no-sheet-present-in-tray detector for those documents sets having a sufficiently small number of document sheets such that all of the document sheets are temporarily in the document recirculation path after the last sheet of the set is fed out of the document tray on each circulation so that this optical sheet presence detector briefly signals that no document sheet is present in the tray, indicative that the last sheet of the small set was fed. This same preset maximum time period signal is used to automatically deactivate the regular electromechanical end of set detector for all further set circulations of that job to reduce wear and jam or set circulation miscount risks.
