A printing system having an electronic sub system loaded with control software which controls scanning, image storing and the printing operations of the printing system. The control software schedules the bandwidth of disk storage and swaps images from a storage disk to a memory so that a desired image will be in memory when the printing of that image is requested. The system utilizes resource management and/or memory management software to realize improved job turn around time and to reduce pitch skips.

In a system for detecting and signaling the approximate size of a set, stack or job of document sheets, especially for a recirculating type automatic document feeder with a document set stacking and feeding tray for a copier or other document imaging system, in which an electromechanical set separator system provides rough initial stack height and therefore set size or document number estimation signals from the position of the set separator arm on the stack, and in which there is also a counter for counting the number of document sheets fed out from the tray; the advance estimation of the number of documents to be fed to be imaged is significantly improved by dynamically comparing the count of the number of document sheets fed out from the tray at and with the transition in the set size estimation signal from the set separator system.
