Abstract

Electronic reprographic and electronic printing systems having image output terminals (IOT's) are capable of job streaming for increased productivity, where one output job is begun immediately upon completion of the previous job without operator intervention. In general, the jobs are maintained in a print queue, awaiting output by the IOT. While job streaming enables greater output rates, it presents a special set of problems when using ordered stock sets (i.e., precut tab stock) for the output job. When a job using ordered stock is aborted, it is necessary to purge the unfed portion of the stock set in order to have a complete set available for the next job that requires the ordered stock. If the partial ordered stock set were not purged from the feed area, subsequent jobs using that stock would not begin with an integral ordered stock set.

Electronic reprographic and electronic printing systems having image output terminals (IOT's) are capable of job streaming for increased productivity, where one output job is begun immediately upon completion of the previous job without operator intervention. In general, the jobs are maintained in a print queue, awaiting output by the IOT. While job streaming enables greater output rates, it presents a special set of problems when using ordered stock sets (i.e., precut tab stock) for the output job. When a job using ordered stock is aborted, it is necessary to purge the unfed portion of the stock set in order to have a complete set available for the next job that requires the ordered stock. If the partial ordered stock set were not purged from the feed area, subsequent jobs using that stock would not begin with an integral ordered stock set.

Accordingly, the present invention implements a check for ordered stock set integrity upon job abortion, within the IOT controller. More specifically, whenever an ordered stock job is aborted mid-set, not at a set boundary, the controller prevents the ordered stock tray from subsequent use until the unfed portion of the ordered stock set is purged. The actual purging operation is implemented by instructing an operator to manually purge the unfed partial set,...
