Abstract

It is known to provide an out of staples or low staple supply signal display to the operator of a copier or printer. It is particularly desirable to provide an indication in advance that the machine finisher is about to run out of staples or stitcher wire so that the machine does not stop stapling in the middle of a job or production run.

It is known to provide an out of staples or low staple supply signal display to the operator of a copier or printer. It is particularly desirable to provide an indication in advance that the machine finisher is about to run out of staples or stitcher wire so that the machine does not stop stapling in the middle of a job or production run.

By way of background, there is noted Xerox Corporation U.S. Patent No. 3,690,537 issued September 12, 1972; and also U.S. 3,685,712, with an illustrated operator machine display of "add staples". Also, US. 4,516,713 entitled "Low Wire Sensor" for a wire stapler supply indicator, and Xerox Corporation U.S. 4,187,969, issued February 12,1980, which teaches sensing and providing an electrical signal in response to the staples running low, i.e. approaching the end of the staple stick.

Suggested here is for the copier or printer controller to keep track of the number of staples or stitcher wire segments used, calculate and the number remaining, and signal that well in advance.

By comparing the number of staples or stitcher wire segments available to the known number of sets in the run in the copiedprinter controller (and the set thickness in the case of a variable staple length stitcher as opposed to pre- formed staples), the controller can determine whether there will be sufficient staples left to complete the next job and signal the machine to stop for reloading the staples, rather than wait to run out in the middle of the job when the machine is unattended due to the departure of the operator during the job- printing run. The present system would signal the operator beforehand that there are insufficient staples fo...
