ABSTRACT:
A document feeder system, interfaced with a copier system having, inter alia, a semi-automatic document feeder (SADF), an automatic document feeder (ADF) a document queue, and an associated logic control system that allows the suspending of a prior task being run on either of the foregoing document feeders and the commencing of a subsequent or urgent task on any one of the other foregoing document feeders immediately thereafter. Thus, when an urgent task operator selects a feeder suspending/commencing mode button, a single control panel is instantly made available so that the urgent task copy quantity and feature selections can be made. After the foregoing is accomplished, the single copying of the prior task original document on the document viewing glass is completed and the document stored in the document queue or ejected into a prior task exit pocket. Then the chosen urgent task feeder is enabled for feeding. In addition, the prior task status is retained for recall without having to reformat the single control panel. Accordingly, when the urgent task is completed, the urgent task operator de-selects the feeder suspending/commencing mode button thereby causing the copy quantity and feature selections of the prior task to be re-entered into the single control panel and the prior task to be immediately re-commenced without further operator intervention.
