ABSTRACT:
In a document copying apparatus of the type having (a) a "spot" color capability, (b) an automatic document feeder and (c) a multibin sorter, the copier's logic and control unit is programmed to automatically switch from a "recirculation" mode, to which it defaults unless instructed otherwise, to a "sorter" mode in response to a signal indicating that at least one page of a multipage document being copied requires that a copy sheet be presented twice to an image transfer station to complete the copying thereof. As a result of this automatic change in operating modes, fewer "skip" frames need be introduced during the copying operation, thereby enabling the copier to produce multiple collated copies of the multipage document more efficiently.
