ABSTRACT:
Apparatus for producing duplex or simplex collated copies from duplex and simplex originals comprising a copier having a duplexing section with two transfer stations separated by a copy-sheet inverter. A document feeding section circulates and recirculates original sheets, one-after-another, for producing sets of copies in page-sequential order. The document feeder is provided with a single hopper for receiving and maintaining the originals in their usual page sequence or order so that no preparation (i.e., special arrangement) of an original is necessary prior or subsequent to copying for making collated copies. The duplexing section requires only a single fuser that is positioned so that the copy sheets pass through both transfer stations before entering the fuser, thus permitting transfer of images under similar conditions in both transfer stations.
