ABSTRACT:
An improved dual mode document handler for a copier, in which documents may be either loaded into a document stacking tray overlying the copier imaging station platen and recirculatively fed thereto for pre-collation (RDH) copying, or, alternatively, fed into a semi-automatic document handling (SADH) path slot adjacent thereto on top of the document handler, conveniently face up and feeding downwardly therein for gravity assistance in loading documents into the slot. This SADH input path non-interferingly crosses over (intersects) the document restacking return path to the tray of RDH path. The SADH input path merges into the recirculating document path just after the stacking tray feeder/separator output and prior to the side registration feeder and turn baffles feeding to the copier platen (at a point in common with the duplex document inverting return path) to commonly utilize the same feeder and path, thereby providing alternative SADH/RDH document feeding at little additional cost in the same integral low cost document handler, and with a desirable SADH document input location, even though the document handler feeds and returns documents from the same side of the tray and platen.
