ABSTRACT:
A multiple-function printing device provides for picking pages from a stack of sheets in an input feeder for roller-driven movement along a first path through a printing station to an output, and for picking pages from a stack of documents in an input feeder for roller-driven movement along a second path through a scanning station to an output, with at least a portion of the first and second paths being commonly shared, and with common mechanisms being used for various steps such as for picking, providing roller-driven movement through the processing stations, and for actuating a pressure plate in the input feeders. A document guide in a document scanning mode of operation is pivoted into a lowered position generally parallel to the print station platen to constrain and contain the top and bottom of any curled document exiting from the scan station into an output roller nip so as to prevent an incipient paper jam. Prior to a printing mode of operation on a paper sheet, the document guide is pivoted about 100.degree. so that it does not interfere with an incoming print cartridge.
