Description

ABSTRACT:
A registration mechanism registers document sheets on a copier platen at an edge of the platen surface. The mechanism includes a unique gate member that moves relative to the platen edge to either register a document sheet or to permit the sheet to be driven past the edge and over a sheet deflector. For duplex copying, the deflector can be raised to guide the leading edge of the sheet over the platen edge as the sheet is returned to the platen for copying a second side of the sheet.
