Abstract

A system that provides for automatic duplex (2nd side) copy~- ing on two or more different sizes of copy sheets without having to manually reset side guides of the duplex tray when the size of copy sheets being fed is changed (i. e, when the size of paper in the input sheet feed tray is changed or a selection is made between two or more input sheet trays containing different sized sheets).

SYSTE2~1 FOR AUTOMATICALLY ADJUSTABLE SIDE GUIDES (Cont~d)

herein i~the concept of having the side guides of the acceptor or duplex tray automatically adjust the spacing therebetween before feeding from this duplex tray, so as to provide the proper paper alignment and position.

This may be accomplished by electrically sensing a side
guide setting of the input sheet tray from which the first
side copies are being made and using this sensing signal
to control a conventional motor and lead screw arrange~
ment or the like to move the duplex tray side guides
when the machine logic is in the duplex mode, but not
otherwise, so that in a simplex mode the duplex tray
may be used as an auxiliary feed tray.
