Abstract
A gate for allowing copy paper to pass at a selected one of a plurality of points in a copy cycle so that the leading edge of the copy paper mates with the leading edge of an image. The gate control mechanism includes a solenoid responsive to specific points in the copy cycle and to different sizes of copy paper such that the solenoid is actuated at different points in the copy cycle dependent upon the size of copy paper. The solenoid moves a gate arm which positions an interposer in a first position whereby it is struck by one of a plurality of tabs. The interposer is moved by the tab, causing a pivot shaft to rotate, thus releasing a pawl and allowing the gate shaft to rotate opening the gate.
