ABSTRACT:
A sheet stacking duplex tray includes a movable finger which separates a first group of sheets under the finger from a second group of sheets above the finger. Sheets which have been copied on only one side are fed to a copy station from the bottom of the tray for second-side copying, as other sheets which have been copied on only one side are fed to the tray, to reside on top of the finger. When all sheets of the first group have been fed, the finger gravity-falls through an opening in the tray. A detector senses this finger movement, and a solenoid then resets the finger to rest on the top sheet of the sheets then in the tray.
