ABSTRACT:
In an electrophotographic copier having a given paper travel path from supply to exit, apparatus to enable the copier to automatically make two-sided copies. An auxiliary tray is positioned to selectively receive copy sheets from the exit hopper during the two-sided copying mode of operation. The tray is pivotable about an axis located just above the primary sheet supply. When it is desired to accomplish two-sided copying, sheets upon which first-side copy have been made are directed into the auxiliary tray with the first-side copy face of the sheets oriented opposite to the original orientation in the primary supply. The tray is then pivoted so that it overlies the primary sheet supply. The sheets in the tray may then be fed by the primary feed mechanism to have the second-side copy made thereon in proper registration.
