Abstract

This first-in, first-out (FIFO) duplex tray accommodates sheets of different width, without the need for three registration walls to maintain the stack of sheets in an orderly stack as sheets are fed into and out of the tray. This duplex tray is used with a xerographic copier where copy images are placed on one side of a sheet, the sheet is stacked in the tray, and the sheet is returned to the copier's transfer station for second-side copying. A separator finger (not shown) is provided to separate a lower stack of sheets of one characteristic (for example, side-one copies of page 1) from an upper stack of sheets of another characteristic (for example, side-one copies of page 3). These two stacks of sheet types comprise the stack of sheets within the FIFO tray. Fig. 1 is a side view. Fig. 2 is a top view.
