A document handler 1 for recirculating either simplex or duplex original document sheets, for precollation copying. Simplex or duplex documents are fed from their loading and restacking tray 2 to the copier platen 3 for exposure. Simplex documents are returned directly to the tray 2 through the inverting path 4. However, duplex documents may be returned to the tray 2 through non-inverting path 5 comprising auxiliary tray 6, where documents individually inserted therein by gate (deflector) 7 in its down position are reversed by resilient end stop 8 and then fed back out by lowering flexible vane paddle wheel feeder 9, with gate 7 now in its illustrated up position. The auxiliary tray 6 is located generally horizontally in the space between the tray 2 and the return flight of the platen document transport belt 10. Both simplex and duplex documents are restacked in tray 2 with the assistance of a restack in tray 2 with the assistance of restack vacuum transport belt 11, which is upwardly pivotal to provide unrestricted document sheet set loading into tray 2.
