as shown the next piece is fed from the feeder into the transport 31 this process continues until the pre determined page set quantity is reached another mode of operation is where the transport 31 holds the first page of a set waiting for the subsequent pages for that set to be delivered to the transport 31 and accumulated once the accumulated set is complete it is delivered to a downstream device 45 an auxiliary input 35 having transport belts 47 u2032 driven by rollers 48 u2032 of the transport 31 is designed to accept another upstream device 46 such as any one of the following a manual feed tray universal friction or vacuum feeder sheet feeder or 1 up or 2 up continuous forms processor as shown in u s pat no 5 887 864 filed sep 29 1999 documents sheets are fed from the upstream device 46 into the input of the transport via round belts 47 and held at the transport dump rollers 48 the cpu 30 can be set to a predetermined page sheet quantity a set either directly by the user or automatically via an integrated omr bcr or ocr reading system a page set can be either.
