the transport via round belts 47 and held at the transport dump rollers 48 the cpu 30 can be set to a predetermined page 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 single page or multiple pages when accumulating in a downstream device 45 the transport 31 is emptied into the downstream device and the cpu 30 simultaneously initiates the next document from the upstream device 46 to be fed into the transport 31 this process continues until the pre determined page set quantity is reached when accumulating in the transport 31 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 from the upstream device 46 once the set is complete it is delivered to a downstream device 45 dual input is also enabled the transport 31 has two inputs the feeder input 49 and integrated auxiliary input 35 whereas documents from the feeder and an auxiliary upstream device 46 can be staged or merged in the transport 31 these inputs can be used integrally allowing documents to be merged in the transport 31 or downstream device 45 whereas documents are fed from the feeder 50 or upstream device 46 into the input of the transport 31 via round belts 47 and held at the transport dump rollers.
