Abstract:
A system for feeding and transporting documents, each document having a leading edge and a trailing edge, the system comprising:a feeder stage including a feeder and a separator for receiving a document therebetween and gripping the document with a first grip; a transport stage downstream of the feeder stage, the transport stage including an accelerator driver and an accelerator idler for receiving the document therebetween and gripping the document with a second grip that is less than the first grip such that when the document is simultaneously gripped by the feeder and separator and gripped by the accelerator driver and accelerator idler, the document slips at the accelerator driver until the document trailing edge exits the feeder and separator; a tachometer at the accelerator idler; and control logic configured to a detect an acceleration of the tachometer indicating when the document trailing edge exits the feeder and separator, and to provide an output signal.
