System and method for detecting a document trailing edge exiting feeder

A method of detecting a document in a system for feeding and transporting documents, the document having a leading edge and a trailing edge, the system including a feeder stage including a feeder and a separator for receiving a document therebetween and gripping the document with a first grip, and 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, the method comprising:

• detecting an acceleration of the accelerator idler indicating when the document trailing edge exits the feeder and separator.

The method 12 further comprising:

• after detecting the acceleration of the accelerator idler, performing an operation after the document trailing edge has exited the feeder and separator.
