US Patent 7418159 Document processing system with track allowing selective reprocessing of documents

A document processing system includes a feeder stage and a transport stage. The document track assembly includes at least one feedback section forming a document return path that extends from an exit point at one part of the document track to a reentry point at another part of the document track further back, upstream. The document track assembly is configured to allow the selective rerouting of a document through the document return path to make a repeat pass through a processing station located between the document track reentry point and the document track exit point. This provides increased reliability in document processing, particularly when processing involves checks, obtaining electronic images of checks, and check truncation.
