Abstract: A document processing system includes a feeder stage, a transport stage, and a retractable mechanism cooperating with a portion of the document track. An assertable member is arranged with respect to the document track such that assertion of the member causes retraction of the opposed track walls in the cooperating portion of the document track by retracting a first base member from a second base member. An imaging assembly is composed of an imaging device and an image glass. The image glass is positioned as one side of the document track at the retractable mechanism. In the retracted state, the imaging assembly is retracted to provide access to the imaging device and the document track.
