ABSTRACT:
A document transport system for transporting documents of varying thicknesses along a document path comprising a document drive assembly forming one side of the document path, an idler roller assembly forming an opposite side of the document path, the document drive assembly including a moving belt adapted to engage each document and move each document along the document path, the idler roller assembly including a plurality of idler rollers adapted to move automatically and manually, alternately, between a first position contacting the moving belt when no documents are present in the document path and contacting the documents when present in the document path, and a second position out of contact with the moving belt or the documents, thereby forming a gap between the idler rollers and the moving belt, the idler rollers being connected by a lost motion connection to an idler release lever, whereby the idler release lever remains stationary when the idler rollers move automatically between the first position and the second position, and whereby actuation of the idler release lever causes movement of the idler rollers from the first position to the second position to permit the clearance of jams in the document path.
