ABSTRACT:
Disclosed is a rotatably powered roller feed assembly for transporting documents from a stack in a forward feed direction toward utilization apparatus, a clockspring appropriately coupled to the feed assembly for rotatably powering the feed rollers in a direction opposite to the feed direction of rotation in order to drive documents out of, and to therefore clear, the nip point of the roller assembly. The reverse rotation is initiated at the end of each feed cycle by control means, including an optical sensor assembly responsive to a document exiting the nip point, interrupting the powering of the roller assembly in the feed direction.
