Abstract
A document feeder with overlap protection that prevents the overlap of successive documents moving from a document stack and that utilizes a nudger. An independent motor selectively drives the nudger. Document edge detectors sense the location of documents at the nudger and at other locations fed from the document stack and send control signals to the independent motor so that a proper distance is maintained between successive documents. A document edge detector can be placed at various locations along the path of document travel.
