Disclosed is a friction feeder image offset solution for document sheet feeders employing friction drive rolls often used in electrophotographic printing machines. A friction document feeder, whether friction-retard, active-retard, or semi-active retard, will offset poorly adhered images such as images written in pencil. The feed roll or belt, when driving the document, drives with sufficient friction and pressure to transfer a portion of the image material (pencil lead in this case) to the feed roll. On the subsequent feed roll revolution, the same friction and pressure transfers a portion of the offset image back to the document substrate as a "ghost" image.
