Abstract

An automatic document feeding device including a pick motor coupled with a pick assembly, a deskew motor coupled with a deskew assembly, a sensor assembly coupled with a main media path and the deskew motor, and a feed motor coupled with a feed assembly. The deskew motor drives the deskew assembly, the deskew assembly deskewing the media sheet and moving the media sheet from the pick assembly to the feed assembly, the deskew assembly moving independently of the pick assembly and the feed assembly. The sensor assembly includes a plurality of sensors. The sensor assembly senses the media sheet moving along the main media path and sends at least one signal to a computer. The computer, based on the at least one signal, sends, an activation signal to at least one of the pick, deskew and feed motors and the first scanner.
