Abstract
A registration system for copy sheets uses a pair of drive rolls and a drive system for commonly driving both drive rolls. A differential drive mechanism is provided for changing the relative angular position of one of the rolls with respect to the other roll to deskew the copy sheet. A control system is supplied with inputs representative of the skew of the copy sheet and controls the differential drive mechanism to deskew the copy sheet. The system offers enhanced performance and reduced cost.
