Abstract
According to aspects illustrated herein, a printmaking device, a method, and a system for reducing process direction errors of a sheet in a registration device is provided herein. The printmaking device includes a feed path, a printing module, and a sheet registration system. The sheet registration system is along the feed path and includes at least one trail edge sensor, a registration controller, and at least one pair of registration nips. The feed path moves a first side of the sheet in a process direction. The registration controller registers the first side of the sheet by: measuring and correcting a first skew error of the sheet; measuring and correcting a first arrival time of the trail edge of the sheet to determine a first process direction position of the sheet; and delivering the first side of the adjusted sheet at a first predefined delivery time.
