Zusammenfassung:A pre-registration system increases the latitude of present active registration systems by decreasing the lateral offset of sheets before they reach the active registration system. This is accomplished by pivoting and translating a sheet supply elevator with stepper motors in conjunction with sensing a lateral edge of sheets in order to direct the sheets to the proper lateral position to be fed into the active registration system with a minimum of lateral offset.
