ABSTRACT:
A sheet registration system for a sheet handling device has a plurality of driven belts. Each belt is entrained about a driven roller and an idler roller. The driven rollers are fixedly mounted on a common drive shaft that is connected to a motor. The idler rollers each have a shaft and the idler shafts are coaxially aligned and parallel to the common drive shaft. Adjacent idler shafts are interconnected. The idler rollers are cantilevered about the common drive shaft and may be pivoted thereabout. The gravitational force on the cantilevered idler rollers provide the normal pressure on the belts to produce the frictional force necessary to acquire and register incoming sheets. Selective pivoting of the idler rollers in response to sheet media parameters inputted to a control panel by an end user automatically varies the normal pressure of the idler rollers and adjusts the frictional force of the belts.
