Abstract
A sheet advance device has a transport device for transporting a stack of sheets in a first direction, a feed finger located in the path of the stack of sheets for contacting the stack of sheets, a sensor for detecting a movement of the feed finger; and an externally-located adjustment device for positioning of the feed finger. Also provided is a method for advancing sheets on a transport device comprising the steps of moving a stack of sheets on the transport device against a feed finger so as to move the feed finger in a first direction, sensing the movement of the feed finger so as to generate a stop signal, stopping the transport device as a function of the stop signal, removing individual sheets from the stack of sheets so as to reduce the stack in a direction opposite the first direction and move the feed finger opposite the first direction, moving the transport device in the first direction after the removing step, and adjusting a position of the feed finger through an externally-located adjustment device.
