Abstract
A sheet from the top of a stack of media, and is driven by a reversible electric motor operated in a forward direction to drive a feed roll and nudger roll; and operated in a reverse direction to drive a cam profiled to raise and lower the nudger roll. One-way clutched gears may be provided to restrict rotation of the feed roll and the nudger roll when the motor is operated in a reverse direction; and to restrict rotation of the cam when the motor is operated in a forward direction. A rotary cam may be profiled to allow for the reciprocating movement of the nudger roll from a down position in which the nudger roll contacts the top of the stack of media to an up position in which the distance between the nudger roll and the top of the stack of media is suitable for loading media onto the stack of media.
