Media sheet input devices for use in an image forming apparatus

摘要

Assemblies and methods to move media sheets from a media stack within an image forming apparatus. These may include a pivoting arm with an attached roller that contacts the media stack and rotates to move a top-most sheet from the media stack. A clutch may be operatively connected to the arm for the arm to pivot in a first direction to maintain the roller positioned on a top of the media stack as the media stack is depleted and a height of the media stack is reduced. The clutch may also reduce movement of the arm in a second direction beyond a predetermined amount.
