Abstract
Methods and devices for moving media sheets through an image forming device. A sensor is positioned within an input area to determine a height of a media stack. When the media stack is full, a top-most sheet of the media stack is physically closer to the beginning point of the media path. When the media stack is depleted, the top-most sheet is positioned a further distance away from the beginning point. Movement of the media sheet is determined based on the height of the media stack. When the media stack is above a predetermined amount, the media sheet is moved according to a first algorithm. When the media stack is below the predetermined amount, the media sheet is moved according to a second algorithm.
