5.9 PAPER END DETECTION
The paper end sensor [A] detects the top sheet of the paper in the tray by
monitoring the reflected light. When the paper tray runs out of paper, the paper end
sensor does not receive the reflected light due to the cutout [B]. Then, the tray lift
motor rotates backwards 2 seconds to drop the tray bottom plate.
