2.5 PAPER END DETECTION

[A]

[B]

B832D933.WMF

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.
