2.4 REMAINING PAPER DETECTION

The amount of paper remaining in the tray is detected by the three paper height

photo-interrupter sensors on the left rail as the bottom plate rises. Five states,

determined by the position of the actuator are possible.

1. With the actuator [A] below paper height sensor 1 [B], no sensor is actuated

and the display indicates 100%.

2. When the actuator passes paper height sensor 1 [B] , the display indicates 75%

of the paper supply remaining.

3. When the actuator passes paper height sensor 2 [C], the display indicates 50%

of the paper supply remaining.

4. When the actuator passes paper height sensor 3 [D], the display indicates 25%

of the paper supply remaining.

NOTE: When the actuator enters the gap of the near end sensor [E], the

machine signals near end.

Finally, when the last sheet feeds, the paper end sensor signals that the tray is

empty. (☛2.5)
