5.8 REMAINING PAPER DETECTION
The amount of paper remaining in the tray is detected by the three paper height
photointerrupter 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.
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.
