6.9.5 PAPER HEIGHT DETECTION – TRAYS 1 & 2
[A]
Two paper height sensors, working in combination, detect the amount of paper in
the tray.
When the amount of paper decreases, the bottom plate pressure lever moves up
and the actuator [A] (on the pressure lever drive shaft) rotates.

6.9.6 PAPER END DETECTION – TRAYS 1 & 2
If there is some paper in the paper tray, the paper stack raises the paper end feeler
and the paper end sensor deactivates.
When the paper tray runs out of paper, the paper end feeler drops into the cutout in
the tray bottom plate, and this activates the paper end sensor.
