Paper Near End/End Detection
There are four sensors in tray 1: the two near end sensors [B] [E], the end sensor [C] and the paper width
sensor [A].
Near-end detection
Two near end sensors detect the amount of paper in the tray.
When the quantity of paper decreases, the bottom-plate-pressure lever moves up and the actuator [F] (on
the pressure-lever drive shaft) turns.

End detection
When the paper tray is empty, the actuator [D] goes into the end sensor. The sensor detects paper end.
