When the tray lift motor turns on, the pick-up solenoid [A] activates to lower
the pick-up roller [B]. When the top sheet of paper reaches the proper height
for paper feed, the paper pushes up the pick-up roller and the actuator [C] on
the pick-up roller supporter activates the paper upper limit sensor [D] to stop
the tray lift motor.
After several paper feed cycles, the paper level gradually lowers and the
upper limit sensor is de-activated. The tray lift motor turns on again until this
sensor is activated again.
When the tray is drawn out of the machine, the tray lift motor coupling gear
[E] disengages the pin [F] of the lift arm shaft, and the tray bottom plate [G]
then drops under its own weight.
