Tray lift motor on, pick-up solenoid [A] on, pick-up roller [B] lowers.
When the top sheet of paper reaches the proper paper feed level, actuator [C] on
the pick-up roller support [D] activates the tray lift sensor [E], and the lift motor
stops.
After several paper feeds, the paper level gradually lowers and the lift sensor de-
activates. Next, the lift motor turns on again until the lift sensor once again
activates.
When the tray is pulled out of the feed unit, coupling [F] disengages pin [G] on
shaft [H], and the tray bottom plate [I] drops by its own weight.
