PAPER FEED
[D]
[B]
When the 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 paper feed
level, the paper pushes up the pick-up roller and the actuator [C] on the
pick-up roller supporter [D] activates the lift sensor [E] to stop the lift motor.
After several paper feeds, the paper level gradually lowers then the lift sensor
is de-activated and the lift motor turns on again until the lift sensor is
activated again.
When the tray is drawn out of the feed unit, the lift motor coupling gear [F]
disengages the pin [G] of the lift arm shaft [H], then the tray bottom plate [I]
drops.
