PAPER FEED
B079/B082 6-70 SM
6.11.4 PAPER LIFT
The paper size switch [A] detects when
the paper tray [B] is set in the machine,
and the tray lift motor [C] rotates, and
the coupling gear [D] on the tray lift
motor engages the pin [E] on the lift
arm shaft [F]. Then the tray lift arm [G]
lifts the tray bottom plate [H].
When the paper tray is set in the machine,
the pick-up roller [I] lowers. When the top
sheet of paper reaches the proper height
for paper feed, the paper pushes up the
pick-up roller, and the actuator [J] on the
pick-up roller supporter activates the
paper height sensor [K] to stop the tray lift
motor.
After several paper feed cycles, the paper
level gradually lowers and the paper
height sensor is de-activated. The tray lift
motor turns on again until this sensor is
activated again.
When the paper tray is removed from the
machine, the tray lift motor coupling gear
disengages the pin on the lift arm shaft,
and the tray bottom plate then drops
under its own weight.
