6.9.4 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 lift sensor [K] to stop the
tray lift motor.
After several paper feed cycles, the
paper level gradually lowers and the
paper lift 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.
