PAPER LIFT MECHANISM
B542 8 SM
When the paper tray is placed in the machine, the pick-up roller [A] 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 [B] on the pick-up roller supporter activates
the lift sensor [C] to stop the tray lift motor.
After several paper feed cycles, the paper level gradually lowers and the lift 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
disengages the pin on the lift arm shaft, and the tray bottom plate then drops under
its own weight.
