Paper Feed
When the paper tray is set in the machine, the pick-up roller [F] 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 on the pick-up roller supporter activates the paper lift sensor [G] 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.
6.11.5 TRAY LOCK MECHANISM
This machine has a tray lock mechanism.
The lock at the front prevents the tray from coming out of the machine during transporting or
shipping. When you pull the handle [A], the lock lever [B] is lowered. As a result, you can pull
out the tray.
