Drive from the reversible LCT motor [A] is transmitted through a worm gear
[B] to the drive pulley shaft [C]. The tray wires [D] are fixed in the slots [E] at
the ends of the tray support rods [F] and [G].
When the LCT motor rotates forward and the drive pulley shaft [C] turns
counterclockwise, the tray support rods and the tray bottom plate [H] move
upward. The tray goes up until the top paper pushes up the pick-up roller and
the lift sensor in the third feed unit is activated.
The paper near end sensor [I] detects the paper near end condition when it is
activated by the actuator [J] on the rear end of the right support rod [G].
To lower the tray bottom plate [H], the LCT motor rotates in reverse and the
drive pulley shaft [C] turns clockwise, the tray support rods and the tray
bottom plate move downward. The tray goes down until the tray down sensor
[K] is activated by the actuator.
