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 secured in the slots [E] at the ends
of the tray support rods [F] and [G].
When the LCT motor turns 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 of the paper stack pushes up the pick-up roller, and
rd
the 3
tray lift sensor 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 reverses 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 [J].
