When the machine detects that the paper tray has been placed in the machine
(detected by the connector at the rear of the tray), the lift motor [A] rotates and the
coupling gear [B] on the tray lift motor engages the pin [C] on the lift arm shaft [D].
The tray wires [E] are attached to the tray support rods [F, G]. When the lift motor
rotates clockwise, the tray wires [E] lift the tray support rods and the tray bottom
plate [H].
When the actuator on the tray support rod activates the tray lower limit sensor [I],
the tray lower limit condition is detected.
When drawing out the tray, the coupling gear [B] separates from the pin [C], so that
the tray bottom plate moves downward. Then the tray bottom plate drops. The
damper [J] lets the tray bottom plate drop slowly.
The paper end sensors [K] check whether there is paper on the tray.
The paper volume sensors [L] detect the amount of paper remaining in the tray by
monitoring the encoder, which detects the amount of lift motor rotation (this
mechanism is not present in the left side of the tandem tray).
