First of all I must say that I received the manual in just a few minutes after placing the order. The copy is well done and very readable. I will buy others soon... Thanks, Meyer

2.7.8 PAPER LIFT MECHANISM
When the tray is set in the machine, it detects this condition in several ways. The 1st tray detects by the tray set signal through the connector. The 2nd tray detects by paper size switch, and the 3rd tray detects by tray set switch.

When the machine detects that the 1st paper tray is set in the machine, the lift motor [A] rotates and the coupling gear [B] on the tray lift motor engages the pin [C] of the lift arm shaft [D]. The tray wires [E] are fixed in the slots [F] at the ends of the tray support rods [G, H]. When the lift motor rotates clockwise, the tray support rods and the tray bottom plate [I] move upward. The tray goes up until the top paper pushes up the pick-up roller and the lift sensor in the 1st feed unit is activated. When the actuator [K] on the front end of the right support rod [G] activates the paper near end sensor [J], the paper near end condition is detected. When drawing out the tray, the coupling gear [B] separate from the pin [C], so that the tray bottom plate move downward. The tray goes down until the actuator activates the tray down sensor [L]. The damper [M] lets the tray bottom plate drop down slowly. The paper sensor for the right tray [N] checks that there are sheets of paper in right tandem tray. If the machine determines that there are sheets of paper not using the right tray paper sensor, it needs the bottom plate to go upward toward the paper end sensor. The tandem tray capacity is 1,550 sheets, so it needs a long time to check. Therefore, the right tray paper sensor is necessary.
