[2] Mechanisms
*1 Paper lift-up
a) Hoisting of up/down plate
The up/down plate is lifted up by up/down wires. When the paper tray is loaded, the up drive motor 3 (M21)
rotates to wind the up/down wires around the drive pulleys and consequently the plate moves up. When
the tray upper limit PS3 (PS22) detects the actuator of the plate that has moved up, the up drive motor
3 (M21) stops.
