Paper feed tray is driven by wires. When the
paper tray is loaded, the tray up drive motor 3
(M18) rotates to wind the wires around the
drive pulleys and consequently the up/down
plate in the tray moves up. When the tray
upper limit PS/3 (PS14) detects the actuator
of the roller that has been moved up by paper,
the tray up drive motor 3 (M18) stops.
