MX-LCX3 [5] OPERATIONAL DESCRIPTION Service Manual 1. Lift operation B. Lowering operation by paper empty detection or pressing the tray SW A. Lifting by insertion of the tray When insertion of the tray is detected, the tray is locked by the tray lock solenoid so that the tray cannot be pulled out. When tray lock is settled by turning ON the tray lock sensor (LTLD), the lift motor is turned ON to lift the tray.
PAGE 8
C. Lowering operation by paper supply If the tray is pulled out when it is at the paper supply position, the tray lock solenoid keep the lock released. When the tray is pulled out, the tray LED turns OFF. When the paper front surface sensor (LPUD) is turned ON for 2sec while the tray is pulled out, the lift motor is turned ON to lower the tray. When the paper front surface sensor (LPUD) is turned OFF while the tray is lowered, the lift motor is turned OFF to stop the tray.
