[5] OPERATIONAL DESCRIPTION MX-LCX2 Service Manual 1. Lift operation When the main unit is turned ON, if the tray is at the lower limit position (lower limit sensor: LDD ON position), the lift motor is turned ON to lift the tray. When the paper presence/empty sensor (LPED) is turned ON within 800 pulses of the encoder signal from start of lifting up the tray, the lift motor is turned OFF to stop the tray, and the paper feed solenoid is turned ON to move down the pickup roller.

Paper empty detection When the tray lifts and stops at the paper feed position and during paper feed operation, paper presence/empty is detected by the paper presence/empty sensor (LPED). When paper empty is detected in the tray during paper feeding, paper feeding is stopped.
