Paper lift
During feed, the lift plate raises the paper until the paper comes into contact with the pick roller. The sensor (lift plate
level) detects if the pick roller is sufficiently engaged with the paper. The motor (lift) controls the movement of the lift
plate. As the amount of paper lessens, the lift plate also continues to move up. When the tray is almost empty, the
actuator triggers the sensor (near empty).
