Tray lift
When the right tray is set, the tray set switch on the rear plate turns ON, and the tray lift motor starts rotating. Simultaneously, the remaining paper sensor performs a pulse count to determine the amount of paper in the tray.
The tray lift motor and rotation shaft are joined by a coupling, so that when the rotation shaft rotates, the tray bottom plate rises. The tray bottom plate rises until the actuator turns OFF the upper limit sensor (the sensor is blocked). If there is paper, lifting stops. If there is no paper, the tray bottom plate descends.
- After the right tray is set, if the upper limit sensor is OFF, it will turn ON. The tray descends until the lower limit sensor turns OFF. After stopping temporarily, the tray bottom plate then rises to the upper limit.

Tray descent
If there is no paper when the upper limit operation is completed, the tray bottom plate descends until the lower limit sensor turns OFF (the sensor is blocked). The tray bottom plate will descend if paper end is detected during paper transport.
