3.3.7 Paper detection by the Regi Sensor

Since the paper path from the MPF/Duplex to the Regi Sensor and that from the Paper Tray to the Regi
Sensor are different, the Regi Sensor is provided with the Actuator A and Actuator B.
The Actuator A detects the sheet fed from the MPF/Duplex.
The Actuator B detects the sheet fed from the Paper Tray.
However, the movement of the Actuator A does not affect the Actuator B.
