Paper Detection
Since the paper path from Tray 1/Duplex to the Registration Sensor and from
the paper tray to the Registration Sensor are different, the Registration
Sensor is provided with Actuators A and B.
■
Actuator A detects the sheet fed from Tray 1/Duplex.
■ Actuator B detects the sheet fed from the paper tray.
The movement of Actuator A does not affect Actuator B.
