Cleaning the Ultrasonic Sensors
If the scanner sometimes fails to detect multi-feed via ultrasonic
sensors, it is possible that paper dust or dirt may be
accumulated on the surface of the ultrasonic sensors. Please
follow these steps to clean the sensors.
1.
Press the ADF release button. Open the front door.
2.
Wet a clean cloth with some isopropyl alcohol. (95%) If
accidentally use too much alcohol, be sure to wring out the
damp cloth.
3.
Gently wipe the dirt and dust off the surface of the ultrasonic
sensors.
Note:
If it is difficult to clean, use a cotton swab.
