Here are some rules to follow for cleaning rollers and sensors.
Roller Cleaning
- Clean rollers with a dry cloth.
- Try to avoid touching the surfaces of the rollers with bare hands.
Sensor Cleaning
- Clean sensors with a blower brush. Do not use cloth or tissue paper.
- Most of the sensors are below holes in plates, so you may not be able to see them.
- Insert the tip of the blower brush into the hole and squeeze it to blow any paper dust off the sensor.
