9.2.1 Before You Begin
To clean the rollers and sensors, follow the instructions below:
Roller Cleaning
• Clean the rollers with a dry cloth.
• Try to avoid touching the surfaces of the rollers with bare hands.
Sensor Cleaning
• Clean the 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.
