Cleaning the Paper Sensors
The scanner has several sensors to detect the status of the paper when it is in the scanner. You should clean these
sensors as part of your standard weekly maintenance of the scanner.
Note: Do not clean the sensors with the roller cleaning paper.
Preparation
• Turn off the scanner prior to cleaning the sensors.
• Locate the Blower Brush accessory that was provided with your scanner, this is what you will use to clean the
sensors.
• Remove the brush tip from the Blower Brush and set it aside, you will be using only the blower to clean the
sensors.
