Cleaning the Sensors
For best scanner performance, clean the sensors at least once per
week using a clean, dry, lint-free cloth or a camel hair brush. Use of any
other cleaning materials could damage your scanner.
NOTE: Clean the sensors daily if you are scanning carbonless paper
or if you are using the document printer (Scanner 3520DP
or Color Scanner 4500DP only).
1. Follow all of the steps in “Lowering the Pod” in this chapter.
2. Remove the feed module by pushing it to the right and lifting it out.
3. Wipe the sensors with a clean, dry, lint-free cloth or camel
hair brush.
4. Wipe the sensor reflective strips directly opposite each sensor.
5. Replace the feed module by aligning the pins and fitting it
into position.
6. Close the pod firmly.
