You should clean the inside of the scanner at least once a week or as needed depending on how often the
scanner is used. If cleaning the scanner does not resolve any image quality issues, please follow the instructions in
the next section for calibrating the scanner.
You will need the cleaning cloth provided with your scanner.
Caution: use care when cleaning the scanner to avoid damaging the sensors. The paper sensor and
scanner cover sensor are plastic levers inside the scanner. They are fragile and can break.
The paper sensor lever runs along the front of the scanner. If the paper sensor becomes damaged, the scanner
will no longer detect when paper has been inserted into the scanner. The cover sensor is located on the left end of
the feed roller. If the cover sensor becomes damaged, the scanner will no longer detect when the cover is closed.
1.
Place your thumbs on either side of the paper feed slot, underneath the lid of the scanner. Hold the scanner
sides firmly and pull the scanner lid up to release it from the body of the scanner.
Use both hands to open the scanner, the lid is held down with locking arms on both sides of the paper feed
slot. If you open only one side, you may damage the scanner lid.
