Cleaning the Scanner
Keeping the scanner and scanner glass clean ensures the highest quality copies, scans, and sent faxes. Dell recommends cleaning the scanner at the start of
each day and during the day, as needed.
1. Dampen a soft lint-free cloth or paper towel with water.
2. Open the document cover.
3. Wipe the surface of the scanner glass, underside of the white document cover, and white sheet until they are clean and dry.
CAUTION: Do not touch the transfer roller inside the printer. Oil from your fingers may cause print quality problems.
NOTE: If there are lines present on copied or faxed documents, check your scanner and scanner glass for any particles.
