Cleaning the Scanner
Keeping the scanner and ADF glass clean ensure 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.

2. Open the document cover.
3. Wipe the surface of the document glass and ADF glass until it is clean and dry.
4. Wipe the underside of the white document cover and white sheet until it is clean and dry.
5. Close the document cover.
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 ADF glass for any particles.
