Maintenance
Routine Cleaning
Clean the scanner on a regular basis to maintain scanning
performance.
WARNING
• For safety, always turn the power switch OFF and disconnect the
power cord before cleaning the scanner and the inside of the
feeder.
• Do not use spray-type cleaners to clean the scanner. Precision
mechanisms may get wet and malfunction.
• Never use paint thinner, alcohol, or other solvents to clean the
scanner. Doing so may deform, discolor, or dissolve surfaces, or
result in a fire or electric shock.
Cleaning the Scanner
Use a cloth dampened with water and thoroughly wrung out to clean
the outside of the scanner, and use a clean dry cloth to wipe the
scanner dry.
Cleaning the Feed Path
Dust or paper particles in the document feed inlet or inside the feeder
can cause spots to appear in scanned images. Use compressed air to
periodically clean dust and paper particles from the inlet and inside the
feeder. In particular, be sure to turn the scanner OFF, and remove the
dust and paper particles after scanning a large volume of documents.
Cleaning the Scanning Glass and
Pressure Board
If streaks appear in scanned images, or if scanned documents
become dirty, the scanning glass and pressure board may be dirty. Be
sure to clean them regularly.

Open the feeder gently, and use a clean, dry cloth to wipe
the scanning glass and pressure board clean.
