1. Regular Maintenance
Clean the scanner on a regular basis, as described below, to maintain peak
scanning quality.
CAUTION
• When cleaning the scanner and the inside of the scanner, turn OFF the power
switch and disconnect the power cord from the power outlet.
• Do not use spray cleaners to clean the scanner. Precision mechanisms, such
as the light source, may get wet, and cause a malfunction.
• Never use paint thinner, alcohol, or other organic solvents to clean the
scanner. Such solvents can damage or discolor the exterior of the scanner,
or create a risk of fire or electrical shock.
To clean the exterior of the scanner, dampen a cloth with water or a mild detergent,
wring the cloth out thoroughly, and then wipe the dirt away. Then use a dry, soft
cloth to wipe away any moisture.
Dust or paper particles inside the scanner may cause lines or smudges to appear
on scanned images. Use compressed air to periodically clean dust and paper
particles from the document feed opening and the inside of the scanner. After
finishing a large scanning job, turn OFF the scanner and then clean out any paper
particles remaining inside the scanner.
