4-1 Regular Maintenance

Clean the scanner on a regular basis as described below to maintain peak scanning quality.
CAUTION
■ When cleaning the scanner, turn OFF the power switch and disconnect the power
cord from the power outlet.
■ Do not use excessive force when removing or attaching the rollers. Doing so may
damage them.
■ Do not use spray type 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.

Cleaning the Scanner

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.

Cleaning the Feed Path

Dust or paper particles in the document feed opening or inside the scanner can cause lines in
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.
