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.
• Never use paint thinner, alcohol, or other organic solvents to
clean the scanner. Such solvents can damage or discolor the
exterior of the scanner. They also 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 remaining moisture.
Cleaning the Inside of the Scanner
Dust or paper particles inside the scanner can cause lines in scanned images.
Use compressed air for regular cleaning of dust and paper particles from
inside the scanner. After finishing a large scanning job, you should turn OFF
the scanner and then clean off any paper particles that are remaining.
