Perform the regular maintenance described below to maintain peak scanning
quality.
CAUTION
• When cleaning the scanner or the inside of the scanner, turn
OFF the power switch and unplug the power cord from the
outlet.
• Do not use spray cleaners to clean the scanner. Precision
mechanisms inside the scanner may get wet and result in
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 electric shock.
Cleaning the Scanner
Moisten a cloth with plain water, wring out the excess water, and then wipe the
exterior of the scanner to clean it.
Cleaning Inside the Scanner
Dust or paper particles inside the scanner can cause lines in scanned images.
Use a blower 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 any paper particles that are remaining.
