Regular Maintenance
Clean the scanner on a regular basis as described below to maintain peak
scanning quality.
CAUTION
• When cleaning the scanner or inside of the scanner, turn OFF
the Power Switch and unplug the power cord from the outlet.
• The power needs to be ON when cleaning the rollers and the
shading boards. Be careful of electric shocks when working on
the scanner while the power is ON.
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.
CAUTION
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 and
electrical shock.
Cleaning inside the Scanner
Dust in the scanner may cause the sensors to malfunction or leave marks on
the images. Periodically use a blower to clean dust from inside the scanner.
