Maintenance

This chapter describes how to clean and maintain the scanner.

Daily Cleaning

To ensure high-quality image scanning, regularly clean your CR-50/80

as described below.

CAUTION

• Before you clean the scanner, turn OFF the scanner and

computer, and disconnect the power cord from the power

outlet. Otherwise, it may cause an electrical shock.

• Never clean the scanner with any kind of organic solvent, such

as alcohol, benzene, or paint thinner. This may cause a fire and

electrical shock, or cause the exterior of the scanner to

disfigure or discolor.

• Never spray mild detergent or water directly on the scanning

glass. The spray could penetrate below the glass and

contaminate the internal light source and lenses.

Cleaning the Main Unit

Wipe the scanner with a firmly wrung cloth, moistened slightly with

water or mild detergent. Then, wipe off with a clean, dry cloth.

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.

Cleaning the Scanning Glass and Rollers

If stripes appear on scanned images or if dirt appears on scanned

documents, clean the scanning glass and rollers. Clean the scanning

glass and rollers regularly.
