Maintenance

This chapter describes how to clean and maintain the scanner.

Daily Cleaning

To ensure high-quality image scanning, regularly clean your CR-135i/

CR-190i 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 Feed Path

If dirt appears on scanned documents, clean the feed path. Clean the

feed path regularly.

Pull the Open Button, and pull the Front Maintenance

Cover open to the right and left.

IMPORTANT

If you notice paper dust in the feed path when you open the

Maintenance Cover, clean it out with a clean dry cloth or cotton

swabs.

Press the Open Button, and push the Back Maintenance

Cover open to the back.
