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.
