Daily Cleaning
To ensure high-quality image scanning, regularly clean your DR-5020/5080C as
described below.
• Before you clean the scanner, turn the scanner and computer power OFF and
disconnect the power cord from the power outlet. Failure to do so might cause
electrical shock.
• Never clean the scanner with any kind of organic solvent such as alcohol, benzene
and paint thinner. Doing so might cause fire and electrical shock, or cause the
exterior to disfigure or discolor.
• Never spray mild detergent or water directly on the scanning glasses. 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.
