Maintenance
This chapter describes how to clean and maintain the scanner.
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.
