Daily Cleaning
To ensure high-quality image scanning, regularly clean your DR-6080/9080C 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 might cause an electrical shock.
■ Never clean the scanner with any kind of organic solvent, such as alcohol, benzene,
or paint thinner. It might cause a fire and electrical shock, or cause the exterior of the
scanner to disfigure of 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.

7.1 Daily Cleaning
Cleaning the Document Detection Sensor
Dust and debris that collects on the sensor will cause false recognition. Clean the
sensor periodically so that dust and debris do not collect on it.

Replacing the Rollers
The feed rollers (pickup rollers, feed rollers, and retard rollers) are consumables.
The feed rollers need to be changed periodically to maintain scanning quality.
When to Replace the Rollers
If the total number of scanned documents exceeds 250,000, a message for roller
replacement appears when you restart the computer. In this case, buy the
exchange roller kit and replace the feed rollers (pickup rollers, feed rollers, and
retard rollers).
Be sure to reset the counter after changing the counter.
Important
● Windows NT do not support a function to display a message for roller replacement.
To confirm the total scan, check “Total Scanning Count” in the “About” dialog box of
the ISIS/TWAIN driver and replace the feed rollers if the count shows around 250,000
scans.
● Contact your sales representative for information about exchange roller kit (pickup
rollers, feed rollers, and retard rollers).
