Daily Cleaning
To ensure high-quality image scanning, regularly clean your DR-6080/9080C as
described below.
■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.
CAUTION

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.

Cleaning the Scanning Glasses and Rollers
A probable cause of stripes appearing on scanned images or dirt appearing on
scanned documents is dirt on the scanning glasses or rollers. Clean the scanning
glasses and rollers regularly.

power cord from the power outlet.
2 Close the document eject tray extension if it is open.

8 Replace the rollers that you removed. (See “Installing and
Removing the Rollers,” on p.91.)
9 Carefully close the upper scanner.
10 Press the upper scanner down firmly on both sides to close it.
If you press the upper scanner down only on one side, the opposite side
will not be fully closed. Make sure that you hear it click into place.
If paper jams or double-feed (feeding of two or more document pages) occurs
frequently in spite of your having cleaned the rollers, a probable cause is roller
friction. If this happens, replace the rollers. Contact your service representative.

Cleaning the Guide Plate (When Using the Imprinter)

detergent on a soft cloth that has been firmly wrung, and then thoroughly dry it
with a dry cloth.

Guide Plate
Cleaning the Ink Jet Nozzles (When Using the Imprinter)
Ink that collects around the ink jet nozzle may stain your documents or cause the
text to appear scratchy. Remove the ink jets and clean them periodically with
cotton swabs.
Contact
Do not touch the contact while you are cleaning the ink jet nozzles. Doing so may
cause incorrect printing.
Power Outlet
If you leave the power plug connected to the power outlet for a long period of
time, dust may accumulate at the power outlet, and cause a fire or electrical
shock. Clean it periodically.
