Cleaning procedures
The following cleaning guidelines and procedures will help ensure best
scanner performance.
NOTE: Use only the recommended cleaning supplies when cleaning
the scanner.
• If paper jamming, marking or multiple-sheet feeding occurs
frequently, clean the rollers, sensors and imaging guides as
described in this section. If paper jamming, marking or double
feeding occurs frequently even after cleaning, you may need to
change the rollers.
• To maintain scanning quality, clean the scanner at least once a week
or after 20,000 sheets have been scanned, whichever comes first. To
determine the number of sheets scanned, use the User Utility. See
Chapter 5, User Utility
for more information.
• Be sure the documents you scan are clean. If the documents you
scan are dirty, the scanner components will also become dirty.
• It is recommended that you clean all of the rollers at the same time.
