Replacing the Roller Assembly
The roller will wear out and is designed to be a user-replaceable part. A worn roller can cause
documents to feed in skewed at an angle, or multiple pages to feed at the same time. Before
replacing the roller you should clean it as excessive dust on the roller will make it appear worn and
smooth. You cannot properly diagnose a worn roller until you have cleaned it. You should generally
replace the roller every 160,000 to 200,000 scans.
Replacement parts can be purchased from the Parts & Accessories page for your scanner at
