SSEMBLY
After extended use, the roller may wear out and may need to be replaced. It
is a user-replaceable part and can be reordered.
Frequent paper jams are a symptom of a worn roller assembly. A worn roller
can cause documents to feed in skewed at an angle, or multiple pages to
feed at the same time. A worn roller should be replaced to avoid damage to
the scanner’s internal parts. 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.
1. Press the ADF cover release on the top left of the scanner body to open
the Automatic Document Feeder cover.
2. Remove the scanner’s paper input tray as the roller is seated in the body
of the scanner behind the tray.
3. The roller is held in place with a lock tab that rotates to lock and
unlock it. To unlock the tab, rotate it upward until the small lock
flange is completely free.
4. When the roller is unlocked, it can be removed from its mounting
sockets. Gently press the roller to the right to free its left side. Then
angle the roller to the front of the scanner until it is clear of the
housing, and bring it out and away from the scanner body.
