Replacing The Roller Assembly - Xerox DocuMate 3640 User Manual

Replacing the Roller Assembly

After extended use, the roller may wear out and will need to be replaced. It is a
user-replaceable part and can be ordered. See the section "Xerox DocuMate
3640 Scanner Parts List" on page 98 for the part number.
A worn roller can cause documents to feed in at an angle, multiple pages to feed
at the same time, or not grab pages at all as the roller slips on the page. If standard maintenance of
cleaning the scanner and replacing the ADF pad assembly does not resolve paper feed issues, it may be
time to replace the roller.
Please note that you cannot accurately determine if the roller has worn out if the roller has not been
cleaned first. Excessive dust on the roller can make it appear worn and will be smooth to the touch. You
can take the roller out of the scanner to clean and examine it before making the decision to replace the
roller.
To remove the roller assembly:
1. Lift the ADF cover release on the top of the scanner body to open the Automatic Document Feeder
cover.
Note that opening the ADF cover automatically disengages the toothed gear on the right side of
the roller so it can be removed.
