Replacing the Roller Assembly
The ADF Roller may wear out and is designed to be a user-replaceable part. Problems with documents
feeding through the ADF is an indication that the roller may be wearing out. You should first clean the
ADF following the instructions in the previous section Cleaning the Automatic Document Feeder on
page 114. Excessive dust on the roller can make it appear worn and smooth to touch. You cannot
determine if it is time to replace a roller if the roller hasn’t been cleaned first. The roller should last for
approximately 200,000 pages scanned.
To replace the roller assembly:
1. Open the ADF cover. The roller assembly is located in the underside of the ADF cover.
2. Lift up the green lock flange to unlock the roller from the ADF cover.
