Excessive dust on the rest of feed rollers in the scanner will make a squeaking sound as it feeds the paper through.

How often should I replace the ADF pad? A worn ADF pad does not push the paper fully against the main pick-up roller causing multiple pages to be fed at one time. The ADF pad can last up to 20,000 scans, however it should be replaced as needed if regular cleaning does not resolve miss-feed issues.
