A coworker has a Bell Howell 500FB scanner. She scans tons of documents with it on a regular basis. Apparently, this scanner has been used for a number of years. She has no problems with misfeeds or anything, but the scanner now makes a lot of squeaking/squealing noises as it scans -- much like a car with a squeaky serpentine belt.
Are there belts inside that may need cleaning, replacing, or tightening? Or is there some other solution for a squeaky scanner, such as cleaning or oiling some gears or something? Basically, my question is: what is this problem and how can we fix it?
