You probably have some build up on the glass, which happens if you use the auto feeder most often. Alcohol type cleaner will remove with a very softcloth. One small dot will look like a long streak on a feeder, much like a streaked fax. The other issue is the photoreceptor belt has nicks or is dirty eaither way it needs to be replaced. Try the cleaning first and you may have to look hard for the small dots built up on the glass.
