I have xerox workcentre 7655. when i copy or pint in colour there appears blue dots every 1.2 inches and below that on a band random blue sponts. Please help
Since this happens when you copy and print, you should call service. Provide them your serial number and they will place a service call for your WC7665.
It sounds like a drum but it could be the cyan developer housing if the spots are random. The developer housing it what the drum sits next to.
thanks for your suggestion, I did exactly as you suggested. Now there are no cyan spots nor do i see yellow spots. some pages i printed had a very fine blank verticle line in the same zone ( only in some pages). so i will print again tomorrow and day after and post if i see something strange. My many thanks to you for showing interest on my post. I shall again post on thursday. thanks again
