When printing black dots appear chaotic, over the entire sheet of paper. What to do?
If the black dots appear on every sheet of paper it could be the fuser unit is wearing out or the drum unit. The way to check that is to stop a print half way through and remove the paper. If they are not there before the fuser unit but after it then it will be the fuser. Or if they are there before the fuser unit it will be the drum unit. If it they only appear specfic to one source then it is likely to be the source of the document. IE copying - check the optical area (scan glass etc). If on incoming Faxes it may well be the sender that has the problem and is just transmitting them to you. Hope this helps.
