We have been having this problem for a while. It seems to happen once the printer is heated up with multiple page documents or multiple copy printouts. Starts with lighter magenta lines in the white areas and gets darker as more prints are done. Seems to go away once the printer cools down. All of the drums have been replaced and the problem still exists. Any ideas, adjustments, maintenance, etc that you can give me would be appreciated.

Re: C4080 magenta streaks on multiple pg prints
The drums are sealed with just a roller showing. The streaks on the actual print go the direction of paper feed (17" side of 11x17), were there before we changed the drums (months ago) and never went away after changing them out.Comment

Re: C4080 magenta streaks on multiple pg prints
I am not a tech, but have had experience maintaining and repairing different printers and digital presses through my printing career. I thought the problem could be beyond my knowledge of the machine, tools available and I was busy at the time so we had a tech out who cleaned and found nothing wrong with it other than the drums being low so we changed them out. Should I use (or not use) anything specific to clean the transfer belt?Comment

Re: C4080 magenta streaks on multiple pg prints
You just need to understand the 8 steps of xerography and you'll be in the clear, you already know mechanical. You're halfway there. Pre-exposure, primary charging, laser exposure, development, transfer, seperation, fixing, delivery. Once you "see it in your head" you'll have a small moment of zen.Comment
