Re: C7000 thin multiple lines (only black) on one side of the paper

if your consumables are good and the cq adjustments were preformed when new supplies were installed, I would look at the anti misting vacuum system. the entire pathway including the fans gets clogged with toner.

Hi Albonline, thank you for your response!

What is CQ short from? I'm not a real tech, so don't know all the terms and trying to translate it correct to my language.. Just trying to learn the best I can Do you have a picture or anything what path I need to look at?
The streaks are on only one side and really straight. Could it also be a bad black developing unit? Also had code 2814

The best advice i can give you is to get a service manual for the model you are trying to fix .look at the theory sections for explanations on how things work. and where stuff is.

Hi,
I thought I had placed a response on this problem, but didn't, sorry about that!
I'm only 33, but forget literally everything. And have some trouble with finding anything on this new website...

I don't have the black lines anymore. What I did.... is that I created some ' distance' between the drum and the developing unit.
So when you position the developing unit in it's place, his 2 black 'foots' (don't know what to call it in English) are shoved into their place against/into 2 plastic 'holders'. I added a photo so you know what I mean (bit difficult to explain😅) So I've place a thin plastic clear sheet between the foot and the holder on the right side. Seems to be working so fine by me!

I came with the idea because someone on this forum contacted me and give me another manual with way less pages (not the big service one) and read about this problem.
I've added a picture of this page. Didn't feel safe to put on tape on the drum, so instead I used that plastic bit. This can't go anywhere and is stuck there.
Maybe it can help someone else!
