what do you guys think could be causing this black dotted line on the very top of each page printed by a Ricoh 4055ASP (see attachment, can't show whole A4 due to privacy)
I'd replace the PCU/D but this has been done just about 25k ago together with the fusing unit and transfer unit
Problem just started today. Could it be faulty PCU/D again?
Machine is at 525.000 pages.
Perhaps there's a little dustball between the drum and cleaning blade. Guess it should be fine after cleaning he drum/charge roller/blade + waste toner auger area.
If this line is only visible after printing stuff with some coverage it could also be the fuser sleeve - the defect should be easily visible on the sleeve if you take a look.
Looks a bit like overtoning, are you running original toner in this machine?
Yes, always used original parts and toner.

Ok, thanks for the info, I will disassemble the PCU/D and have a look. And before that I check the sleeve on the fuser and try to print with coverage/non coverage - good idea.

well... if your problem its the privacy...you could also attach a counter page! so i have to guess.
I'm betting on the film on the sleeve, which has lost its non-stick coating at one point (as long as the page is facing how I image it)

The problem is that the machine is quite far away - and sadly I only have been sent examples that contain internal info that I obviously cannot share.
I'm often there but I wanted to get some opinions from the experts and cool people here first
The page is coming out vertically (portrait) and the line goes horizontally, so it could be a roller / sleeve. Which would be wierd because it has been renewed just 25k pages ago.
I'll have a look. Thank you all. Much appreciated. I'll update this thread when I figure out more.
From what I can see on you thumbnail it appears to be the cleaning blade or paper lint build up in the or around the waste toner coil creating a lint bunny that is making contact with the drum surface, I have seen that a lot with paper that has a high lint content.

I didn't read correctly that the fuser was changed, it's almost certainly what slimslob says
Just to update this thread, we ended up ordering a whole new PCU/D and did get a ~80% something refund for the defect part from ricoh (as it run for a short period).
Nobody would have paid spending hours looking for the cause and opening up the new PCU/D hence we opened an RMA case.

Bravo, that's how it's done, you ask for help, but then for fairness you come back here to explain how it was solved....if only everyone did this!
