mpc2800 5" lines

[mga]

Blurry lines at 5" interval, transversal to paper travel, also visible in color mode.
5" = PCU?
Thank you again for your answer.

Really need to see samples

Run individual colors one at a time to see if it's one of the drums.

i agree with you.
make sure individual colors is turned on and do partial 2 inch sky shots with paper blocking lead and trail edge.

i cant see 4 drums all going bad at once

Hoi,Thank you for your helping.
I'm going to swap units to see what exactly is causing the problem.
It's a multitude problem, caused by more than one part and performed after approx. 30 prints...
Ghost image, smear image, dots...
I' ll keep you informed.

We bought this machine via a auction company.
I think there was some cheating on this machine, because i never have seen such a dirty and worn out cl unit!
Also - and Probabely - they have tried to clean the pcu, because there was a "zone" - every 5" - on the printouts where the image was smeared.
We never test those machines before bying it, because the test-day is at a different time, and since this company is miles away from where we life, we see it as a "gamble". Mostely we are lucky .

here in ny the auctions are mostly shady..
I only buy lease returns and once in a blue moon will get a bad machine.
I had one that must have had chemical around it as the metals were pitted and grainy.
I just gut it and save what is good..
It is time vs real cost..
And i can always get another..
where are you located?
