Blurry lines at 5" interval, transversal to paper travel, also visible in color mode.
5" = PCU?

Re: mpc2800 5" lines

i would check the paper transport assembly,maybe broken pin in rear where it pivots.
OR the housing itself.
Sometimes i see ITB unit get humid from sitting and the cleaning unit does not clean right.
I would pull all drums,ITB unit and fuser and look for worn parts.
I just had one i took in trade and had sold and was jamming only on 11by 17 and it turned out to be that
rear plastic pin on the transport unit...I used a quality crazy glue and drilled thru it and used a this nail with a small
head to give it support..Now it works..

FShead, that is exact what i just did: paper transfer unit swaped, no good.
Checked ITB, F.U. pcu, seems to be all good.

I have no idea what the copy looks like..
I have done a lot on these series and was a real pleasure learning them..
I would stop a test print pre fuser and see if it on the unfused paper

Both pcdu & fu needs to be replaced.
Had a lot of bad luck in the previous weeks with referbishing Ricoh's.
Makes corona even harder to cope with.

Re: mpc2800 5" lines

Just checked and PCU's are about 5" in diameter. The Fuser belt would be more like 7".
So PCU would be what i would suspect.

EDIT: Didn't see your post that said you're going to replace those items.

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

Re: mpc2800 5" lines

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.
