By sponge roll do you mean PTR? As it is affecting all colours the same it could be ITB, PTR or fuser.

looks to me like transfer issues towards the middle of the page. Probable tbelt assy, or even dv unit for magenta

You will need to replace pcu and dev assy most probably

If it were one color only then you would need to replace the PCU/Developer. Since it is exactly the same pattern for all 4 colors, it is must be something common to ALL colors like a dirty PTR.

I can only see one back ground colour with is magenta also the ptr roller would be colour because the magenta is placing to mush toner on the belt with is going on to the ptr very common problem but sorry if I was mistaken.

Looks the same to my eye.
However Ricoh are different animals from what I've seen before and work on today so I could be wrong.

I was looking at the light streaks running the entire length through all the colors.

Those white voids/spots and streaks in my experience could be very well from compatible consumables(toners, etc). OP never mentioned what consumables are used. I always hated to fight ghosts when customers use non OEM parts.

The yield of PCDU as far as i remember is at 80K. It is worth replacing if you have reached above the PM counter.

60K
120K for everything else

Re: Ricoh 2550 Print Not Clear

What i find strange is that the 2 machines have the same problem.
Are they in the same room with same customer?
What are the counters?
Which counter PCU's, ITB, PTR?
Is machine standing in normal office conditions?

Re: Ricoh 2550 Print Not Clear

The pcu is 60k
The dev unit is 240k
