RICOH MPC3003 whitish stuff on color pattern and printouts

[Pixtech Frameworks]

Hi All,
I trust everyone's fine. A customer called my attention today concerning this white stuffs that appears on printouts, and I did color pattern and found out something was wrong somewhere, I've swapped transfer belt film and do some thorough cleaning still the same, this is my first time to encounter this problem. Does anyone what could be the problem? Attached is a sample of the color pattern.

You have a repeating pattern. If the bottom of the paper is the leading edge, I would say the fusing unit.

Absolutely. OP do some maths and measure the distance you will find what's roller diameter.

Funny enough, when u print black it doesn't up on it, except color

Not fuser unit slimslob. Another unit was inserted on the machine, it was still the same.

How do the colour PCU's look? Genuine toner?

My first thought: I'd also say fuser unit .........................but on the other hand the missing toner should be visible as "offset"


That "Genuine toner?" question is a good one - I'd also try and interrupt the print process wile printing full bleed test samples and check the components.

Edit: Perhaps it's an issue with the transfer roller/transfer on paper process - in this case a lot of residue of the image would remain on the upper side of the ITB

I think it is caused by the paper transfer roller, look at the distance between the repetition of the fault and the diameter of the diferent rollers in the MFP.

Excessive moisture in the paper could also lead to similar defects in the transfer.


Have you tried using new paper? I usually carry a pack of folios inside a bag with closure and several desiccant bags, which are sometimes in shoeboxes or when new machines are installed.

in base at the distance, seem a humidity condensation or grease/oil stains on one of the four opc drum surface.

From what you see in the test pattern, at least the problem appears in cyan and magenta, so it seems more of a transfer or fuser problem.

Not when type and thickness are wrong.

Try changing the paper thickness ,as thick 1 or Thick 2 and see if that makes any difference,If it gets better than you have issue with Paper itself or Toner being the issue.

Paper transfer had been swapped, still the same.
