    Ricoh MPC3003 white lines

    Hi,

    Weird problems on an MPC3003.
    Changed the developer unit lately because of white stripes, only in K mode.
    After the change no problems, black copy and prints were good. (no stripes)

    However, about 4K counts later, again white stripes. (see photo's)
    cleaned the laser, notice that again the developer rol is not completely filled with developer . .

    Anyone a solution or explanation why it returned after only 4K ?

    Thanks in advance

    Are you using genuine toner?

    I think the user use the cheapest paper and paper dust can contaminate the developer and the result can be like this.

    Is it the same toner bottle
    you could have an issue with lumps in the toner it may just be a bad toner
    when did the fault originally start was it round about the time they replace the toner ?
    if you are going to replace the developer unit again i would remove the toner vac out the toner pipes and replace the toner bottle as well

    I agree must be poor toner.

    If you clean the dv roller (run paper under the blade) & do a forced toner supply do the deletions move etc?

    The key is work out if there is a loss of developer or just contamination in the k dev unit.

    Re: Ricoh MPC3003 white lines

    Hi there!
    This was a common problem when the 1. METIS were delievered. 30% of our machines had white lines. But in the most cases it wasnīt the toner but little plastic-parts(!) from the production-process of the dev-unit. When the machine was in warranty we changed the box(es), out of warranty, we carefully opened the box and removed the garbage. Itīs also a good idea to clean the paperdustcollector when maintaning the device.
    Greetings...

    Do a dev change and fold over a piece of paper and run it between the mag roller and doctor blade. You have obstructions there causing the problem. Using OEM toner and developer helps, and make sure the machine filters are clean. Too much heat compounds the problem.

    NEVER ASSUME ANYTHING

    Changed the developer unit lately because of white stripes, only in K mode.
    when you say "changed the developer unit" do you mean a brand new unit which comes with new developer, or a used developer unit from another machine ? A new unit should not have this issue, a used unit from another machine, most probably will have. Did you take apart the drum unit and service it ? The wear of the lub bar on those generates a load of white powder that if not cleaned out can find its way into the dev.
