    Hi folks
    Today i swap c1070s intermediate t. Belt cleaning unit with a new one.. but forgot to remove red screws from it.later realized it.. itb has no scratchs or whatsoanything im getting this white lines on print that wasnt before

    Itb belt seems okay no scratch
    I clean idc sensors
    Ran blade setting mode
    Ran color registrations
    Checked fuser
    Replaced itb cleaning unit

    Re: C1070

    Probably a dirty grid or two from piling up all that toner.
    Clean the primary charge units. =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.

    Re: C1070

    Thanks a lot for answering
    Yesterday i tried cleant all the charge grids
    Cleaned also dust proof glasses and even run the machine without them
    I blower brush around where the dust proof glass goes and the color reg sensors
    Checked drum and int transfer belt and no visible tear or mark
    Looked around trying to look dust or particles shouldnt be there and nothing
    Rewrite firmare clean all paper tray settings
    Factory reset some settings (as its a low vol machine 292k only)

    Problem still there
    This machine is driving me crazy

    I suppose you could have dirty laser optics. I'm assuming it only affects cyan. =^..^=

    Re: C1070

    I haven't seen it on this model, but I suppose there might be a hair or fiber dragging along the primary transfer belt, displacing the latent image. I've seen the same effect from a toner buildup on the upper fuser guide, also displacing the unfused image on the paper entering the fuser. Just guessing now. =^..^=

    Re: C1070

    if its on every ind. color it wont be drums or slit glass or laser with the same image. if its front to back also same answer. did you prime the cleaning unit with #2 yellow toner and turn the belt before you put it in? even though it has a blade mode it still has to be primed first. i doubt all drums coronas slit glass are doing the same thing. . put another belt in and prime it. or try the old belt. dont use the toner in the bottle. you need to order the yellow toner for priming. it has no dev in it. i have seen techs with this problem by not priming

    thanks bro, must look very well then, by the 2 times i have seen check this model with cellphone led lamp cant seem to find any
    the image enters like this to fuser so the problem is in earlier process but cant find it physically... will try to use setting powder on the itb to see if helps

    yeah the line goes edge to edge, i didnt prime it, it became like on the way to here got spill out on to roller, but didnt prime it
    i dont have any other belt, machine fairly new 295k prints only, never been replaced belt, under optimum conditions.
    you mean prime the belt or the cleaning unit? with oem item KM "SETTING TONER"?

    thank you

    The toner in the toner bottle has a percentage of developer, to replenish developer loss and extend the life of the developer. That developer included in the toner is abrasive and should not be used for priming. Konica Minolta sells yellow toner only for priming drums and transfer belts, in a small bottle. Does that make sense?

    Re: C1070

    this is the part # for the setting toner. A50UPP0100. use it on the blade and the belt. Setting powder may cause problems so use this toner
