    I replaced the new drums with old ones for a try but results are the same.

    I’m no expert but we had a C284e that had a Very similar looking issue. It was the HV board in our case.

    can you take a photo of level history and table number reading? Maybe this helps

    Now they changed from factory front housing of new K drums so it can't fit housing from old color drums.

    UPDATE

    Did before a mod from other drums and removed the plastic guide on the bottom center of drum in order to enter the drum place of C458, but like colleague said, the incorrect modding is the cause of poor drum colors.

    I replaced the entirely drum with C458 new right one and now it works.

    On the final 8 series of this machines is difficult to use old series drums if you don't really make a perfect modding of drums.

    Maybe the KM engineeries know this drum trick and try to resolve it! LOL

    Thank you, problem fixed (for now)

    :-)

    Cheers!

    Yeah we also had to learn it's not a good idea to screw around with that middle part - unfortunaly it might seem ok some tme after installing these falso modded drums until they opt out early
