    Angry Konica 1250 toner piles on charging unit sides after 5000 copies

    I have replaced the developing unit, a new charge unit, new cleaning unit assembly and a new drum, the problem still happens, I have also lowered the density to - 3, any ideas what should I do next? IMG-20210319-WA0000.jpgIMG-20210319-WA0001.jpgIMG-20210319-WA0002.jpgIMG-20210325-WA0025.jpg

    Have a look at the upper cleaning unit seal. It will wear to a tapered edge then fold over, and act like an additional charging device. =^..^=
    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.
    5) You are the person onsite. Only you can make observations.

    Thanks for your reply, what you're saying makes sense, however the entire cleaner unit was replaced brand new for this issue.

    perhaps the transfer belt is not transfering all the toner also replace transfer belt rollers. 951 does same thing.

    If its done its yield or close to it. Not much to go wrong on the transfer belt assy.
    The toner dusting in that area would suggest a problem on the cleaning unit the cause of it is unknown but check that there is nothing deforming the cleaning blade.
    Whatever
