    Konica Minolta c6500 2421 developer issue

    So i am getting an alternating 2411 and 2421,
    it seems as though the developer is spilling onto the sensors and covering them which is causing the 2411.
    i then follow procedures to resolve the 2411 and after a little bit it starts throwing the 2421

    when i do io check on 54-00 it gives me a 3 and then a 2 and then a 1.

    the initial toner density sensor mode and etc all end up crashing to the 2411. and i have to remove the unit and clean the sensors..

    It seems like theres supposed to be a bit of a vaccuum on the top and perhaps that vaccuum is faulty?

    this one? ive cleaned it .

    when i look at the developer unit the developer on the roller part is thick and then its just all over the top over the sensors.. .

    is that thickness normal? is there a good way to check like.. cleaning pressure?

    yeah, thats supposed to draw misting toner, when it starts to clog, the whole process unit gets nasty.
    is the thin silver shutter closed on the front of the DV unit?

    here are pictures

    I previously moved the yellow developer unit into the magenta space and the issue followed the yellow developer,
    so we replaced the yellow developer unit , And now we get this.

    any advice is greatly appreciated.
