    P 8 is yellow image unit failure. Either you have a bad IU or there toner density level if off.

    From da book:

    P-8: Yellow Imaging Unit failure:

    Relevant Electrical Parts
    Imaging Unit C
    Imaging Unit M
    Imaging Unit Y
    Imaging Unit Bk
    Image Transfer Belt Unit
    Step Action
    1 Select “Image Adjust” → “PRT Max Density” and, if the setting value is negative, readjust.
    2 Check the drive transmission portion of the Imaging Unit and correct as necessary.
    3 Clean the AIDC Sensor window if dirty
    4 Clean the contact of the Imaging Unit connector if dirty
    5 Change Imaging Unit.
    6 Change the Image Transfer Belt Unit.

    Regards!

    Got it! I ordered a new yellow imaging unit, hopefully that should do the trick!

    Re: Error code P-8

    Hello everyone . I have a very annoying problem, namely a Bizhub C454 equipment displays the P8 error after each stabilization. I mention that the transfer belt is new, used only original toners, brand new cmyk unit drive!!! The only part that is not changed is the yellow development unit, which I suspect is also the problem. Today I got hold of a yellow development unit and changed it but the result is the same. Do you have any idea what else I could do?

    make sure the IDC sensors are clean
    We know a thing or two because we've seen a thing or two.
    Also don't ask me for files without a contributor badge.

    What do you mean by cmyk unit drive and why you changed that?

    I changed all the cmyk cylinder units to see if the error still persists... the P8 error is there

    4 complete drum units - originals are quite expensive even if you used 4 black units and 3 chips. Aftermarket drum units or only cylinders or new OEMs? You left so many things unclear so trying to help is like pulling teeth.
