    BHC252 C2555-p8/p21 codes

    Reset yellow IU and code cleared. Then noticed P-8 and p-21 codes. Reset all toners and Iu's, but didn't clear. Some poor copy quality, mostly in yellow. Should the yellow IU solve all this? What about p-21 code?
    Thanks.

    Hi there!
    If there are p-8/-21 warningcodes there is normaly a colourregistration-problem. All our bizhubs with this kind of warning needed a new image-transferbelt-assy, then the problem was solved.

        Thanks. I inherited several of these machines, I'm not a big fan of KMBS color! I forget about those sensors, but I do know where they are. Is it always a good idea to blow out those sensors when p-codes appear?
        thanks.

          The KonMin C250/252 is a dog for sure however, I have worked on most other KonMin business colour machines and I can tell you they are one of the best if not the best business colour line of copiers.
          To answers your question, it is never a bad idea to clean the IDC sensors.

            Only if P-21 shown on screen without other malfunctions,
            when u have other P shown, its logical that transfer will not read all walue correctly

              Something like this came up in C360 class. During a previous class session the solenoid operated sensor cover was not installed correctly. There is a white plastic lever that must fit into a cutout in the cover (at least on the C360). Maybe this can help you. =^..^=
              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.
