    C554 colour quality printng problems

    hi guys i have a c554 dumping magenta & cyan toner at the back of the developing units magenta is dumped more and carries on to the transferbelt.
    i have cleaned the dev unit on a previous visit and went back to the machine months later the problem came back, shows mostly on red coloured A3 copies see attached image lookat the line at the bottom of the image, i have test fitted a 2nd hand magenta dev unit which only lasted 2 weeks than it started again i have check the contacts at the back of each dev unit , done stabilization , adjusted density on the magenta & cyan , any suggestions i will change the HV unit on my next fisit also take a new drum and dev unit , front board also just in case just wondering if im missing anything......

      I'm on my phone, but I don't see an attached sample...

      I would have to look at the SM but I thought the two HV board control two IU each. I might be wrong, but if so, that would mean that both HV boards would be bad.

      If you have available, HV board(s) would be my next step.

          Check back of machine toner filter jammed?

          Blessed are they who can laugh at themselves, for they shall never cease to be amused.

              Haha the simple things... "it won't start" "does it have gas?"
              Probably check the fan operation too?

                  I still don't see that attachment ... do 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.
