    C224e/C284e/C364e/C454e/C545e cyan dev unit problems

    Please can i have any feed back regarding failures on cyan dev units as i have over 50 failures where the developer is depleted.
    This seems to be the only colour that fails.
    All the levels are as they should be.

    Thanks in advance for any info received.

    Check the operation of your toner add motor.

      everything is working correctly on every machine we go too.

      Levels are all ok.

      the toner replenish system on these models are not independent they all turn together which is unusual.

      One C364e that had the problem went through 4 dev cyan dev units in 4 days ( only producing 1500 copies ove this period )

      MFP,HV,Drum,Printer control board transfer belt all had been changed previously.

        You've had 50 cyan dev units fail!!?? Thats a lot, On how many differant machines is this?
        I trust you are using OEM toner?

          Still to this day have never changed a colour dev unit on any 4 series and we have LOTS.

          Only one i have changed is a failed black, and thats the only one. We only use genuine everything and replace parts when asked - we never reset and leave parts.

            We have many of these in the field and I have never heard of such. Don't think I have changed one either. I only had one issue when someone was able to get a cyan toner installed where the black goes.

              My reason for suggesting toner supply is we had a black dev. unit fail. (we thought). On this model there is carrier and toner in the toner bottle. It continuously replenishes the dev unit. It fills a toner hopper and then goes into the dev unit from the hopper. There are a couple of motors that run that process. We had one not working and causing the problem. Good luck.

                this is across 20-30 machines and yes we are using OEM toner.

                it is just not making sense as all levels are correct and it is only the cyan unit.

                  20 - 30 machines!!!??? You sure you are not using compat toner?? There's no way on GOD's earth you could be that unlucky to have that many failed dev units. If you are running out of dev and the machine is still supplying toner from the bottle id suggest that you have a word with your toner supplier as i really cannot see you having that many machines with the same problem.

                  i pray for you, Trigger

                      Something fishy is going on here.

                      Is there anything peculiar about the environments the machines are installed in that are in common ?

                        you havent said anything which if any error codes you may be getting when they fail, there is a FOC bushing for the 4 series machines for the dev units. May want to look for it on the KMtech website. But I agree with everyone else about the number of failures, if you havent taken this to KM tech support you are missing the boat.

                          The FOC mod has been fitted and trust me KM techs have been informed. PCQ occurs before anything else i.e codes or anything.
                          The dev unit completely drains out of all of the dev/toner and cannot be recovered.

                            All of the copiers are in office enviroments. Nothing out of the ordinary.

                              Going back to one of the first problem that occured on a C364e this paticular machine was all ok up untill about 60k within a period of 3 weeks it had gone through 4 cyan dev units in two weeks.
                              In between units PRCB,MFP,HV,transfer belt,PC drum,dev driver board and toner hopper assembley have all been changed.
                              I have KM attend and they were as baffled as myself.
                              We formatted HDD and took everything back to factory settings and loaded latest firmware at the time.
                              So far touch wood it has been ok.
