    Kyrocera Taskalfa 250ci Firmware - Error Code C7401

    I just installed the MK-865A maintenance kit for my Kyocera Taskalfa 250ci. After completing the upgrade, I got an error code C7401 when the machine booted. After some searching, it seems that the new developer unit requires firmware 11 or higher. Since I have the error, it appears I am older than that. Can you anyone put to me to the latest firmware (or at least 11)? I've been searching for a while and cannot find anything. The details of what I have are:


    Model: TASKalfa 250ci
    System Firmware: 2H7_2F00.006.043
    Engine Firmware: 2JZ_1000.010.004
    Panel Firmware: 2H7_7000.006.029

    Thanks in advance.

      Self diagnostic codes
      C7401 Developing unit K type mismatch problem
      Absence of the developing unit K is detected

      Causes : Developing unit connector inserted incorrectly.
      Reinsert the developing unit connector if necessary.

      Causes : Different type of the developing unit is installed.
      Install the correct developing unit.

                  You are at version 6.0 of the firmware from June of 2009.
                  Yes the most current firmware is version 16 from April of 2018. It appears that version 11 does have major changes to developing.
                  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.

                      Did you try sim 906?

                          I have not tried anything, firmware or sims, but only because I cannot locate them. Can anyone send me a file link with the instructions?

                              You may not have heard of it ... it's called the service manual.

                              LMGTFY

                                  Yes yes yes, I get the LMGTFY (personally I prefer RTFM - read the effin manual). I don't mind a good ribbing - but the firmware files are no where to be found. I'm just a lay person (not in the copier business), but I have spent hours searching the internet for the firmware. Kyocera's site only has manuals and drivers. I would love it you google'd it for me and sent me the link to the firmware files.

                                      You have to be a dealer to get firmware. Or hire a dealer that has it. =^..^=

                                          You have to be joking with that response - that was whole point of the thread! Telling me to read a service manual (which, btw, does not say anything about having to be a dealer)...life does not have to be this difficult. Just tell me "no" from the get go instead of having me jump through hoops.

                                          For those reading this, google "TASKalfa250_300_400_500ci_15.24.0010_(2013-12-20).zip" and you will find a few sites hosting the file. This will not get you to the latest, but it at least will get you recent enough to overcome C7401 error. I would post the file, but after the last reponse I suspect that is against "the rules".

                                          Lastly, if anyone happens to know the filename for the most recent firmware, please share so that we may fetch it on our own.

                                              You've got to upgrade to version 10 first:
                                              TASKalfa Upgrade Pack 10.00 10-06-10 without Options.exe
                                              TASKalfa Option Pack Ver 1.11 Firmware.exe

                                              Then you can upgrade to any of the following versions:
                                              Version 11
                                              TASKalfa Upgrade Pack 11.00 1-4-11 without Options.exe
                                              TASKalfa Option Pack Ver 1.12 Firmware.exe

                                              Version 12
                                              TASKalfa Upgrade Pack 12.00A 8-8-2011 without Options.exe
                                              TASKalfa Option Pack Ver 1.13 Firmware.exe

                                              Version 13
                                              250ci 300ci Combined Firmware Upgrade Pack 13 5-10-2012.exe

                                              Version 16
                                              250ci 300ci Combined Firmware Pack 16.00.zip

                                              The simple explanation is that on 10-06-2010 Kyocera split the Options off due to excessive file size. On 5-10-12 Kyocera split the firmware between Low: 250ci/300ci with options and High: 400ci/500ci with options. =^..^=

                                                  great info. Thank you (seriously)!

                                                  For what it's worth, I already performed the upgrade prior to your last post. I did not make me upgrade to v10 first - as far I know everything worked. I have the new developer in without any errors.

                                                          Hi, Would it be possible find this firmware somewhere, or can anyone share once more? I do have a problem with the scanner on my250ci, it makes a notice cannt use 2-side .. because of a fault. thx.
