    Dare I ask - did you try another toner. We have had some faulty ones in the past. One instance it took three before one worked.

      Anyway, I replaced the control board, swapped the EPROM chip, and now the machine won't get past the initial screen with the five columns you get when you first turn it on. I have ordered two boards, I get the same with both. I tried putting in the old board, and it boots past that screen and throws the magenta toner error.

      Any ideas on what to do to get this pig back up and running? Many thanks in advance!

      First thing to try is a new toner, I have seen that type of error a few times and a new toner fixed it, also this is a setting in service mode to force the machine to add toner, I called tech support one time and we were able to figure out the problem that way.

        Hey guys,
        First of all-thank you to the techs who tried to help with this issue, it took me 4 days to figure it out, but I did get this machine up and running like new...
        I tried multiple toners to answer the above question, and indeed reloaded FW as well, but the FW I couldn't do until I got past my original issue. Konica support was absolutely no help, and so this took some digging and some shooting in the dark.
        So the two things I did that seemed to get the board working...1. I reinstalled the old board, in order to get the menus up, and by using the stop 2,2,2,0,0, super secret service mode, lol, I was able to turn on engine DW softswitch 59 to state 1.
        2. I installed a new toner holder.
        3. I reinstalled the board, (new oem) and boom, problem solved.
        Thank you guys who tried to help, though this wasn't a great experience for my first time on this forum, I can see it being a great resource to have in my future. Thank you!

          Congratulations on your success! How did you pry that little tidbit out of the hands of the hotline? They're pretty tight lipped about those super secret service modes. Usually they would let me struggle for a month, then send the rep down to do it while I wasn't looking. =^..^=
          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.

            to be honest, updating the firmware you are just opening up a new can of worms really. if its working then why update it, obvious there was a system dip switch that had to be turned off/on, but good job in repairing.
            sometime you have to not follow the manual, sometimes those thing just makes you spend money. just take your times and relax.

              So once you turned on the switch to see the engine DW what did you do from there? That was the area I was refering to I just couldn't remember at the time. I think it was switch #5 I turned on.
