    [Error Code] Konica Minolta C7000 error code C2814 help

    Hello! I just replaced all drums, with new blades and coronas.

    When I try to do the Gamma Automatic Adjustment (selected 0) the printer will give me the code C-2814. I know it's black and the manual says it could be the Printer control board, black developing unit, IDC sensor or the IDC shutter solenoid. But how do I know which one is the troublemaker?

    The IDC sensor and IDC shutter solenoid are the ones who are looking at the belt? Schermafbeelding 2024-02-26 om 15.41.09.jpg this one?

    I just wiped them with a cotton top and a bit dirt came of, but it's still giving me the code.
    How do I know if there's something wrong with the lack developing unit or sensor?

    If I called a tech they will be here over a week or longer, because I don't have a contract.
    The work can't wait. Is there another way I can 'prevent' it giving this code? I can log in with the service code, so adjusting anything won't be a problem. Because now when I try to print it's also giving me instantly the code 2814.

    Hopefully someone is able to help me

      That looks like the IDC shutter assembly but what is the developer life at? If you aren't a trained technician you could do more harm by just replacing things. Why did you replace drums?

          did you clear the drum counters first?
          just asking.
          We know a thing or two because we've seen a thing or two.
          The medication helps though...

              Hi Synthohol, I cleared the counters of the drums after replacing them

                  Hi Markks, thanks for responding!


                  Could the IDC shutter assembly create this problem?

                  Developers were replaced last year, but the counter of the developing unit is 105 (limit it says 100). So didn't replace them, there are quite expensive..
                  I had several bad drums, so figured to just replace all of them..
                  Also replaced the fuser belt, forget about that one. Everything I replaced I put the counter on 0, after replacing.

                  If I need to replace parts, it will take mostly 2 weeks (if I can find them, most come from China, because there aren't really sellers in my country)

                  If I could I would call a tech and do it right or buy a new printer (because well it's old, but a great one if it works) But I'm not able to that so, hopefully later this year when things are better. I would be less frustrated and being able to do my job properly

                  I'm already glad I can find and ask for information/advise on this forum fro people who have experience and know what they are doing.

                      An idea. What if the problem is the developing unit black. There's too much toner in de unit, because the waste toner isn't being removed quickly enough?

                      I saw that the foam sealing from these waste toner disposal of each color (don't know how to call these in English) are mostly gone or flattened.
                      I have new foam sealing but I don't know how to disconnect those plugs (I believe there are 3 of them) to replace the old sealings with new ones.
                      It's difficult to reach them via the transfer and drum units.
