    Re: Error Code C-6756 in ineo +454e

    With most machines now, but especially Konica Minolta products, it doesn't work to swap around boards. Replacement boards (like those from the manufacturer or Hytec) are initialized, and ready to accept data from the other boards within your machine. When you follow the procedure in the manual to install a replacement board it retrieves data from other sources (SSD, MFPB, and print controller) to "marry" the replacement board to the machine. Once "married" it will not work in any other machine, unless initialized and replacement procedure is followed again.

    Swapping minor boards like a paper size PWB will still work, but major boards will not. In many cases I've seen machines made unfixable by swapping multiple boards. You can discard this technique of troubleshooting on machines manufactured any time after, say year 2000.

    =^..^=
    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.

      My luck...

      Got the same problem.
      The trouble code history will show C-F907. The code appearing on the screen is secondary.
      C-F907 is an abort code relating to SIO Relieving port...DF
      In short the MFPB is #$%^.

      But why what toasted it?? The DF or dual scan ??
      Whatever

          What machine and type have you set when you were replacing the MFPB? and what have you got now during FW loading procedure?
          the firmware i flashed : A5C10Y0-F000-G20-J9
          during the FW update it went normale selecting the firmware and install

          that's what i was going to do change the MFPB !

          then i found in my archive MFPB Reset Tool i rest it and it worked fine and the error gone

          now the printer is working fine BUT from Code C-6756 and the printer just displays the error and the motors doesn't start > to error C- E301 > to working fine i couldn't think of any source of the problem other than detaching the wires and put them back helped to start the motors maybe !

            Just to clarify. Do you have a printout or know the version of firmware prior to loading the G20-J9?
            There were some issues with J-series of firmware btw.
            Also, if there was previously G00-xx firmware and you have jumped over the version up firmware (G20-A9) there might be your problem.

            Byting on bits.
            .OK Google! ... will I need Berrocca this morning?

              So you are saying only a board reset will fix the problem if i keep the firmware where its at?

                I'm sure that's not accurate allan. Part of the MFP board reset procedure is to reload the firmware. It can't be skipped.=^..^=

                  Ok .
                  Never done it before not a big board changer.
                  Makes sense a i would be wiping it.
                  I will then use 00-A9 to start with.

                  The board has been ordered so i am going to give the reset tool a try anyway.

                          Sorry for my blond moment. What do mean by B-range?! GB4-A9 you mean?

                            What i meant was B/W's.

                            A61FFW
                            A55VFW

                            My bad they are both for B/W.

                              allan, do you need firmware?
                              We know a thing or two because we've seen a thing or two.
                              The medication helps though...
