Konica Minolta C454 after change MFP board error C-D291

[gateway.vly@gmail.com]

Dears we change the C454 MFP due to the old MFP network port not working the network status led always on even the network cable disconnected . we purchased new MFP board that board always shows error C-D291 , we try to update the firmware then we get error message (invalid external memory).
the firmware usp work very well with old MFP board.
any suggestion please.

Ohhhhh no.

I had to do this once, and only once for a device that got hit by a lighting strike!!! Exactly the same issue, ethernet port dead, copier fucntional.

If you have not followed the procedure detailed in the Service manual as well as the additional Technical Bulletin you may have turned your machine into a paperweight.

There were detailed instructions on how to do this, including a special pre-boot firmware that had to be used in conjunction with the MFP Reset Tool.
This invloved booting the machine back to KM factory, which causes the display language to revert back to Japanese and other wonderful steps to follow.

If you have just physically baord swapped the machine and turned it on I am so sorry for you and the pain you are going to have to go through to ressurect your device.

Good luck.

Thanks for donating. Maybe someone else get help or contact admin on why it's not showing under your name. It would benefit you to have "site contributer".

"CAUSE: New style CCD (p/n A2X0R72111) was installed without updating firmware to G20-K9. Also make sure there is a good connection to the CCD.

"SOLUTION: Update firmware to G20-K9 and check the CCD cable (p/n A2X0N14500) connection to the CCD

thanks for your reply, the ssd board worked with ols mfp board with old firmware FW_A1610Y0-F000-GR7-M0. old mfc board network port issues.we tried the reset tool copyman send to us . but once the ssd recover done the D291 again shows . can you help me to get G20-K9 firmware

K9 firmware is so old that it is no longer available through the KM USA website. Anything newer should also contain the necessary files needed to work with the newer CCD. If you still have a copy of the GR7-M0 firmware, that is the newest available.

Was the MFP board you installed new? If not, you will need to make sure that the machine type set in the board matches the model of the machine you installed it into. Unfortunately, you need the ability to boot into the firmware update screen in order to do this.

If it was a used pull, and came from a different model of machine, give this a try. Just note that I have NEVER TRIED THIS, so it may not even work. Try booting the firmware for the model of machine that board came out of, instead of the machine it is in now. If it does boot to the firmware update screen, DO NOT LET THE UPDATE RUN! Use that to change the machine type, then boot again with the correct firmware and hopefully it will go this time around.
