How to flash Fuji DX100 firmware onto an Epson D700 mainboard?

[majo73]

Good day.

I have two Fuji DX100 printers and one Epson D700. One DX100 has corrupted firmware (the printer shows error D1F2) and the other no longer communicates with the computer. Until recently both were working, but within three days they stopped functioning. I want to use the working mainboard from the Epson D700.

Using the service software, I attempted to flash the Fuji firmware. I tried versions CP416I3.UPG and CP417J5.UPG. In the service program, the Printer Status still shows the original Epson firmware CB424I8.

Could someone please advise me how to get the Fuji firmware into the mainboard?

Thank you in advance for any help.
