Hi all,

I think i must do i firmware upgrade but i can't find any answer on web site.

I try to boot in maintenance mode, nogood
I install maintenance driver, ok
I download firwamre update tools but it seems to be work only on lan. Printer can't boot so i don't see it on my lan

Someone can help me and give me the good way, please.

Thank a lot

(sorry for bad english)

I progress.

Now i need a firmware for this printer. I can find update tool program but not working in maintenance mode.

I need a file like *****.pmu or other "pure" file.

It may be an IC chip on the original PCB was not swapped to the new board.????????

Thank for your response, but no. No IC chip, memory...

I think that new mainboard has got a blank firmware. Maybe a problem with this board.

[edit] I confirm, new board has no firmware... sad new. Without firmware file i can't repair this printer.
