Hello,
I have a Brother MCF 8820 D fax printer, and all of a sudden, it prints very poorly or not at all. It is neither the cartridge nor the drum, and I keep getting the error "machine error 78". Does anyone know what is happening? Thank you.
Configuration: Windows XP Internet Explorer 7.0

    The instructions are as follows:

    1. Plug in and turn on the printer
    2. Keep it on but unplug it (do not turn off the switch)
    3. Press the "menu" button and plug it back in
    4. Wait and dial the code 91
    5. Wait and dial the code 99: it should display "maintenance" and return to normal if it works

    I hope this works for you. Thank you for keeping me updated.

    Have a good evening.

      Incredible !!

      In 2022, this manipulation still works for our Brother DCP 8085DN fax copier !!

      Thank you !

    And no!!! According to the repairman, it turns out it was the oven after all. Anyway, too many repairs, we had to buy another one, but we kept the device because I’m not sure about the diagnosis...

        I solved my problem and noted the manipulations to do for those who are interested.

        It is indeed either a malfunction of the oven or a blockage of the oven that can be unlocked.

        Have a good day.

        AS WE HAVE RECEIVED THE FAX, I am indeed interested in the procedures to follow. Thank you in advance.

        Sorry, we couldn't fix it, we've changed the fax. It seems it came from the oven which was broken...
