Firmware Is Great | Copier & Multifunction Firmwares

Buy them - or else get a technician to do it for you.

If you buy them, you're on your own. As the site disclaimer clearly states, they only sell you the firmware, they won't be liable if you break anything.

If you get a tech, you'll get someone with the proper expertise to do it.

If you decide to buy and update it yourself, let us know - I love a good car crash (when I'm not on it)
