I can't get this NIC to re flash correctly. I have v7.12 as a bin file and it is the only version I can find. If you telnet to the printer and tell it to download firmware then run the command "tftp -i 192.168.10.18 put oki6120_0712.bin OkiLAN" the printer will start the download then respond with Error on server : Error, incorrect binary file sent. I have been playing with this for weeks now and have a number of cards with issues that Oki claims will be fixed by this upgrade.
