Default Username and Password for Okidata C3400

I had some difficulties finding the default username and password for a networked Okidata C3400. Turns out is a bit unique, at least in comparison to most default passwords. Hope this helps.

Username: root
Password: the last six of your printer’s MAC address. Do not include dashes and it is case sensitive.

I didn’t verify this, but it wouldn’t surprise me that this password would also work on the other Oki models such as the C3600, C5650, etc.

Hat tip to Daniel.
