My mother's boyfriend just brought over his Oki C5150n printer, and we hooked it up to my network. The printer is working fine, and I can even access the web interface through the printers IP. The only problem is, I cannot log in. He said he never set a password, so I am trying to find a default username and password for the prtiner, but none of the manuals even hint at such a thing. I searched all over the internet, and I found one guy that said the password is the last 6 digits of the MAC address, but this didn't work. Does anyone know how I can get the default username and password for the web interface?
