Reset OKI C831 Web Administrator password without knowing current passsword
We have an OKI C831 Colour laser printer that we cannot change any of the settings to.
The default username and password should be admin/aaaaaa . This worked fine for 3 setting changes and ever since we cannot get back into the console. The printer is set on a static IP and we can browse the web interface with no problems. We cannot enter the administration area without the password. OKI support say we need to have an engineer come out onsite and reset the NIC card to factory with a manufacturer tool.
Does anyone know how we can reset this without an onsite visit. We have no problems with the printer being set back to default settings and having to start again.
The control menu on the printer also requires a password to reset, so we are locked out via web and menu console on printer.
We have tried root and admin logins. Both with aaaaa or 000000 or the last 6 digits on MAC address. remembering the admin/aaaaaa combination works for some changes.
Also worth noting was that after every config change the printer went back to a 169. address, even when a DHCP server was present. The configuration tool would find it one time and not the next. Very strange. The firewall was set to allow for public and private networks.
