I bought a Xerox Phaser 7800 used, which has admin credentials set up on it. I've attempted the Reset NVRAM function which failed for reasons I'm not sure of (wiped all of my print settings, but admin credentials remain intact). I've attempted logging in with both password 1111 and the device's serial number which both don't work.
I bought this printer for personal use in a residential location, so I would prefer to not have to call out a service technician. Any insight is much appreciated, thanks
