Hi,If you could come this far, create a new user for authentication as "admin" set a pin and password but make sure you do not link any id or pin to it. Use that user credentials at the Remote UI login!! Cheers...
Alright, I just faced the same issue with my machine and I had to do some modifications.From the copier, if you have access to the administrator login, log in to the same (default pin is 7654321). Go to Settings/Registration and choose Device setting...
