Hello garycardinale,
You will need to call into the support department 1-800-821-2797 they will be able to help you reset the admin password.
I am trying to log in as an administrator for my C400. I use it at home and do not really use the admin for control purposes. I cannot remember the password. I have tried both the 1111 and the printer serial number, but neither works. How do I get into the printer as the admin? I wanted to update the firmware but cannot since I am unable to get in as the admin. Thanks. Gary
