2. Authentication and its Application
The Management Function
The machine has an authentication function requiring a login user name and login password. By using the
authentication function, you can specify access limits for individual users and groups of users. Using access
limits, you can not only limit the machine's available functions but also protect the machine settings and
files and data stored in the machine. For instructions on changing the administrator's password, see
2
"Supervisor Operations".
• If you have enabled [Administrator Authentication Management], make sure not to forget the
administrator login user name and login password. If an administrator login user name or login
password is forgotten, a new password must be specified using the supervisor's authority.
• Be sure not to forget the supervisor login user name and login password. If you do forget them, a
service representative will have to return the machine to its default state. This will result in all data in
the machine being lost and the service call may not be free of charge.
