2. Administrators/Authentication and
Its Application
Administrators
Administrators manage user access to the machine and various other important functions and settings.
When an administrator controls limited access and settings, first select the machine's administrator, enable
the authentication function, and then use the machine. When the authentication function is enabled, the
login user name and login password are required in order to use the machine. There are four types of
administrators: machine administrator, network administrator, file administrator and user administrator.
Sharing administrator tasks eases the burden on individual administrators while also limiting unauthorized
operation by administrators. One person can act as more than one type of administrator. You can also
specify a supervisor who can change each administrator's password. Administrators cannot use functions
such as copying and printing. To use these functions, the administrator must be authenticated as the user.
For instructions on registering the administrator, see "Registering the Administrator", and for instructions on
changing the administrator's password, see "Supervisor Operations". For details on Users, see "Users".
• If user authentication is not possible because of a problem with the hard disk or network, you can use
the machine by accessing it using administrator authentication and disabling user authentication. Do
this if, for instance, you need to use the machine urgently.

User Administrator
This is the administrator who manages personal information in the Address Book.
A user administrator can register/delete users in the Address Book or change users' personal information.
Users registered in the Address Book can also change and delete their own information.
If any of the users forget their password, the user administrator can delete it and create a new one, allowing
the user to access the machine again.
