If Basic Authentication, Windows Authentication, LDAP Authentication, or Integration Server Authentication is active, the authentication screen appears on the display. The printer only becomes operable after entering your own login user name and login password.
For SP 4520DN, you need to enter your user code to use the printer if User Code Authentication is enabled.
If you can use the printer, you can say that you are logged in. When you go out of the operable state, you can say that you are logged out. After logging in the printer, be sure to log out of it to prevent unauthorized usage.
Ask the user administrator for the information you need to enter to be authenticated. For details about user authentication, see Security Guide.
User Code to enter on User Code Authentication is the numerical value registered in the Address Book as "User Code".
