# When Machine Functions are Restricted

When a machine function is restricted, only authorized users are able to use that function.

Depending on the restricted function, users will be authenticated from the machine's control panel or in the printer/LAN-Fax driver.

- When print jobs are restricted, you can only authenticate through the PCL6 printer driver. Printing from the PostScript 3 printer driver will not be possible.

- User restriction settings can be used in combination with LDAP authentication, except for printing using the PCL6 printer driver and sending LAN-Faxes. Under LDAP authentication, users will only be able to authenticate for PCL6 printing and LAN-Faxes using user names and passwords for the LDAP server, not user codes for the user restriction settings.

The table below shows the functions that can be restricted, and how users can be authenticated to use those functions.

Restricted function | Authentication method
--- | ---
Copying Sending faxes Scan to E-mail/FTP/Folder Scan to USB | The machine requests for a user code when a user presses the [Start] key. The user must enter a valid user code from the control panel.
Printing Sending faxes via LAN-Fax | The user must enter a valid user code in the printer or LAN-Fax driver before executing a print command.

Authenticating through the control panel

When the machine requests for a user code, enter a user code (within 30 seconds) using the number keys.

If you enter a wrong user code 3 times, the machine beeps and denies the authentication.

Press the [OK] key.

Authenticating through the printer or LAN-Fax driver

Open the file you want to print on your computer.

Open the printer driver's properties.

Click the [Valid Access] tab (PCL6 printer driver) or check the [User Code] check box. (LAN-Fax driver).

Type the user code using 1 to 8 digits, and then click [OK].

Execute a print command.

If an incorrect user code is entered, the job will be canceled automatically.

- You cannot enter the user code if the [User Authentication] (PCL6 printer driver) or [User authentication] (LAN-Fax driver) check box on the [Advanced Options] tab of the driver's properties is checked. Clear the check box if necessary.
