							Locking the control panel menus using the Embedded Web
Server
You can use the control panel lockout functionality to create a PIN and choose specific menus to lock. Each time a locked
menu is selected, the user will be prompted to enter the correct PIN. The PIN does not affect access through the
Embedded Web Server.
To lock control panel menus:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Menu Lockout Setup.
Locking the entire printer
You can use the printer lockout functionality to create a PIN that must be entered in order to use the printer. When
the printer is locked, every print job it receives will buffer to the hard disk. To print the jobs, the user must enter the
correct PIN using the control panel.
Notes:
A printer hard disk must be installed in the printer and working properly for the printer lockout functionality to
be available.
Some data will continue to be processed while the printer is locked. Reports such as user or event logs can be
retrieved from a locked printer.
To lock control panel menus:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Printer Lockout PIN.
Modifying confidential print settings
You can modify confidential print settings using the Embedded Web Server. You can set a maximum number of PIN
entry attempts. When a user exceeds a specific number of PIN entry attempts, all of the jobs for that user are deleted.
You can set an expiration time for confidential print jobs. When a user has not printed the jobs within the designated
time period, all of the jobs for that user are deleted.
Note: This functionality is only available on network printers. Administrative support233

							To modify the confidential print settings:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Confidential Print Setup.
Supporting IPSec
Internet Protocol Security (IPSec) provides authentication and encryption at the network layer allowing all application
and network connections over the IP protocol to be secure. IPSec can be set up between the printer and up to five
hosts, using both IPv4 and IPv6.
To configure IPSec using the Embedded Web Server:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click IPSec.
IPSec supports two types of authentication:
Shared Key Authentication—Authenticates any ASCII phrase shared among all participating host computers. This
is the easiest way to configure when only a few host computers on the network use IPSec.
Certificate Authentication—Authenticates any host computer or subnet of hosts for IPSec. Each host computer
must have a public/private key pair. Validate Peer Certificate is enabled by default, requiring each host to have a
signed authority certificate that is installed. Each host must have its identifier in the Subject Alternate Name field
of the signed certificate.
Note: After a printer is configured for IPSec with a host, IPSec is required for any IP communications to take place.
Supporting SNMPv3
Simple Network Management Protocol version 3 (SNMPv3) allows for encrypted and authenticated network
connections. It also lets a system support person select the desired level of security. Prior to use, at least one user name
and password must be assigned from the settings page.
To configure SNMPv3 through the Embedded Web Server:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click SNMP. Administrative support234
Downloaded From ManualsPrinter.com Manuals 
						

							SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption
Authentication with no encryption
Authentication and encryption
Using 802.1x authentication
802.1x authentication allows the printer to join networks that require authentication before allowing access. 802.1x
port authentication can be used with the WPA (Wi‑Fi Protected Access) feature of wireless printers or print servers to
provide WPA‑Enterprise security support.
Support for 802.1x requires the establishment of credentials for the printer, such as certificates. Certificates provide a
way for the printer to be known to the Authentication Server (AS). The AS allows network access to wireless printers
or print servers presenting a valid set of credentials. You can manage the credentials by using the Embedded Web
Server.
To install and use certificates as part of the credentials:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click Certificate Management.
To enable and configure 802.1x after installing the required certificates:
1Open a Web browser. In the address bar, type the IP address of the printer or print server to be protected using
the format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click 802.1x Authentication. If a wireless internal print server is installed in the printer, click Wireless instead.
Creating an administrative password
Creating an administrative password allows a system support person to password‑protect printer settings. Once a
password is created, it must be entered to access the Configuration and Reports pages of the Embedded Web Server.
An administrative password for the Embedded Web Server must be created before Secure mode can be activated.
1Open a Web browser.
2In the address bar, type the network printer or print server IP address, and then press Enter.
3Click Configuration.
4Under Other Settings, click Security.
5Click Create Password. Administrative support235
Downloaded From ManualsPrinter.com Manuals 
						

							6Type the same password in each Password box.
Changing this setting will cause the print server to reset.
7Click Submit.
Using Secure mode
Secure mode is a way to securely communicate over Transmission Control Protocol (TCP) and User Datagram Protocol
(UDP) ports.
Note: An administrative password for the Embedded Web Server must be created before Secure mode can be
enabled.
To configure Secure mode using the Embedded Web Server:
1Open a Web browser.
2In the address bar, type the network printer or print server IP address, and then press Enter.
3Click Configuration.
4Under Other Settings, click Security.
5Click TCP/IP Port Access.
6Select the Secure Mode Active check box.
Note: If Secure Mode Active is gray or not selectable, create an administrative password and try again.
7Select a setting for each listed port, and then click Submit.
There are three ways to configure the TCP and UDP network ports:
Disabled—Port is disabled and never allows network connections
Secure and Unsecure—Port is always open including when the printer is in Secure mode
Unsecured Only—Port is open only when printer is in Secure mode Administrative support236

							Troubleshooting
Checking an unresponsive printer
If your printer is not responding, make sure:
The power cord is plugged into the printer and a properly grounded electrical outlet.
The electrical outlet is not turned off by any switch or breaker.
The Ground Fault Circuit Interrupter (GFCI) has not tripped.
From the back of the printer, press the GFCI Reset button located above the printer power cord.
The printer is not plugged into any surge protectors, uninterrupted power supplies, or extension cords.
Other electrical equipment plugged into the outlet is working.
The printer is turned on.
The printer cable is securely attached to the printer and the host computer, print server, option, or other network
device.
Once you have checked each of these possibilities, turn the printer off and then back on. This often fixes the problem.
