Setting security using the Embedded Web Server (EWS)
You can enhance the security of network communications and device configuration by using the advanced security options. 
These features are available through the Web page of the device.
Setting the system password
Setting the system password protects configuration of the Embedded Web Server. A system password is also required for 
Secure mode and confidential communication with MVP.
To set the system password:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http: //ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Create Password, if one has not been set previously. If a password has already been set, click Change or 
Remove Password.
Using the secure Embedded Web Server
The SSL (Secure Sockets Layer) allows for secure connections to the Web server within the print device. You can connect 
to the Embedded Web Server more securely by connecting to the SSL port instead of the default HTTP port. The SSL port 
connection will encrypt all Web server network communications between the PC and the printer. To connect to the SSL 
port:
Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format: 
https: //ip_address/.
Supporting SNMPv3 (Simple Network Management Protocol version 3)
SNMPv3 protocol allows for encrypted and authenticated network communications. It also lets the administrator select a 
desired level of security. Prior to use, at least one user name and password must be established from the settings page. To 
configure for SNMPv3 through the Embedded Web Server of the printer:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click SNMP.
SNMPv3 authentication and encryption has three levels of support:

Administrative support
•No authentication and no encryption
•Authentication with no encryption
•Authentication and encryption
Note:Only the selected level and later may be used to communicate.
Supporting IPSec (Internet Protocol Security)
IP Security protocol provides authentication and encryption of communications at the network layer allowing all application 
and network communications 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 through the Embedded Web Server: 
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click IPSec.
Two types of authentication are supported for IPSec:
• Shared Key Authentication—Any ASCII phrase shared among all the participating hosts. This is the easiest way 
to configure when only a few hosts on the network use IPSec.
• Certificate Authentication—Allows any hosts or subnet of hosts to authenticate for IPSec. Each host must have 
a public/private key pair. Validate Peer Certificate is enabled by default, requiring each host to have a signed 
certificate and the authority certificate must be installed. Each host must have its identifier in the Subject Alternate 
Name of the signed certificate.
Note:After a device is configured for IPSec with a host, IPSec is required for any IP communication to take 
place. 
Using Secure mode
You can configure the TCP and UDP ports to one of three modes:
• Disabled—Never allows network connections to this port.
• Secure and Unsecure—Allows the port to remain open, even in Secure mode.
• Unsecured Only—Allows the port to only open when the printer is not in Secure mode.
Note:A password must be set to enable Secure mode. Once enabled, only the ports set to Secure and 
Unsecure will be open.
To configure the Secure mode for TCP and UDP ports from the Embedded Web Server:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click TCP/IP Port Access.
Note:Disabling ports will disable function on the printer.

Using 802.1x Authenticating
802.1x port 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 an optional internal wireless print server to 
provide WPA-Enterprise security support.
Support for 802.1x requires the establishment of credentials for the printer. The printer must be known to the Authentication 
Server (AS). The AS will allow network access to devices presenting a valid set of credentials which typically involves a 
name/password combination and possibly a certificate. The AS will allow network access to printers presenting a valid set 
of credentials. You can manage the credentials by using the Embedded Web Server of the printer. To use certificates as 
part of the credentials:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click Certificate Management.
To enable and configure 802.1x on the Embedded Web Server after installing the required certificates:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click 802.1x Authentication.
Note:If an optional internal wireless print server is installed, click Wireless instead of 802.1x 
Authentication.
Locking the operator panel menus
Operator Panel Menu Lockout lets you create a PIN number and choose specific menus to lock. Each time a locked menu 
is selected, the user will be prompted to enter the correct PIN at the operator panel. The PIN does not affect any access 
through the EWS. To lock operator panel menus:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
format: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Menu Lockout Setup.

							Using the Coverage Estimator
85
Administrative support
Using the Coverage Estimator
The Coverage Estimator provides you with an estimate of the percent coverage of cyan, magenta, yellow, and black toner 
on a page. These estimates are printed on the page.
To turn on the Coverage Estimator utility:
1Make sure your printer is on.
2Press   on the operator panel.

The Coverage Estimator utilizes an algorithm that counts pixels for each toner color: black, cyan, magenta, and yellow. 
Once the utility is turned on, the printer prints the percent coverage for each color on each page of the job.
The Coverage Estimator is only intended to estimate the coverage on a given page. For all toner colors that are used, the 
minimum percentage that prints is 2 percent. Reported values may vary from printer to printer. The accuracy of the 
estimates may be affected by how full the print cartridges are, environmental conditions, the media type, the software 
application, software settings, the driver, driver settings, and the content of the page. Lexmark makes no claim as to the 
accuracy of the estimated percents.

Administrative support
Configuring printer alerts
You can configure the printer several ways to let you know when it requires attention.
Using the Setup Menu
Selecting Auto Continue may affect how the printer alerts execute. This setting defines how long the printer waits after 
displaying a message before it resumes printing.
Using MarkVision Professional
MarkVision™ Professional, the network printer management utility, indicates when it is time to replace supplies and points 
out actual or potential problems. When a printer needs attention, it alerts the network administrator with a detailed graphic 
of the printer showing the cause for the alert (for example, an empty paper tray). For more information about MarkVision 
Professional, refer to the Software and DocumentationCD that shipped with your printer.
Using MarkVision Messenger
MarkVision Messenger lets you create Actions that execute specific commands whenever messages like Tray x Missing 
or 88 Toner Low appear on the display. For example, you can create an Action that sends an e-mail to the administrator 
when the printer runs out of paper.
Actions can be set up to occur automatically, as well as conditionally or repeatedly. For more information about MarkVision 
Messenger, refer to the Software and DocumentationCD that shipped with your printer.
