2Enter the defined password in the Print Faxes Password field. 
This releases any received and held fax jobs, so they print. 
Note:The defined password was created in step 6 of Setting a password before printing received faxes.
Setting security using the Embedded Web Server (EWS)
To enhance the security of network communications and MFP configuration, use the advanced security features. These 
features are available through the Web page of the MFP.
Setting the Advanced Password
The Advanced Password is used to password-protect the menus. Setting the Advanced Password is required for Secure 
Mode and confidential communication with MarkVision Professional. 
If the Advanced Password was not created using the touch screen control panel by following the instructions in Setting 
Password Protect for the menus on page 127, it can also be created from the EWS. To create it:
1Open a Web browser. In the address line, enter the IP address of the MFP being configured using this format: 
http://ip_address/.
2Click Configuration.
3Under Other Settings, click Security.
4Click Create/Change Password.
5Click Create/Change Advanced Password.
6Enter and reenter a password of both alphabetic and non-alphabetic characters. The password must be a 
minimum of 8 characters.
7Touch Submit.
Using the secure EWS
The SSL (Secure Sockets Layer) allows for secure connections to the Web server within the print device. To connect to the 
EWS more securely, connect 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 MFP. 
To connect to the SSL port:
1Open a Web browser.
2In the address line, enter the IP address of the MFP being configured 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 EWS of the MFP:
1Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click SNMP.

Administrative support
SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption
Authentication with no encryption
Authentication and encryption
Note:The selected level serves as a minimum level of protection. The MFP negotiates with the SNMPv3 
requestor, and a higher level of protection may be agreed upon and used by both.
5Indicate the setting for each sub-item as required for the network environment.
6Click Submit.
Disabling SNMPv1 and SNMPv2
1Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click SNMP.
5Click to clear the Enabled check box unless SNMPv1 and SNMPv2 are used in this environment.
6Click Submit.
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 MFP and up to five hosts, 
using both IPv4 and IPv6. To configure IPSec through the EWS: 
1Open a Web browser. In the address line, enter the IP address of the MFP being configured 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. The certificate authority certificate must be installed. Each host must have its identifier in the Subject 
Alternate Name of the signed certificate.
Note:After an MFP is configured for IPSec with a host, IPSec is required for any IP communication to take 
place.
5Indicate the setting for each sub-item as required for the network environment.
6Click Submit.

Administrative support
Disabling ports and protocols
The TCP and UDP ports can be configured to one of three modes or values:
 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 MFP 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 mode for TCP and UDP ports from the EWS:
1Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click TCP/IP Port Access.
5For each port listed, select the appropriate value from the list previously described.
Note:Disabling ports will disable function on the MFP.
6Click Submit.
Using 802.1x Authentication
802.1x port authentication allows the MFP 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 MFP. The MFP 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 MFPs presenting a valid set of 
credentials. The credentials can be managed by using the EWS of the MFP. To use certificates as part of the credentials:
1Open a Web browser. In the address line, enter the IP address of the MFP being configured 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 EWS after installing the required certificates:
1Open a Web browser. In the address line, enter the IP address of the MFP being configured 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.
5Select the check box next to Active to enable 802.1x Authentication.

							Using the restricted server list function
135
Administrative support
Using the restricted server list function
The Restricted Server List lets a system support person restrict which hosts are allowed to communicate with the MFP over 
the network which prevents other hosts from managing and printing to the MFP.
Note:The Restricted Server List only restricts TCP traffic; it does not affect UDP traffic. The Restricted 
Server List supports up to ten host addresses or ten network addresses.
To configure the Restricted Server List from the EWS of the MFP:
1Open a Web browser. 
2In the address line, enter the IP address of the MFP requiring configuration using the format: http://ip_address/.
3Click Configuration.
4Under Other Settings, click Network/Ports.
5Click TCP/IP.
6Enter the list of addresses in the Restricted Server List field for network communications permission separated 
by commas in the following for mat: 111.222.333.444. To indicate an entire subnet, provide the subnet mask bits in 
the format: 111.222.333.0/24.

Incorrect characters 
print.You are using an 
incompatible parallel 
cable.If you are using a parallel interface, make sure you are using an 
IEEE 1284-compliant parallel cable. We recommend Lexmark part 
number 1329605 (10 ft) or 1427498 (20 ft) for the standard parallel 
port.
The MFP is in Hex Trace
