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.

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 
cer tificate.
Note:After an MFP is configured for IPSec with a host, IPSec is required for any IP 
communication to take place.

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.
6Indicate the setting for each sub-item as required for the network environment.
7Click Submit.
Confidential Print Setup
Confidential Print Setup allows the designation of a maximum number of PIN entry attempts and 
allows setting an expiration time for print jobs. When a user exceeds a specific number of PIN entry 
attempts, all of that user’s print jobs are deleted. When a user has not printed their jobs within a 
designated time period, the print jobs are deleted. To activate Confidential Print Setup:
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 Security.
4Click Confidential Print Setup.
5Set the value for the maximum number of invalid PINs allowed. Set Job Expiration to the 
maximum amount of time before a submitted confidential print job is deleted.
6Click Submit.

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 format: 111.222.333.444. To indicate an 
entire subnet, provide the subnet mask bits in the format: 111.222.333.0/24.

Clearing jams
By carefully selecting print media and loading it properly, you should be able to avoid most paper 
jams. For more information on avoiding paper jams, see Avoiding jams. If jams do occur, follow the 
steps outlined in this section.
To resolve the paper jam messages, you must clear the entire paper path, and then touch Continue 
to clear the message and resume printing. The MFP prints a new copy of the page that jammed if 
Jam Recovery is set to On or Auto; however, the Auto setting does not guarantee the page will print.
Identifying jams
If the MFP jams, the appropriate jam message will be displayed on the touch screen Print status 
message bar.
See the diagram on page 147 for an overview of the paper path and areas where jams may occur. 
The path varies depending on the MFP paper sources.

Access doors and trays
The following illustration shows the path that print media travels through the MFP. The path varies 
depending on the input source (trays, multipurpose feeder, envelope feeder) you are using.
The numbers in following the illustration indicate the numbers that can appear on the control panel 
and designate the general area of a paper jam.
CAUTION:Floor-mounted configurations require additional furniture for 
stability. You must use either a printer stand or printer base if 
using a 2000-sheet drawer. Certain other configurations also 
must have a printer stand or printer base. More information is 
available on our Lexmark Web site at www.lexmark.com/
multifunctionprinters.

Understanding jam messages
The following table lists the jam messages that can occur and the action necessary to clear the 
message. The jam message indicates the area where the jam occurred. However, it is best to clear 
the entire paper path to ensure you have cleared all possible jams.
Clearing jams
Paper jams can occur in three areas: the front of the MFP, inside the MFP, and at the rear of the MFP. 
Jams in the front of the MFP occur in the input options or the duplex tray. Jams inside the MFP occur 
in two locations and require the removal of the print cartridge. Jams can also occur at the rear of the 
MFP or duplex unit.
Note:The following clearing jam instructions may seem out of numerical sequence. 
However, they have been grouped to help you quickly clear the print path. To go to 
a specific jam, see Understanding jam messages.
250 Paper Jam Check MP Feeder
1Remove the paper from the multipurpose feeder.
2Flex, fan, and restack the media, and place it into the multipurpose feeder.
