One of the following network-related situations is observed:
Where to begin
It is important to differentiate between communication failure and print failure.
you are not sure that the printer is communicating over the network
see the following Network Communication Diagnosis topics.
you have confirmed network connectivity

you require additional assistance with the Topics in this article
consider other help options, including contacting Lexmark Technical Support.

*Printers and MFPs equipped with Wireless (IEEE 802.11b/g/n) option cards.
Before you begin:
Advanced users should answer the following questions:
Note: Autonegotiate (AutoN) requires that both devices be set to auto.
I. Preliminary Communication Tests
continue your diagnosis with Topic 2 and the remaining topics as necessary.
go back to the top of the article and consider the Where to begin suggestions again.
see Before you begin just above this table and start your diagnosis at Topic 8.
connect the printer to a known working network cable or network access port.
Open a web browser session to access it.
Type http://printer_IP_address, where printer_IP_address is the TCP/IP address of the printer or MFP. This value is located on the network settings page located under TCP/IP.
Verify that you can access different sections of the printer or print server's embedded web server.
Note: The article title in the sample references the Lexmark C500n, but the procedure is almost identical for all printers.
II. Other factors that can prevent network printer/MFP function or communication
Access the printer web page (embedded web server).
Click Links and Index.
Click TCP/IP Port Access.
Enable ports if necessary.
Try to find the IP address causing the issue by opening a web browser session. To do this, type http://printer_IP_address, where printer_IP_address is the TCP/IP address of the printer or MFP. Repeat this procedure from multiple clients if necessary.
Identify the TCP/IP address of the client machine. Click Settings > Network/Ports > TCP/IP > Restricted Server List. Remove the IP address and click Submit.
Note: RSL can also be configured from a telnet session, UNC, or MVP device policy with products released after 2003.
Note: This setting is found in the printer SE Menu under MAC > Set Card Speed for those network administrators who know how to access this menu.
III. Wireless Topics
6,9, 12,15,24,36,48,54 Mbps
Note: You can run the Wireless Setup Utility to re-establish communication with the wireless router/AP.
Note: You can connect the print server via USB cable to the client or host computer and you must know the network name (SSID) of your network, the encryption method, and the security/network key or passphrase.
