Your printer may need to re-establish network communication if: 

  • You received a replacement printer.

  • You replaced your router or access point.

  • You performed a complete reset of your router or access point.

  • You changed your router's network name or security passphrase.

  • You are moving the printer to a new network that uses a different network name and security passphrase.

  • You have reset the printer network settings back to the factory defaults; to verify, the SSID value on the network settings page displays print server ######, where ###### is the last 6-digits of the UAA(MAC) address.

  • You have exhausted all efforts to eliminate a  Wi-Fi indicator light.

  • You have a Wi-Fi indicator light; for example, you have decided to switch from a USB connection to a wireless network connection.


Before you begin

If... Then...
You received a replacement printer... See Related Configuration Articles for Windows and Apple computers.
You know your network's wireless configuration settings... See the Procedure below.
You have already joined the printer to the wireless network, but you cannot print... See Step 7.
You are uncertain of your network's wireless configuration settings...

See Printer/Network Configuration Requirements below, and then see the Procedure.


Printer/Network Configuration Requirements


IMPORTANT! Lexmark is not responsible for these settings. Please consult the person responsible for setting up your wireless network, the router's documentation, or the router manufacturers other technical support resources for additional assistance.

Step Action

Make sure you have the following wireless settings:

  • Network name (SSID)
  • Security Mode/Type (WEP, WPA, WPA2) Note: WPA2 is highly recommended.
  • Security key or passphrase. Important! This value is sensitive to capitalization, spaces, symbols and spelling. Improper entry of this value will lead to configuration failure.
  • Optional: Radio channel (1–14) is only useful when manually configuring an older wireless printer or All-In-One.
Exceptions! None or no passphrase is valid if you have an Open or unsecured network. Also, WPS users really only need to know the network name of their network.

If you are unfamiliar with any of the settings above, click here for an article that provides an example procedure. 

Comments and warnings:

  • You will need your configured Username and Password to open your router's web configuration page.
  • Or, you will need the router manufacturer's default Username and Password to open your router's web configuration page.
  • If any setting values have been forgotten, you will have to perform a complete reset of the router(Access Point).
  • If a complete reset of the router (Access Point) is performed, you will need to reconfigure all settings mentioned above.
  • You will have to reconfigure your wireless MAC or PC clients to rejoin your wireless network.
  • You will have to reconfigure the printer to rejoin your wireless network.
 3 Make sure the host computer from which you are performing this procedure is communicating with the access point.

Microsoft Windows XP,Vista, 7, and 8 Procedure: Lexmark Wireless Setup Utility(WSU) Location


There are two methods to access the Wireless Setup Utility:

    • Click Unlisted Network or Manually enter network information, and then enter the information that you verified under Printer/Network Configuration Requirements.

      CAUTION! If the latter option is considered, it is probable that configuration will fail due to factors such as signal strength or other wireless variables.
