Printer Loses Network Settings

Customers experiencing some or all of these problems should upgrade to the x.20.30 firmware level. When a network card is upgraded to x.20.30, all network settings are automatically moved to an unaffected sector of the NVRAM. Note: Because the move is automatic, no network settings (TCP/IP address, host name etc) will be lost.

To update the network card:

Download the latest version of firmware for your print server:
  • Click here and select  Drivers & Downloads.
  • Select  Network Adapters from the list of products and then choose your adapter.
  • Click on Firmware and then download the latest version for your adapter.
  • Follow the directions in the README.TXT document to extract and send the firmware to the network card.
  • If the issues persist after the update, an NVRAM reset may need to be performed. Follow the instructions for resetting the NVRAM below. Warning! The NVRAM reset will erase ALL network settings (including the TCP/IP address) and restore them to the default values. Follow this procedure only as a last-case option. Lexmark is not responsible for any unintended outcome from the procedure. If you have any questions about resetting the NVRAM it or are at all uncomfortable with carrying out this procedure, we suggest you contact your local Technical Support Center for assistance.
  •  If the NVRAM reset does not resolve the issue, please contact the Lexmark Technical Support line.
  • To reset the NVRAM on an INTERNAL network card:

  • Print a Network Settings Page:
    The Network Settings Page contains detailed information on the current settings for all protocols, as well as the connection status and firmware level. It is thus a record of all current network settings. Print this page for informational purposes before resetting the print server's NVRAM.
  • Press the Menu button repeatedly until Network Menu is displayed on the printer's operator panel.
  • Press Select. You should see Network Option # (where # stands for the number of the slot in which the network card has been installed) or STD Network on the display.
  • Press Select.
  • Press the Menu button until you see Network # Setup or STD Network Setup on the display.
  • Press Select. The word Print should now be displayed.
  • Press Select twice to print the network settings page.
  • Keep this page for your records as it contains information that you may need for reconfiguring your network card.
  • Reset the NVRAM

  • Press the Menu button repeatedly until you see Network Menu on the printer's operator panel.

  • Print a Network Settings Page:
  • Press the TEST button briefly and then release it. The network settings page will be printed.
  •  Keep this page for your records as it contains information that you may need to reconfigure your network card. 
  • Press and hold the TEST button for about 10 seconds and release it when all four LEDs are solid. The LEDs should begin the SE Menu light sequence. This menu consists of a repeating count of binary light patterns.
  • When the LEDs indicate a binary three, press the Menu button to enter the NVRAM menu. A binary three pattern is indicated when the third and fourth LEDs are lit up.
  • When the light indicates a binary two, press the Menu button to reinitialize the NVRAM. A binary two pattern is indicated when the third LED is lit up. The adapter should then return to a ready state, with the LEDs scanning across the adapter from left to right and from right to left. This indicates that the NVRAM on the adapter has been reset and must be configured for your network.
