Issue Description:

Firmware Update Utility (FUU) is one of the methods used to update the printer firmware. This can be performed via any of the following connection types; local (USB), ethernet, or wireless.

IMPORTANT! Firmware update is essential to optimize the printer’s performance. However, this procedure should only be performed when Lexmark Technical Support has recommended a firmware update.
Recommendations will be made by a technician if a printer function or printing anomaly is known to be corrected by updating the printer firmware.

Before you Begin

Do the following before updating printer firmware:

  • Make sure that printer is in a “READY” state, and no error codes or messages are displayed on the printer screen.
  • Double check for any option cards installed on the printer; should the printer have an option card installed, please check whether
    there is an updated firmware version for the said option card and make use of that instead. 

WARNING! Do not update code if you are unsure about the presence of special code or code that is specific to a Downloadable Language Emulator (DLE). For more information, contact Lexmark Technical Support.
