Before you begin
Note: Firmware update is essential to optimize the performance of the printer. However, this procedure must only be performed when Lexmark Technical Support has recommended a firmware update. Recommendations are made by a technician when updating the printer firmware corrects a printer function or a printing anomaly.
Do the following before updating printer or MFP firmware:
- Make sure that the printer is in a “READY” state or in an “Invalid Engine Code” state.
- Double check for any option cards installed on the printer. If an option card installed, check whether there is an updated firmware version use that instead.
Warning—Potential Damage: Do not update the firmware 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.
