Updating the printer firmware via the Embedded Web Server (EWS)


This article explains how to perform printer firmware update through the Embedded Web Server (EWS).

Note:  EWS update cannot be done with a USB cable connection. This procedure must be performed with the printer connected via an Ethernet cable to the network. It is not advisable to do this wirelessly (for wireless-capable devices) since a wireless connection is susceptible to data loss and interference. Data loss could damage the printer during a firmware update.

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.


  1. Download the latest firmware and extract it to a certain location on the PC (preferably the Desktop).

    Note:  Check this article for steps on how to download the latest printer firmware.

  2. Access the printer EWS by typing the printer IP address into the URL field of your browser (e.g., Internet Explorer, Mozilla Firefox, Google Chrome, Safari).

    For example, enter http://MFP_IP_Address, where MFP_IP_Address is the IP address of the printer.

  3. Click Settings and Update Firmware.

  4. Click Choose File > Go to the location of the file (preferably the Desktop) > Select the file > Click Open.

  5. Click Submit.

  6. The printer displays a message that it is updating the firmware.

    Warning—Potential Damage:  Do not interrupt the firmware update. After completion, the printer should return to a Ready state.
