This article explains how to perform printer firmware update through File Transfer Protocol (FTP).

IMPORTANT! FTP update cannot be done with USB cable connection. This procedure should 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, during firmware update, cause damage to the printer. 


Before you begin

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 should updating the printer firmware be known to correct a printer function or printing anomaly.

Do the following before updating printer or MFP firmware:

    • Download the .zip file to an easy-to-find location such as your Windows Desktop. NOTE: Click here to view how to download the latest printer firmware.

    • If you do not have a copy of WinZip, download this application to enable you to extract or expand the firmware file.

    • Using WinZip, expand the file to your Windows Desktop or a destination directory that is easy to locate.

    • Make sure that printer is in a “Ready” state or in an “Invalid Engine Code” state.

    • 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.

    • Make sure that you have a working printer object

WARNING! 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.

Note: You can type the word “put” first then drag the file towards the command prompt window; this should show you the exact location of the file.

If the UNC command (path to the location of the file) contains a space, make sure to enclose the UNC path with double quotes (“).


Press Enter.

Note: This should send the firmware file over to the printer.


The printer will display a message that it is updating the firmware.

Warning! Do not interrupt the firmware update. After completion, the printer should return to a Ready state.
