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

Overview

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.
