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

Here are the steps on how to update 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
).
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

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.
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
.

Procedure

  1. Download the latest firmware and extract it to a certain location on the PC (preferably the Desktop).
    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.
  4. Click
    Choose File
    > Go to the location of the file (preferably the Desktop) > Select the file > Click
    Open
    .
  6. The printer displays a message that it is updating the firmware.
    Do not interrupt the firmware update
    . After completion, the printer should return to a
    Ready
    state.
