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
