How to Install and Set the ETHERFAX License File
This tutorial provides instructions on how to install the ETHERFAX License file onto your Lexmark MFD.
Info, Notes and Warnings
Newer Lexmark MFDs will often have the ETHERFAX License file installed by default.
The indication that the ETHERFAX license file is installed is found in the Fax Transport toggle. Should the etherFAX option be available, these instructions will not be needed.
To start receiving fax messages, you must first have a route procured to your account and assigned to your Lexmark device.
The latest firmware must be installed for these steps to work. If it is not, please use the Lexmark Support page here to look up instructions on your device.

Ending Notes and Details
