If the printer is attached to a network, then print a network setup page to verify the network connection. This page also provides important information that aids network printing configuration.
From the home screen, navigate to:
> Reports
> Network Setup Page
Check the first section of the network setup page, and confirm that the status is Connected.
If the status is Not Connected, then the LAN drop may not be active, or the network cable may be malfunctioning. Consult a system support person for a solution, and then print another network setup page.
