Lexmark 640 User Manual

If the printer is attached to a network, print a network setup page on the printer to verify the network connection. This page 
also provides important information to configure the printer for network printing.

Make sure the printer is on.

Press

Note: If an optional MarkNet™ N8000 series internal print server is installed, Print Net1 Setup appears 

on the display.

Check the first section on the network setup page, and confirm that Status is “Connected.”

If Status is “Not Connected,” the LAN drop may not be active, or the network cable may be malfunctioning. Consult 
a system support person for a solution, and print another network setup page to verify the printer is connected to 
the network.

If the network is using DHCP, an IP address is automatically assigned connecting the network cable to the printer.

Look for the address under the “TCP/IP” heading on the network setup page printed in Printing a network setup 
page.

Go to Verifying the IP settings, and begin with step 2.
