Try using a different USB cable. If you are using a cable longer than 10 feet, then try using a shorter cable.

Note: USB hubs, extension cables, port replicators, and docking stations may cause connection issues. Try disconnecting these devices so that your printer is directly connected to your computer.

MAKE SURE YOU ARE USING THE CORRECT CD FOR YOUR PRINTER MODEL

Compare the printer model on the CD to the printer model on the printer. The numbers should either match exactly or be within the same series.

If unsure, look for an updated version of the printer software on the Lexmark Web site. For more information, see the printer User's Guide.
