Notes:
• Your port may be working fine, but certain conflicts can occur with multiple USB devices. Try disconnecting
one of your other USB devices.
• If the USB port on the computer is not working, then try using the other USB ports on the computer.
MAKE SURE THE USB CABLE IS WORKING
Try using a different USB cable. If you are using a cable longer than 10 feet, then try using a shorter cable.

disconnecting these devices so that your printer is directly connected to your computer.

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.
