Troubleshooting 164

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.

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.

RECONNECT THE PRINTER POWER SUPPLY

1Turn off the printer.

Note: Make sure the printer is not in Sleep mode. Press and hold for three seconds to turn off the printer.

2Unplug the power cord from the wall outlet, and then pull out the power cord from the power supply.

3After one minute, reconnect the power cord into the power supply, and then plug the power cord into the wall outlet.

4Turn on the printer.

RUN THE INSTALLER AGAIN

1Close the installer.

2Remove the CD, and then restart the computer.

3Insert the CD, and then run the installer again.

MAKE SURE YOUR COMPUTER IS ABLE TO ACKNOWLEDGE USB ACTIVITY ON THE USB PORT

Open the Device Manager to check if it has activity whenever a USB device is connected to a USB port:

1Click , or click Start and then click Run.

2In the Start Search or Run box, type devmgmt.msc.

3Press Enter, or click OK.

4Watch the Device Manager window while connecting a USB cable or another device to the USB port. The window refreshes when the Device Manager recognizes the USB connection.

•If there is activity on the Device Manager but none of the previous solutions worked, then call customer support.

•If there is no activity on the Device Manager, then there may be a problem with your computer and its USB support. The computer must recognize the USB connection in order for installation to work.
