what is the problem?

When I connect a USB cable between the printer and my computer, an “Unknown Device” message appears.

If you are using Windows 2000, the “Unknown Device” message does not mean that there is a problem. However, if you are using Windows 98, Me, or XP, the “Unknown Device” message does mean that there is a problem. Use the troubleshooting steps below.

possible causes...

Static electricity has built up in the cable between the printer and your computer.

You may have a defective USB cable.

to solve the problem...

1.Disconnect the USB cable from the printer.

2.Unplug the printer from its power cord.

3.Wait approximately 30 seconds.

4.Plug the power cord into the printer.

5.Plug the USB cable into the printer.

6.Replace the USB cable or use a parallel cable if “Unknown Device” continues to appear in the New Hardware Found dialog box and you are not using Windows 2000.
