Getting Help When Things Go Wrong 4
When I connect a
USB cable between the
printer and my computer,
an “Unknown device”
message appears.
• Static electricity has built up
in the cable between your
computer and printer.
OR
• You may have a defective
USB cable.
1 Disconnect the USB cable from your
printer.
2 Unplug the printer from its power cable.
3 Wait approximately 30 seconds.
4 Plug the power back into the printer.
5 Plug the USB cable back into the printer.
6 If “Unknown device” continues to appear in
the “New hardware found” dialog, replace
the USB cable or use a parallel cable.
When I connect a
USB cable between the

the “New Hardware Wizard”
message did not appear.
You may not be using
Windows 98. Make sure Windows 98 is running and your
computer is connected using a USB cable. If
you do not have Windows 98, you need to use
a parallel cable.
You may not have USB
enabled. 1 In Windows 98, click Start Settings
Control Panel .
2 Double-click the System icon.
3 Click the Device Manager tab.
4 Click the plus ( + ) icon next to the Univer-
sal Serial Bus Controller option. If you see
a USB host controller and a USB root hub
listed, USB is probably enabled. If you do
not see these devices listed, refer to your
computer’s documentation or contact the
manufacturer for more information on
enabling and setting up USB.
5 If you cannot enable USB, you can always
use a parallel cable to connect your printer
to your computer.
Your USB cable may not be
connected properly. 1 Disconnect and then reconnect the USB
cable from your printer.
2 Make sure that it is securely attached.
