Point to check
Is the machine power
on?
Can your computer use
a USB connection?
Solution
When a USB cable is connected,
make sure the power of the machine is
"ON" and then connect a USB cable to
the machine. When the machine is not
powered on, switch on the main power
switch and the [POWER] key (
that order.
Check your computer whether or not a
USB interface can be used on the
Device Manager in your computer.
(For information on "Device Manager",
see Help in Windows.)
If USB can be used, your controller
chipset type and root hub will appear
in "Universal Serial Bus controllers" in
"Device Manager". (The items that
appear will vary depending on your
computer.)
If these two items appear, USB should
be useable. If a yellow exclamation
point appears next to "Universal Serial
Bus controllers" or the two items do
not appear, refer to your computer
manual or check with the manufacturer
of your computer to enable USB and
then reinstall the printer driver.
