Correcting USB Problems

section.
Make sure that your computer is a Windows 8, 7, Vista, XP, or 2000
pre-installed model
Your computer must be a Windows 8, 7, Vista, XP, or 2000 pre-installed model. You may not be able to
install or run the USB printer driver on a computer which is not equipped with a USB port or which has
been upgraded from Windows 95 to Windows Vista, XP, or 2000.
For details about your computer, contact your dealer.

Printer does not work correctly with the USB cable

If your printer does not work correctly with the USB cable, try one or more of these solutions:
❏ Make sure that the cable you are using is a standard, shielded USB cable.
Check whether or not print jobs from other computers are being
printed through the network.
When the print job is executed, the printer or your computer may
have a problem. Check the connection between the printer and
your computer, settings on the printer driver, and settings of your
computer.
When the print job is not executed, network settings may be
incorrect. Ask your network administrator for help.
What to do
On a Windows 7/Vista/XP system with multiple users, a
communication error may occur when switching to a new user
and starting a new print job while the previous user is still printing.
Make sure that the print job for the first user is complete and that
user is logged off before switching to a new user and starting a
new print job.
