Correcting USB Problems
If you are having difficulty using printer with a USB connection, see if your problem is listed below,
and take any recommended actions.
USB connections
USB cables or connections can sometimes be the source of USB problems.
For best results, you should connect the printer directly to the computer’s USB port. If you must use
multiple USB hubs, we recommend that you connect the printer to the first-tier hub.
Windows operating system
Your computer must have one of the operating systems supported by this printer pre-installed, or be a
model upgraded from Windows 2000, XP, Vista, Server 2003, or Server 2008 to an operating system
supported by this printer. You must not be able to install or run the USB printer driver on a computer
that does not meet these specifications or that is not equipped with a built-in USB port.
For details about your computer, contact your dealer.
