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 XP, Vista, 7, 8, Server 2003, Server 2008, or Server 2012 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.
