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.
Note:
❏ Your computer must support USB 2.0 in order to use it as an
interface.
❏ Since USB 2.0 is fully compatible with USB 1.1, USB 1.1 can be
used as an interface.
❏ USB 2.0 is applied for Windows XP, 2000, and Server 2003
operating systems. If your operating system is Windows Me or 98,
use USB 1.1 interface.

problems. Try one or both of these solution:
For best results, you should connect the printer directly to the
computer’s USB port. If you must use multiple USB hubs, we
recommended that you connect the printer to the first-tier hub.
Cause What to do
