The Scanner is Not Recognized by Your System
First check your connection to the scanner and computer:
❏ Make sure your scanner’s power cord is securely connected
to the scanner and a working electrical outlet, and the
scanner’s power button is turned on.
❏ Make sure the interface cable is securely connected to the
scanner and your computer, and that the cable is not damaged
or crimped.
❏ Your system may not work properly if you use a USB cable
other than the one that came with your scanner, so try using
that cable.
❏ The scanner may not work properly when connected to the
computer through more than one USB hub. Connect the
scanner directly to the computer’s USB port or through one
hub only.
❏ Check to see if your computer system meets the requirements
for the scanner interface you are using. See "System
Requirements" on page 170 for details.
❏ If Windows still has problems recognizing your scanner,
make sure your computer supports USB. See "Checking For
Windows USB Support" on page 144 for instructions.
