Make sure your scanner’s AC adapter is securely connected to the scanner and a
working electrical outlet.
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.
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
for details.
If Windows still has problems recognizing your scanner, make sure your computer
supports USB. See
Checking For Windows USB Support
