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.
