ADF with a Flatbed Scanner
  1. Turn off the scanner power
  2. Re-seat the ADF cable by unplugging then replugging the cable
    • The ADF cable is the short cable that runs from the top of the scanner to the base of the scanner
    • This cable is not plugged prior to packaging. It must be plugged in after removing the scanner from the box
    • This cable is how the ADF gets its power for scanning
  3. Toggle the lock switch firmly 4 times leaving the scanner in the unlocked (open padlock) position
    • For the Visioneer 9450, 9650, 9750 and Xerox DocuMate 510, 515, 520 the lock is located on the bottom of the scanner base
    • For the Visioneer Patriot 680, 780 and Xerox DocuMate 632 the lock is located on the side of the scanner base
  4. Unplug the USB cable from both the scanner and the computer then plug the USB cable back in again
    • Do not use a USB cable longer than 6 feet
    • Do not use a USB extension cable
    • If plugged into a USB hub or keyboard, try plugging the scanner directly into the back of the computer
  5. Turn the scanner power back on
    • Try plugging the scanner directly into the wall
    • The low power output from a UPS battery backup can cause incorrect hardware errors to be reported
