My computer does not recognize the product when I use a USB connection. What should I do?

• After installing the scanner software, make sure you restarted your computer. If restarting your computer does not solve the problem, try the following:

  • Make sure the scanner is turned on.
  • Disconnect your scanner from your computer, then reconnect it.
  • Make sure the connection mode switch is set to the correct connection type (RR-70W only).
  • If you use a USB hub, connect the scanner directly to the computer.
  • Make sure to use the USB cable that came with the scanner.
  • Try using a different USB port on the computer.
