I am unable to scan from my computer. What should I do?

• Try the following:
  • Make sure your CX6400 is turned on and securely connected to your computer or USB hub.
  • If your your CX6400 is connected to a USB hub, make sure it's connected to a first tier hub. The first tier hub is the hub closest to the host computer when more than one hub is connected to the computer.
  • Check to make sure no lights are flashing on the device. You cannot scan when any light is flashing.
  • Try restarting your computer.
