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

• Try the following:
  • Make sure the CX5800F is turned on and securely connected to your computer or USB hub.
  • If the CX5800F is connected to a USB hub, make sure it's connected to a first tier hub (the hub closest to the host computer) when more than one hub is connected to the computer.
  • Try restarting your computer.
  • Make sure you installed all the software correctly. See Install Software.
