I see the message Scanner Not Ready or Epson Scan will not start in Windows or on my Mac. What should I do?

  • Try the following:
    • Make sure your product is turned on and securely connected to your computer or USB hub.
    • If your product is connected to a USB hub, make sure it's connected to a first tier hub (the hub closest to the computer) that has its own A/C adapter when more than one hub is connected to the computer.
    • Try restarting your computer.
