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.
    • Make sure Epson Scan is set up correctly for a USB connection. See the steps below:

      1. Make sure the product is turned on.
      2. Do one of the following:
        • Windows 8: Navigate to the Start screen, right-click the screen, select All apps, then select EPSON Scan Settings.
        • Windows (other versions): Click Start or , and select Programs or All Programs. Select EPSON Scan > EPSON Scan Settings (or EPSON, then EPSON Scan, and then EPSON Scan Settings.)
        • Mac: Search for EPSON Scan Settings, then click EPSON Scan Settings to open it.
      3. If you see the screen below, click No. The screen may appear twice.



      4. Make sure the correct scanner is selected.
      5. Make sure the Connection setting is set to Local.
