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 your connection type. See the steps below:
    1. Make sure the product is turned on.
    2. Do one of the following:
       • Windows 8.x: Navigate to the Apps screen, 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).
       • OS X: Open Applications > Epson software, then double-click EPSON Scan Settings.
    3. If you see a EPSON Scan cannot be started window, click No. The window may appear twice.
    4. Make sure the correct scanner is selected.
    5. Do one of the following:
       • If the product is connected to your computer with a USB cable, make sure the Connection setting is set to Local, then skip the remaining steps.
       • If the product is set up on a network, make sure the Connection setting is set to Network and your scanner appears under Network Scanner Address with the correct IP address. If these settings are correct, skip the remaining steps. If the IP address for your product does not appear, go to the next step.

         
         
         

         Note: If you don't know your product's IP address, you can print a network status sheet to obtain it.

    6. Click Add.

       
       
       

    7. Select the IP address that appears in the list. If more than one IP address appears, be sure to select the one that matches your product's IP address.

       Note: If you have a firewall or Internet security software installed, the search feature may not work correctly. In this case, click Enter address and enter the IP address manually.

    8. Click OK.
