I can't start Epson Scan in Windows or on my Mac. What should I do?

    If you cannot start Epson Scan, try these solutions:

    • Make sure your scanner is turned on and any interface cables are securely connected at both ends.
    • Make sure Epson Scan is selected in your scanning program.
    • Make sure your computer is not running in a power-saving mode, such as sleep or standby. If so, wake your system and restart Epson Scan.
    • If you connected the scanner using a USB cable, make sure it is connected directly to your computer or through only one USB hub.
    • Check the connection setting and test the connection using Epson Scan Settings:
      • Windows 8.x: Navigate to the Apps screen and select EPSON Scan Settings. Click the Test button.
      • Windows (other versions): Click or Start > All Programs or Programs > EPSON > EPSON Scan > EPSON Scan Settings. Click the Test button.
      • OS X: Open the Applications folder, click Epson software, and click EPSON Scan Settings. Click the Test button.
    • Make sure you do not have multiple versions of Epson Scan installed. If you do, uninstall both versions and install one version.
    • If you upgraded your operating system but did not reinstall Epson Scan, try reinstalling it.
    • If you cannot start Epson Scan in Full Auto Mode, your original may have a very dark or bright background, or be very large. Try scanning in another Epson Scan mode instead.
