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. Make sure the correct Connection setting is selected, then click the Test button.
    • Windows (other versions): Click or Start > All Programs or Programs > EPSON > EPSON Scan > EPSON Scan Settings. Make sure the correct Connection setting is selected, then click the Test button.
    • OS X: Open the Applications folder, click Epson software, and click EPSON Scan Settings. Make sure the correct Connection setting is selected, then 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.
