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.
  • 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.
