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

• Try one or more of these solutions:
  • Make sure the scanner is turned on and the status light is green.
  • Your system may not work properly if you use a USB cable other than the one that came with your scanner.
  • The scanner may not work properly when connected to the computer through more than one USB hub. Connect the scanner directly to the computers USB port or through one hub only.
  • The scanner may not work properly when your computer is in standby mode (Windows) or sleep mode (Mac OS X). Restart Epson Scan and try scanning again.
  • The scanner may not work properly if you upgrade your operating system but do not reinstall Epson Scan. See Uninstalling Your Scanning Software for instructions on uninstalling Epson Scan. Then follow the instructions on your Start Here sheet to reinstall it.
  • Make sure that Epson Scan is selected in your scanning program. See Starting a Scan With Another Scanning Program for documents and photos or Starting a Scan With Another Scanning Program for film and slides.
  • In the Windows Device Manager, make sure your scanner's name appears under Imaging devices without a question (?) or exclamation (!) mark. If the scanner appears with one of these marks or as an Unknown device, uninstall Epson Scan as described in Uninstalling Epson Scan. Then reinstall it by following the instructions on your Start Here sheet.
  • In Windows, make sure your computer supports USB by following these steps:
    1. Do one of the following:
       
       Windows 7: Click the   Start button icon and select Control Panel. Click System and Security and then System.
       
       Windows Vista: Click the   Start button icon and select Control Panel. Click System and Maintenance and then System.
       
       Windows XP: Click Start and select Control Panel. Double-click the System icon.
       
       Windows 2000: Click Start, point to Settings, and select Control Panel. Double-click the System icon.
    2. Do one of the following:
       
       Windows 7: Click Device Manager.
       
       Windows Vista: Click Device Manager, then click Continue in the User Account Control window.
       
       Windows XP or Windows 2000: Click the Hardware tab, then click Device Manager.
    3. Scroll down and double-click Universal Serial Bus controllers.
       
       If USB Universal Host Controllers and USB Root Hub are listed, Windows supports USB.
