Q:
Why can't I start Epson Scan?
A:
Try the following:
  • Make sure the scanner is turned on.


  • Turn off the scanner and computer, then check the USB cable connection between them to make sure it is secure.


  • Connect the scanner directly to the computer's USB port or through one USB hub only. The scanner may not work properly when connected to the computer through more than one USB hub.


  • Make sure your computer meets the minimum System Requirements.


  • If you are using any TWAIN-compliant program, such as ScanSoft PaperPort, make sure that the correct scanner is selected as the Scanner or Source setting.


  • If you upgraded your computer's operating system, you need to reinstall Epson Scan. Uninstall Epson Scan as described in Uninstalling Your Scanning Software, then reinstall it as described on the Start Here sheet.


  • The scanner may not work properly if Epson Scan is open and your computer goes into standby mode (Windows) or sleep mode (Mac OS X). Restart Epson Scan and try scanning again.


  • In Windows, make sure your scanner's name appears under Imaging devices without a (?) or an exclamation (!) mark in the Device Manager window. If the scanner's name appears with one of these marks or as an Unknown device, uninstall Epson Scan as described in Uninstalling Your Scanning Software, then reinstall it as described on the 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.

    3. Scroll down and double-click Universal Serial Bus controllers.



      If USB Universal Host Controllers and USB Root Hub are listed, Windows supports USB.
