My scanning software doesn't work properly in Windows or on my Mac. What should I do?

• If your scanning software does not operate correctly, try these solutions:

  • Make sure your computer has adequate memory and meets the system requirements for your operating system.
  • Make sure your computer is not running in a power-saving mode, such as sleep or standby. If so, wake your system and restart your scanning software.
  • Make sure the product is turned on.
  • Make sure the scanning software is installed.
  • Make sure the connection between the product and your computer is secure.
  • If you upgraded your operating system but did not reinstall your scanning software, try reinstalling it.
  • In Windows, be sure that the product is listed under Imaging Devices in the Device Manager.
  • Check that the correct product is selected using the Epson Scan 2 Utility.
  • Connect the product directly to the computer. The product may not work properly when connected through a USB hub/switch.
  • If you are using a TWAIN-compliant program, make sure that the correct product is selected as the Scanner or Source setting.
  • Check that the Wi-Fi connection is working correctly. Try turning the wireless router off and on (ES-C320W/RR-400W).
  • Make sure another computer is not connected to the product using a USB cable. A USB connection takes priority over a Wi-Fi connection. If another computer is connected by USB, disconnect it. (ES-C320W/RR-400W)
  • If you are using a Mac computer, make sure you select the network that has priority on it. (ES-C320W/RR-400W)
