Support Scanners WorkForce Series Epson WorkForce ES-400

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 scanner is turned on.
    • Make sure the connection between the scanner 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 scanner is listed under Imaging Devices in the Device Manager.
    • Connect the scanner directly to the computer. The scanner may not work properly when connected through a USB hub.
    • If you are using a TWAIN-compliant program, make sure that the correct product is selected as the Scanner or Source setting.
    • If you are using the scanner with the optional Network Interface Unit, make sure the network cable is securely connected.
    • If your scanner is connected to one computer via USB and another computer via wireless connection, and Epson Scan 2 is running on the wirelessly connected computer, pressing the  start button on the scanner will save the scanned images to the wirelessly connected computer (ES-500W/ES-500WR).
