Hi MrsMolly,
Thanks for visiting Apple Support Communities.
Web Services for Devices or Web Services on Devices (WSD) is a Microsoft API to enable programming connections to web service enabled devices, such as printers, scanners and file shares. In this quick lesson from TheMacU.com see how to use the Image Capture App that is built into every Mac to scan photos or documents.Learn much more about usi.
I see you're trying to scan from your new Epson All-In-One printer/scanner in OS El Capitan. If you connect the scanner to your Mac using a USB cable, you can scan using the Image Capture application. For more help with this, see the instructions in Mac Basics: Using a scanner.
If you're using the scanner wirelessly or over a network, you can check the following Epson page for setup and help information: Epson America, Inc. - Support: OS X El Capitan Support
Sincerely.
