Epson WF-7720 want to copy from scan bed but printer defaults to ADF

I want to make an 11 x 17” copy from the scan bed as I don’t want to run the original through the ADF. When I hit Copy, a message pops up telling me to place the document in the ADF. I went through every dang setting and also the PDF of the manual. No matter what setting, the message appears when I hit Copy. Thanks if you can help!
