No expert, but user of the epson backend, if you check the epson backend
source a button function is present.

When using xsane -> view -> advanced options there is a "wait for
button" when enabled you have to press a button on the scanner.
For me (epson 1660 photo has four buttons) i push on the "start" button
or the "scan to email" the scanner starts.
