Maybe you can try to install the ‘sane-airscan’ package.
According to the GitHub documentation :
This backend implements both protocols, choosing automatically between them. It was successfully tested with many devices from Brother , Canon , Dell , Kyocera , Lexmark , Epson , HP , Panasonic , Ricoh , Samsung and Xerox both in WSD and eSCL modes.
This is the package i use for my EPSON network (wifi) scanner, and it works fine !
