You want skanpage installed. it does multi page scan and OCR, on Ubuntu a default installation with the requirements.
also you need airscan installed
sudo zypper in sane-airscan skanpage
for OCR install tesseract files.
you might want to use yast - software and search for sane and skanpage to find all options.
then to detect the scanner, deactivate the firewall, open skanpage and find the scanner.
then activate the firewall again.
