First thing to do, you need to replace ippusbxd package with ipp-usb. It 
works MUCH more reliable. Om a next version of Ubuntu it would happen 
automatically, but for now you should do it by yourself.

Prebuild ipp-usb packages can be loaded from here:

https://download.opensuse.org/repositories/home:/pzz/

And project page is located here:

https://github.com/OpenPrinting/ipp-usb

After that, there is a good chance that the sane-escl driver will work 
with your scanner. If it won't, you may consider installing sane-airscan 
driver from here:

https://download.opensuse.org/repositories/home:/pzz/ (binary packages)
https://github.com/alexpevzner/sane-airscan (project page)

It will also come automatically with the never version of Ubuntu, but 
not with 20.04
