OK I have installed their package. I have Linux Mint, so Ubuntu-based
distro.

It seems to install correctly and the 2 backends (kyocera and
kyocera_gdi_a3) seem to be loaded up. You can test this with
SANE_DEBUG_DLL=3.

Diag from the backends can be got with SANE_DEBUG_KYOCERA and
SANE_DEBUG_KYOCERA_GDI_A3:

Obviously I don't see anything detected because I don't have one of these
devices.
Not really sure what the difference between these two backends is or which
one is expected to work with your device.

Perhaps you could try generating some diag output from their backend when
attempting to scan?

Cheers,
Ralph
