You add the SANE_DEBUG_* variables for the backends you want to debug.
In your case, you probably want to look at least at SANE_DEBUG_DLL and
SANE_DEBUG_NET and the backend that supports your particular scanner.

Please read the systemd documentation. I vaguely seem to remember all
the Environment "assignments" are run together by systemd, though.
# Disclaimer: I no longer use systemd.
> What is
An environment variable that tells the dll (and most other backends)
where to look for their configuration. See sane-dll(5).
> SANE_DEBUG_BJNP=5, and
Environment variables that tell each of the backend how much to log.
Larger values produce more output. What and how much exactly differs
Hope this helps,
