Yes.
Looks like you already have a config for option "preview" in your 
scanbd.conf, make a similar entry for other (promising) options, e.g. 
"button-wait", "mode", ...

Then restart scanbd and watch the output:

i) look if the option is found and an action is installed for this option

ii) look for value changes if you make some actions on the scanner, e.g. 
pressing buttons, changing mode-switches and things like that ...

Sorry, but i don't know the scanner and I don't have access to this 
model, therefore this is a little bit like poking in the smog ...
