Sorry for the delay.
It turns out, that the MF8230 has max resolution 300dpi from ADF and 600
dpi from Platen Glass, see attached screenshots.
So there is no work here - except possibly to error this condition and
abort operation.
I'll check again to see, if everything else seems to be working. I think it
does.
