tl_x=50. 50 what? I mean, which unit? It's similar to your last
problem with the string list for "ADF". Not all options are
SANE_TYPE_INT. In this case it's a SANE_Fixed option so you must use a
fixed-point type. See the SANE-Standard for details.

That works, because the reolution option is an int option.
