Halftone does not work with the 3091 because the driver doesn't
implement it. 
Lineart returns black & white images (1bit/pixel). If the image is
inverted you might try to set the RIF (reverse image format) option.
In file fujitsu.c function setWindowParam you can find the following
  if (s->model == MODEL_3092)
      set_WD_rif (buffer, SANE_TRUE);
      set_WD_rif (buffer, s->reverse);

You can try the same for MODEL_3091.
