[sane-devel] Fujitsu fi-4120Cdj errors (repeat)

[m. allan noah]

update: i hard-set the gamma byte (0x29) to 0x80, and the paper byte 
(0x35) to 0xC0, and then forced the lines:

 set_WD_paper_width_X (buffer, s->page_width);
 set_WD_paper_length_Y (buffer, s->page_height);

to always run, and the scanner runs.

but now, the output images from the program 'scanadf' are truncated.

any ideas?
