[sane-devel] Fujitsu Backend

Fri Feb 14 22:29:47 GMT 2020

Yes, I mistyped- the backend should auto detect the need for LUT on the
ix1500 too. I'll note that your example command lines have weird emdashes
before the contrast and brightness, not a proper double dash. Any chance
that is related?

If not, can you get a debug log like so:

SANE_DEBUG_FUJITSU=35 scanimage --mode=gray --contrast=20 --brightness=20
--format=tiff --ald=yes  --device-name=fujitsu:ScanSnap\
iX1500:94839  --resolution=200  --batch=Scan-Designer-TAWS27-144246-%d.tif
2>ix1500.log

then compress ix1500.log and send it to me directly?
