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:
It's with the ix1500's not 500. I also have an ix100 that works fine.
So for example
/usr/local/bin/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
Looks
Some fujitsu machines have native brightness/contrast support, others
require that a LUT be calculated by the backend and uploaded. I don't think
there is a way to detect which is needed. I will investigate further.

Hi Allan,
Do you know if the iX1500 should respond to —contrast and —brightness ? I'm not
getting any change with those parameters, and no details in the manpage.
—resolution —mode —ald work just fine…
Thx,
Tom
