what makes you say that the values are unchangeable, do you get an error?

Subject: [sane-devel] Avision AV820C Plus flatbed scanner - ADF
In-Reply-To: <[email protected]>

Allan, Ren,
I can't get the ADF to work with this scanner - when I use:
scanimage --device-name=avision:/dev/sg0 --format=tiff --mode="Line Art"
--resolution=200 --source=Normal --batch
it works OK for the flatbed but if I change source to "ADF" or
"Transparency" I get an error message:
scanimage: setting of option --source failed (Invalid argument)
It seems that the software is autodetecting the flatbed and not adding
the extra source mode "ADF"?:
if (dev->hw->feature_type & AV_FILMSCANNER) {
dev->scanner_type = AV_FILM;
dev->sane.type = "film scanner";
}
else if ( BIT(result[62],6) || BIT(result[62],4) ) {
dev->scanner_type = AV_SHEETFEED;
dev->sane.type = "sheetfed scanner";
}
else {
dev->scanner_type = AV_FLATBED;
dev->sane.type = "flatbed scanner";
}
How can I force the scanner to use the ADF?
I did try the scanadf program but that scanned from the flatbed as well.
Thanks,
Phil.
