[sane-devel] Calibrate Xerox travel scanner 100? (sane-genesys)

[Fred Fowler]

Hi.  I'm using Ubuntu LTS 12.04 with libsane 1.0.22-7ubuntu1 to scan with a
Xeroc travel scanner 100.  The image quality is terrible with a very dark
image.

I'm trying to calibrate the scanner with the following command:

$ scanimage  -d genesys:libusb:001:008 --calibrate

I feed the calibration sheet through the feeder, and then I get the
following message:

scanimage: setting of option --calibrate failed (Operation not supported)

It looks like --calibrate is not available, although in the sane-genesys
backend documentation it says that calibration is "available".

Also using the "advanced" window in xsane there is a calibrate button, but
when I use it the same failure message is displayed.

Can anyone point me in the right direction?

Also, I have a Xerox travel scanner 150 as well.  Is there any chance that
it might be supported?  Currently scanimage -L doesn't recognize it.

Any help would be greatly appreciated!

Thanks,

--Fred
