Hi All,

I just picked up one of these portable scanners, it works well in
Windows.

In Linux and either xsane or simple-scan however it always scans a
completely black page.

Thinking it was a calibration issue I ran:-

SANE_DEBUG_GENESYS=255 scanimage -d genesys --calibrate 2>calibrate.log

Which at first reported it couldn't find the black bars on the sheet. I
made one using: http://www.fixya.com/support/t17003105-calibration_shee
t_visioneer_roadwarrior and the error resolved.

The calibration value "01 e8 00 00 00" is written. There is still an
error in the log but it appears to be OK given it writes the file.

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

I'm unsure if it's calibration anyhow as it worked OK-ish in Windows
(washed out, but had an image).

Scans are still completely black, unsure what to try next?

calibrate.log file can be found: https://bugs.launchpad.net/ubuntu/+sou
rce/simple-scan/+bug/1712663

Further, it's picking up the correct size, cropping et all. Shame it's
entirely black. In GIMP I can see all pixels are #000000 so I doubt
it's calibration after all.

Hi All,
I just picked up one of these portable scanners, it works well in
Windows.
In Linux and either xsane or simple-scan however it always scans a
completely black page.
Thinking it was a calibration issue I ran:-
SANE_DEBUG_GENESYS=255 scanimage -d genesys --calibrate
2>calibrate.log
Which at first reported it couldn't find the black bars on the sheet. I
made one using: http://www.fixya.com/support/t17003105-calibration_sh
ee
t_visioneer_roadwarrior and the error resolved.
The calibration value "01 e8 00 00 00" is written. There is still an
error in the log but it appears to be OK given it writes the file.
scanimage: setting of option --calibrate failed (Operation not
supported)
I'm unsure if it's calibration anyhow as it worked OK-ish in Windows
(washed out, but had an image).
Scans are still completely black, unsure what to try next?
calibrate.log file can be found: https://bugs.launchpad.net/ubuntu/+s
