Visioneer RoadWarrior Scanner [Sane]

[Andrew Charnley]

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 correct sheet. I made one using: http://www.fixya.com/support/t17003105-calibration_sheet_visioneer_roadwarrior and the errors went away

This is 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. 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.

Can you attach ~/.cache/simple-scan/simple-scan.log after doing a black scan (or run simple-scan --debug). This will show the information that SANE is reporting with this scanner. It does sound like a driver issue though.

[Andrew Charnley (snoopy20)]

It is, I reported it but the driver doesn't have a maintainer.

I have the same scanner.
I tried a couple of scanning programs, one of them gave a 5 char cal file, like this one here.
simple-scan did not like it either.

Another program had a gui with a calibrate function and it coughed up a 65k file, it seems to work for simple scan as well.

Try xscan.

[mike (mweisman07)]

err, not "xscan", but "XSane"

[mike (mweisman07)]

Here is my cal file for this scanner, feel free to examine it.

[Andrew Charnley (snoopy20)]

Interesting, I also used xsane and had the same 5 char calibration file . I'll stick yours in it's place and see if I get output.

[Andrew Charnley (snoopy20)]

I managed to get some type of output at 600dpi (unusable but it's there).

Can I ask;

1. which calibration sheet are you using?
2. version of xsane?

Regards,

Andrew

I used the calibration sheet that came in the box with the used scanner.
(Found at a charity thrift store for $3USD :-) )

It's a white bar with three black arrows indicating direction, a big white space, followed by a black space. The whole thing is approx. half of a US letter-sized sheet.

xsane v. 0.999

[Expired for simple-scan (Ubuntu) because there has been no activity for 60 days.]

Same problem in Ubuntu 18.04 LTS. Works fine in Win10 and is all black in Linux. The difference though: The light isn't enabled in Linux. The white light is on in Windows, but there is only a dim red light only in Linux.
