Description Fredrik Persson 2005-08-03 13:23:58 UTC
My scanner, a Plustek OpticSlim 2400, works with scanimage (the cmdline tool)
but not with xsane or kooka. 

This is what I get when I use the command line 'scanimage' program:

As you can see, no problem there.

However, both xsane and kooka fails miserably!

Reproducible: Always
Steps to Reproduce:
Use xsane or kooka to make a preview scan with a Plustek OpticSlim 2400

Actual Results:  
The preview image looks like this: (example)

Expected Results:  
It should have showed a proper preview like scanimage does: (example)

I checked the sane-backends sources and noticed that the sane-backends sources
are patched by the ebuild to include version 1.0-67, whereas they usually
contain version 1.0-66. At least that's what I think, I'm not very experienced
with portage.

However, I saw this in the changelog for the gt68xx sources:

V 1.0.68 (2005-05-07)

* Plustek OpticSlim 2400: Fixed list of resolutions. That fixed the
  preview. Removed "untested" warning. Adjusted scan area.
* Updated gt68xx.TODO.

I compiled a new .so-file with sane-backends 1.0.15 patched with gt68xx sources
1.0-71, and the problem was fixed.

So... I humbly ask the maintainer to patch the sane-backend sources with gt68xx
sources version 1.0-71 instead of 1.0-67, and the Plustek OpticSlim 2400 will
work. Thanks in advance.

I'm reassigning this bug to phosphan right away, since his name is all over the
sane-backends ChangeLog file.

Even worse, my name is in metadata.xml :-)

Made a patch for the latest gt68xx version (build 71) from SANE CVS and checked
in as .15-r3 - this way I won't ever get this stable before .16 is out :-)

Please test and re-open this bug if necessary.
Comment 4 Fredrik Persson 2005-08-04 08:08:44 UTC
Great! It works, thanks!

(Two things that may interest you... 

1. I had the SANE_BACKEND variable set to "gt68xx" when I first emerge -r3, and
that caused scanimage -L NOT to find the scanner anymore. sane-find-scanner did,
though. Since scanimage -L didn't find anything, neither did kooka or xsane.

I removed the SANE_BACKEND variable (thereby increasing the time it took to
build the package substantially, of course) and that fixed the problem. I guess
this is not how it is supposed to be.

2. When the scanner aquires a preview with -r3, it makes a loud CLICK sound when
the head reaches the end of the scanner bed.

I've never heard this click sound before, not with 1.0.15, nor with my homebuilt
vanilla-sane-backend-sources-patched-with-gt68xx 1.0-71.

I don't like the click, it really doesn't sound healthy.

I'll close this bug, you think I should open another bug report one about the
click sound?)
Comment 5 Fredrik Persson 2005-08-04 08:18:07 UTC
More about that "click" thing...

Only kooka does it, not scanimage nor xscan.

Definitely not. I already had some similar report (bug #90598), but was unable
to find any difference between all(?) relevant files when building with or
without SANE_BACKENDS. 
Could you perhaps build both versions for your configuration (using "noclean"
FEATURES and copying the build directory somewhere) and check what's different?
That would be really helpful.

Since I don't have such a scanner (and no CLICK therefore) I would be interested
why it is like that. When you look at the ebuild you see all modifications done
to the original sources. I know it is time consuming, but please try to find out
what's going on there.

It is indeed possible to damage scanner hardware with faulty backends.

Would be nice - as well as commenting on the other bug about SANE_BACKENDS if
you've got something new.
