[sane-devel] Canon LiDE 700F flatbed scanner

[Canie Adams]

Hi,

I have been unable to get my Canon 700f to work with Ubuntu 12.04. I've 
tried all the tricks and tips I could find with no success.  As far as I 
can tell I'm running all the latest and greatest.  I found where Matus 
Sabo requested assistance and I'll include your exchange below.  His 
description is exactly what I'm seeing.  Xsane fails with "Invalid 
Argument" as well as scanimage -T.  sane-find-scanner finds the scanner 
as well as scanimage -L.  The device is in the rules file and I can see 
it as root or user.  I just cant scan. When I get the "invalid argument" 
the device number is deleted and shows up again with the next sequential 
number.  System log only shows that a new device was found.  I'd really 
like to get this working as I love Gimp but the Windows version crashes 
regularly but the Ubuntu version can't use the scanner.  Help!!

/      Hello,

      something didn't work like you expected. There is no 'WARNING' in
current git source tree. You can check it by setting debug before
running the same commands with:
export SANE_DEBUG_GENESYS=255

The debug messages should report a '1.0 build 2302' version if latest
version is ran.

Since SANE 1.0.23 is about to be released, I think PPA for this release
will be available soon. It may be a matter of a week or two.

Meanwhile, you could check the libsane-genesys.so.1.0.23 library is
present in /usr/lib/sane or in /usr/lib64/sane (on 64bits systems). Also
check that you don't have both subdirectories.

Regards,
      Stef

Thanks,
Canie Adams
