[sane-devel] Canon MF746Cx not working under OpenSUSE

[Andreas Croci]

Thank you very much for your reply.

I tried the first of you solutions, but it didn't work. I clicked on
"Expert Download" and it offered me a few more options, among other LEAP
15.5. I downloaded that and it saved a "sane-airscan.ymp". I
right-clicked on it and it offered me to 1-Click-install it with YAST.
That's what I did, but it failed installing the repositories
"SUSE:SLE-15-SP1:GA" through "SUSE:SLE-15-SP5:GA". The installation
failed. I repeated the process and this time it said the installation
(of "sane-airscan") was successful.

But scanning still doesn't work. In the directories "/etc/sane.d" and
"/etc/sane.d/dll.d" there are the files "airscan.conf" and "airscan" 
respectively, but "scanimage -L" gives:

"[13:58:00.608002] [bjnp] add_scanner: Scanner MF745C/746C is not
supported, model is unknown! Please report upstream

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages)."

basically the same as before.

"sudo airscan-discover -d" gives:

"airscan-discover: symbol lookup error: /usr/lib64/libtiff.so.6:
undefined symbol: jpeg12_write_raw_data, version LIBJPEG_8.0"

A "sudo zypper refresh" says:

"Retrieving repository 'SUSE:SLE-15-SP2:GA' metadata
...................................................[error]

Skipping repository 'SUSE:SLE-15-SP2:GA' because of the above error."

and the same for SP1, SP3, SP4 and SP5.

Now I'm more out of clue than I was before.
