Canon MF3010 : finds scanner, but no scanners indentified

Did you install the debs from the Canon website. They do make debs for some of their products.
Have you tried both xsane and simple scan?
Did you try running them with gksudo to test if permissions are the issue?

Greetings,

- for Canon MF3010 Ubuntu provided own debs for the printer only (Canon MF3010 ver.2.7); since the printing if fine, I did not install any packages from the Canon web

- I tried both xsane (0.998-5ubuntu1) and simple-scan (3.10.0-0ubuntu1) with and without gksudo (or sudo); still scanner is not detected

- I belong to group scanner: groups ilias
ilias : ilias adm dialout fax cdrom floppy tape dip video plugdev fuse lpadmin admin sambashare scanner

- list of files: /.ls /etc/sane.d/
canon_dr.conf fujitsu.conf gt68xx.conf saned.conf
dll.d/ genesys.conf kodakaio.conf xerox_mfp.conf
~/.ls /etc/sane.d/dll.d/
empty

(sudo) sane-find-scanner:

sudo scanimage -L

No scanners were identified.

What is strange that /etc/sane.d belonging to the libsane package of sane-backends is reporting plenty of conf-files in the synaptic package property, like

.
.
.
/etc/sane.d/canon.conf
/etc/sane.d/canon630u.conf
/etc/sane.d/canon_dr.conf
/etc/sane.d/canon_pp.conf
.
.
but in fact only few conf-file are present in /etc/sane.d directory as I mentioned above.

Well, friends, so-far no help.

The Canon MF3010 scanner is detected as USB-device: "sudo sane-find-scanner" and "sudo lsusb" give ID 04a9:2759.

However, "sudo scanimage -L" says "No scanners were identified".

I have the new set ppa-packages installed for sane-backends (scanimage (sane-backends) 1.0.25git; backend version 1.0.25). No libraries of lower version. Also I checked the page http://www.sane-project.org/README.linux (I did not install sane-backends manually).

What could be wrong ? Why is this scanner not detected ?

I have Ubuntu 13.10: 3.11.0-14-generic #21-Ubuntu SMP Tue Nov 12 17:04:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux.

Best, M.

Hi again,

neither newest 1.0.25-git20131219-saucy0 packages are working; at least I am providing output from some commands:

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).

========================================================

Now I realized that my second scanner, Epson Stylus SX 400, is not working ! Previously with lower version of packeges (provided by Ubuntu 13.10) it worked fine.

 So, there must be something inherently wrong in ppa of libsane, libsane-common and sane-utils. Please try it with Cannon, Epson scanners....

BTW, why there is no conf file in /etc/sane.d/ ?

Hi again,

following email communication (from December 2013) with Olaf, I got the clues for solving the problem:

I installed the "iscan + iscan-data" packages from the Epson support web-page, and got the (USB-connected Epson) scanner working with simple-scan and xsane.

Best, Miro

Thank you Miro for your kind help. Installing drivers from Epson support page solved my problem completely.
