[sane-devel] Configure the scanner of Canon i-SENSYS MF4380dn via network

[Stefan Greim]

Hello,

i switched some weeks ago from Windows to Ubuntu 16.04 LTS and I have 
some trouble using my scanner of Canon i-SENSYS MF4380dn via network.
I installed the printer driver from this site: 
https://www.canon-europe.com/support/consumer_products/products/fax__multifunctionals/laser/laserbase_mf_series/i-sensys_mf4380dn.aspx?type=drivers&language=EN&os=LINUX 
The printer is working as expected.
After that I added this the Sane Repository as described here: 
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git
I added to the file /etc/sane.d/pixma.conf: "bjnp://192.168.2.199" 
(which is the ip of the canon device) and tried to find the scanner via 
"sane-find-scanner" and "scanimage -L", but that did not work.

The results are:
~$ sane-find-scanner

   # sane-find-scanner will now attempt to detect your scanner. If the
   # result is different from what you expected, first make sure your
   # scanner is powered up and properly connected to your computer.

   # No SCSI scanners found. If you expected something different, make 
sure that
   # you have loaded a kernel SCSI driver for your SCSI adapter.

   # No USB scanners found. If you expected something different, make 
sure that
   # you have loaded a kernel driver for your USB host controller and 
have setup
   # the USB system correctly. See man sane-usb for details.

   # Not checking for parallel port scanners.

   # Most Scanners connected to the parallel port or other proprietary ports
   # can't be detected by this program.

   # You may want to run this program as root to find all devices. Once you
   # found the scanner devices, be sure to adjust access permissions as
   # necessary.



and:

~$ sudo scanimage -L

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).


I found several different repos, versions etc. of sane. Some posts wrote 
about different configurations etc. I already tried this to: 
http://lists.alioth.debian.org/pipermail/sane-devel/2014-April/032283.html
Additionally I opened the ports 8610 and 8612 as inbound and outbound 
via "sudo iptables -A IN/OUTPUT -p udp --dport 8610/8612 -j ACCEPT"

I would say that I am technically adept (at least a bit) but I am very 
new to linux. Is there somebody who could help me out and could describe 
some steps I could try to get this scanner working? I have no clue how 
to go ahead...

best regards,
Stefan
