[sane-devel] Help. Any Ideas?

[Peter Talbott]

I'm hoping someone could help me with this.

My OS: kubuntu 14.04 amd64
My scanner is wired on my home network:
     Canon MF230
     IP 172.16.184.25/24 (set static IP)

Printing works fine. Scanner will not detect with sane.
here is the debug output:

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).

root at UbuntuLaptop:/etc/sane.d# scanimage -V
scanimage (sane-backends) 1.0.26git; backend version 1.0.26
root at UbuntuLaptop:/etc/sane.d#
root at UbuntuLaptop:/etc/sane.d# more /proc/version
Linux version 3.13.0-105-generic (buildd at lgw01-59) (gcc version 4.8.4 
(Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #152-Ubuntu SMP Fri Dec 2 15:37:11 UTC 
2016

I've compiled and installed the git sane-backened, I've tried specifying 
the device in pixma.conf with all different syntaxes of:
root at UbuntuLaptop:/etc/sane.d# more pixma.conf
# pixma.conf configuration for the sane pixma backend
#
# define URI's of scanners (one per line)
# This is only used for network scanners.
# normally scanners will be detected by sending a broadcast
# if this does not work under your OS, or if the scanners
# are on a different subnet, configure your scanners URI here
#
# method must be bjnp
# port number can normally be left out, port 8612 is used as default
# Example:
# bjnp://myscanner.my.domain:8612
# bjnp://printer-1.pheasant.org
#

#bjnp://172.16.184.25:8610

#bjnp://172.16.184.25

#mfnp://172.16.184.25

Now where it has the hash '#' I've added them back in because it didn't 
do any good specifying them, it just took longer to run scanimage -L
It looks to me that [bjnp] automatically finds the scanner, identifies 
the scanner and adds it but pixma_find_scanners() found 0 devices.

I am totally out of ideas, any help would be great!
Thank you
Pete
