The MF210 is on a different subnetwork and cannot be found

With the printer driver I can specify the IP address in

SANE will <br>
only search the subnetwork by itself and not allow me to

Is there a way that I could get SANE to work with an IP

outside of my network? <br>

Hi, <br>
<br>
Which driver are you using? <br>
scanimage -L <br>
<br>

<br>
I apologize for my ignorance but I thought SANE <i>was</i>
the driver or SANE used some system driver.<br>
The scanner does work when connected to the same subnetwork as
it is detected correctly but it cannot be found when connected
to a different subnetwork. <br>
If I ever installed a driver for the scanner I do not remember
doing so but I would have downloaded it from the official
Canon web site.<br>
I have searched the system hw using hardinfo and other
commands like lshw but cannot find any mention of a driver
that I can identify as relating to the scanner. <br>
What can I do to find out?<br>
</blockquote>
<br>
OK, just realized:<br>
<br>
scanimage -L<br>
device `pixma:MF210_d8492f583058' is a CANON Canon i-SENSYS
MF210 Series multi-function peripheral</blockquote>
<br>
You can put the IP address at the bottom of the file
/etc/sane.d/pixma.conf e.g.<br>
<br>
mfnp://192.168.1.3<br>
<br>
...substituting your device's IP address.<br>
<br>
SANE is really a framework/API and a set of backend drivers for an
array of devices.<br>
Thierry's question was because Canon devices use a number of
different protocols (and therefore backend/drivers) depending on
their age. <br>
In your case, it is using the pixma backend with the mfnp
protocol.<br>
Newer devices require the escl backend.<br>
<br>
According to our supported scanners page here: <br>
<br>
<a class="moz-txt-link-freetext"
href="http://www.sane-project.org/sane-mfgs.html"
moz-do-not-send="true">http://www.sane-project.org/sane-mfgs.html</a><br>
<br>
... the pixma backend is used to support the MF210 for USB, Wifi
and wired Ethernet.<br>
<br>
Cheers,<br>

<br>
Thanks Ralph, I do not quite understand the technical explanation
but I will try editing the pixma.conf file and see if that does the
trick.<br>
