This is not normal, by default it shouldn't be 0.
I'll correct it, but I have to reproduce it.

scanimage: rounded value of br-x from 0 to 0
scanimage: rounded value of br-y from 0 to 0


./frontend/scanimage -d 'escl:http://192.168.23.130:80'

scanimage: rounded value of br-x from 0 to 0
scanimage: rounded value of br-y from 0 to 0

All options specific to device `escl:http://192.168.23.130:80':
Scan mode:
--mode Gray|Color [Gray]
Selects the scan mode (e.g., lineart, monochrome, or

color).

--resolution 75|100|150|200|300|600dpi [75]
Sets the resolution of the scanned image.
--preview[=(yes|no)] [no]
Request a preview-quality scan.
--preview-in-gray[=(yes|no)] [no]
Request that all previews are done in monochrome mode.  On

three-pass scanner this cuts down the number of passes to

one

and on a
one-pass scanner, it reduces the memory requirements and
scan-time of
the preview.
Geometry:
-l 0.0846558..215.9mm [0]
Top-left x position of scan area.
-t 0.0846558..297.011mm [0]
Top-left y position of scan area.
-x 0.0846558..215.9mm [0]
Width of scan-area.
-y 0.0846558..297.011mm [0]
Height of scan-area.

@Till: indeed. I had to install the autoconf-archive. It solved

So I un-plugged the 2 printers, stopped the 2 and restarted

only

the

Canon. I can heat the printer moving but I get the same error:
scanimage: sane_start: Invalid argument

please note that I do that on my "backends" folder, which I got

from

that: git clone https://gitlab.com/sane-project/backends.gitI

also

have a sane-escl folder which I got from the link you sent

before but

there is no "scanimage" there.

sane-escl is archived
Please test this :
$ scanimage -d 'escl:http://192.168.23.130:80' -x 215 -y 296 -T

I have cloned the backend repo:

Applied the patch (Changed 1200 to 600 and added the last

param).


And now I'm trying to follow the instructions there:
https://help.ubuntu.com/community/CompileSaneFromSource

running ./autogen.sh failes right from the beginning :( I

prints

thousands of lines "patch: **** Can't create file

./ltmain.sh.orig

: Too

many open files" I increased my limit to 10k files, but I'm

getting the

exact same error. I tried to checkout the 1.0.29 but got the

same

error.


after investigations it seems coming from the lack of

autopoint.

apt-get

install solved it.

I tried to run configure with this command:
./configure --prefix=/usr --libdir=/usr/lib/

--sysconfdir=/etc

--localstatedir=/var  --enable-avahi

But it failed:
./configure: line 14868: syntax error near unexpected token

`noext,'

./configure: line 14868: `AX_CXX_COMPILE_STDCXX_11(noext,

optional)'


If you are on Ubuntu, you need to install the

"autoconf-archive"

package.
