Your scanner isn't supported by SANE. I suppose you're using
Canon's
<br>
ScanGear driver. Please ask Canon for technical support.
<br>
<br>
Maybe somebody else can help with your xsane issues.
<br>
<br>
Hope this helps.
<br>
<br>
Cheers,

<br>
<br>
My system is Ubuntu 18.04.2 with a new Canon Pixma TS6220,
which
<br>
replaces an HP Photosmart 6520.
<br>
All of the following comments refer to my new Canon printer.
<br>
Xsane with my recently retired HP works perfectly (except, I
think
<br>
the Canon images are the better).
<br>
<br>
1) I am able to move the dashed lines to frame the print to be
<br>
scanned, but the output always contains the images of what
ever is
<br>
on the platen on a "full size" white background.
<br>
2) I have selected “inches” as the unit of measurement, but
the
<br>
preview window has “px” in the upper left corner, and the
<br>
dimensions in the windows at the bottom of the main menu are
in
<br>
pixels. These dimensions do not change as I adjust the frame
of the
<br>
photo to be scanned and always read 2480*3507*24 (24.9MB).
<br>
3) There are no length markings along the side or top of the
preview
<br>
window.
<br>
4) In Advanced Options, the UOM displays “px”. The sliders
<br>
change as I adjust the frame, but for a 4” x 6” photo in the
<br>
upper left corner, the lower right corner is shown to be
.00235x,
<br>
.00154y.
<br>
5) For all resolutions > 75 ppi, the scanned image of the
photos is
<br>
very dark/saturated – beyond my ability to correct.
<br>
6) Max scan resolution in the main menu is only 300, whereas
it is
<br>
1200 with the HP scanner.
<br>
<br>
This printer is WiFi equipped, but I am using it with a usb
<br>
cable as my pc and printer are on the 2nd floor of our house
while
<br>
the router and my wife’s pc are on the 1st floor. I am willing
to
<br>
help out in the testing of your Pixma backend if I can be of
any
<br>
assistance.
<br>
<br>
Kind regards,
<br>
<br>
Bill

Bonsour,
<br>
I find it unfortunate that the backend pixma does not take input
usb-id.
<br>
The pixma driver supports all printer scanners:
<br>
canon pixma ts and canon pixma mg.
<br>
Currently you have to add it directly in the code.
<br>
Here is the patch that allows sane to operate to scan.<br>
