Hi,
Can you send us a picture of the scan at 1200 dpi ?
Did you try higher resolutions ?
You may have the same kind of problem I had with my Canon MP990 (and
which I solved, I have to send the patch for that BTW !)
Bye.

Hi,
today I activated my brand new Canon PIXMA MG6450 printer/scanner. In
the SANE
table for supported devices the device is listed as "Untested":
...
PIXMA MG6400 Series USB 0x04a9/0x1770 Untested Testers
needed!
...
I built and installed the sane-backends project. It worked like a charm
for my
device which is connected by wifi. The scanned image looks quite good.
The
colors are correct. Resolutions up to 600dpi are working. With 1200dpi
there are
"column oriented" artefacts.
Configuration on printer: Normal configuration process, then
- wifi config (dhcp)
- set hostname (to "canon") through the printers display menu
Configuration on system (Ubuntu trusty):
To /etc/sane.d/pixma.conf added line:
bjnp://canon.local
Building sane-backends (default):
./configure
make
sudo make install
$ scanimage -L
device `pixma:MG6400_canon.local' is a CANON Canon PIXMA MG6400 Series
multi-function peripheral
Do you need more informations?
regards,
Chris.
