[sane-devel] Canon PIXMA MG5550

[François Charlier]

Hi,

I recently bought a Canon PIXMA MG5550 which is detected by scanimage as 
an "MG5500 Series" device:

> naz at tapioca:~$ scanimage -V
> scanimage (sane-backends) 1.0.24; backend version 1.0.24
> naz at tapioca:~$ scanimage -L
> device `pixma:MG5500_83A6A0000000' is a CANON Canon PIXMA MG5500 Series 
> multi-function peripheral

I'm currently using this device "connected" through wifi, didn't test 
using USB connection.

`scanimage -T` reports passed tests at all resolutions.

- Scanning at 75 dpi, 150 dpi, 300 dpi and 600 dpi generate a correct 
image.
- Scanning at 1200 dpi generates a messed-up image (see example outputs 
at [1]).

I generated some example output [1] with the following command:

> for res in 75 150 300 600 1200;
>   do scanimage --progress -l 50 -t 0 -x 50 -y 100 --format pnm 
> --resolution ${res}dpi > Canon_Pixma_MG5550_${res}dpi.pnm
> done

If I can be of any help testing some fix for the 1200dpi scan, just tell 
me how.

Cheers !
