Hello,

I am using sane 1.0.24.

USB test :
I linked my sanner to my computer via USB and I disabled the computer wifi.
The scanner is detected by "scanimage -L" and I can scan with "scanimage --
format=tiff > image.tiff".
I can scan with 75 (default), 150, 300 and 600dpi resolutions. 1200dpi (which 
is not proposed by the scanner screen) takes about five minutes and output a 
corrupted image.
When I type "scanimage --format=tiff --batch --button-controlled=yes " it 
says :
Scanning -1 pages, incrementing by 1, numbering from 1
Scanning page 1
So I start the scan from the scanner (I set the output location to Local (USB) 
and press the COLOR button), the scanner says "Please wait..." for a while but 
scanimage does nothing.

WIFI test :
I did the wifi test again, just to make sure (truth is, in the last test, I 
typed "--resolution 300" instead "--resolution=300").
75, 150, 300 and 600dpi work fine, I don't have any errors anymore. But with 
the 600dpi resolution the scanner seems to stop and then start its engine 
several times during the scan, and the time to send the image to my computer 
is longer than when I use windows. Maybe it's possible to send the image 
during the scan.

SCANBD test :
I tried to set up scanbd with the help of the archlinux wiki (https://
wiki.archlinux.org/index.php/Scanner_Button_Daemon), but I get this 
("journalctl -u scanbd"):

sept. 23 16:31:25 some-pc systemd[1]: Started Scanner button polling 
Service.

Hi Lovro,

Your scanner wasn't fully supported by the backend version 1.0.24.
1200dpi scans don't work.

Everthing else should work with scans up to 600 dpi. Please test all
options with your favourite frontend. I prefer xsane.

If you might get problems with 1.0.24, you won't get around to install
Sane 1.0.25 from git.

The brightness of the scan result depends on the scan settings. Please
try the sliders in xsane and watch the results in the preview window.

Hope this helps.

Cheers,
Rolf

Hi,
Just a comment: This is already fixed more than a year ago, so if you
need this then you can install the source, or wait for 1.0.25 to be
released and be available in your distribution.
Changelog entry:

2014-05-08 Rolf Bensch 
* backend/pixma_mp150.c: fix MG7100 image data post processing @ high
  resolutions > 600dpi.
* doc/descriptions/pixma.desc, doc/sane-pixma.man: Canon Pixma MG7100
  Series scanner is working, reported by Gert Cauwenberg.
* backend/pixma.h, doc/descriptions/pixma.desc: Pixma backend
version 0.17.8

/../
Regards,
Gernot Hassenpflug
