Hi Gert,
Attached patch should fix your problem.
Please report anyway, so that I can patch SANE sources.
Cheers,
Rolf

Scanning with resolutions from 75 up to 600dpi works fine.
At 1200dpi it does scan, it does produce an image with the expected size
- but the image 'wraps around' - half of the original takes up the whole
scanwidth, and then the second half is overlayed.
At 600 dpi: http://imgur.com/69DqOt0
At 1200 dpi: http://imgur.com/KanArkn
At 2400 dpi the same effect occurs, but now 4 times. Seems like the
software somewhere expects a 600 dpi image?
On this device all settings are controlled via touch screen, so I'm not
sure what 'buttons' I should press - or how I am to run scanimage -A at
the exact moment the screen is touched. Anyway, whenever I run scanimage
-A I get the same output:

Hello,
Since yesterday I'm the owner of a Canon MG7150 all-in-one, and of
course I wanted to get it working under linux.
I'm running Ubuntu 14.04, which comes with sane backends 1.0.23. With
that version the scanner doesn't get detected - quite understandably
after looking at the source. I then installed sane backends 1.0.24,
with the scanner connected via wifi.
And ... good news!
scanimage -L detects the scanner, and using the 'simple scan'
application I was able to scan an image.
Many thanks for your report.
You can install xsane. It's an easy to use gui.
If there is anything more that I should test, let me know.
Please check and report all scan resolutions up to 2400 dpi.
And please check and report button support.
How to check button support:
(1) Press any button.
(2) Check output from 'scanimage -A'.
(3) Repeat (1) and (2) with all other buttons.
The response from scanimage should contain useful data like this:
Buttons:
--button-update
Update button state
--button-1 int [1] [read-only]
Button 1
--button-2 int [0] [read-only]
Button 2
--original int [0] [read-only]
Type of original to scan
--target int [2] [read-only]
Target operation type
--scan-resolution int [0] [read-only]
Scan resolution
If you don't get any data here, enable debug output with 'export
SANE_DEBUG_PIXMA=11'. Then the response should look like this:
Buttons:
--button-update
Update button state

Button 2
--original int [0] [read-only]
Type of original to scan
--target int [2] [read-only]
Target operation type
--scan-resolution int [0] [read-only]
Scan resolution
Please provide the lines starting with [pixma] with the pressed button.
Many thanks for your help.
Cheers,
Rolf
