[sane-devel] Canon Pixma MX925

[Rolf Bensch]

Hi Hans,

Many thanks reporting ADF duplex on MX920.

Please try to scan a color image with *all* resolutions from 75 dpi up
to 2400 dpi and report if *all* are OK. To reduce scan time you can scan
a small area. If you might see problems you can send the pnm files
directly to my email address. The ml rejects large emails.

Please also check button support on the command line with 'export
SANE_DEBUG_PIXMA=11' and 'scanimage -A':
- 'export SANE_DEBUG_PIXMA=11'
- press one button
- check the output from 'scanimage -A'
- press the next button and again check the output from 'scanimage -A'
- repeat until all buttons have been tested

I'm interested in the debug output from each button which looks similar
to this:

  Buttons:
    --button-update
        Update button state
[pixma] INTR T=1.656 len=32
[pixma]  00000000:00 20 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]  00000010:00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]
    --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

Many thanks for your help.

Cheers,
Rolf
