Hi Hans,<br>
<br>
Many thanks reporting ADF duplex on MX920.<br>
<br>
Please try to scan a color image with *all* resolutions from 75 dpi up<br>
to 2400 dpi and report if *all* are OK. To reduce scan time you can scan<br>
a small area. If you might see problems you can send the pnm files<br>
directly to my email address. The ml rejects large emails.<br>
<br>
Please also check button support on the command line with 'export<br>
SANE_DEBUG_PIXMA=11' and 'scanimage -A':<br>
- 'export SANE_DEBUG_PIXMA=11'<br>
- press one button<br>
- check the output from 'scanimage -A'<br>
- press the next button and again check the output from 'scanimage -A'<br>
- repeat until all buttons have been tested<br>
<br>
I'm interested in the debug output from each button which looks similar<br>
to this:<br>
<br>
Buttons:<br>
--button-update<br>
Update button state<br>
[pixma] INTR T=1.656 len=32<br>
[pixma] 00000000:00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00<br>
[pixma] 00000010:00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00<br>
[pixma]<br>
--button-1 <int> [1] [read-only]<br>
Button 1<br>
--button-2 <int> [0] [read-only]<br>
Button 2<br>
--original <int> [0] [read-only]<br>
Type of original to scan<br>
--target <int> [2] [read-only]<br>
Target operation type<br>
<br>
Many thanks for your help.<br>
<br>
Cheers,<br>
Rolf<br>
