Hi Ronald,
Please test 'scanimage -A' instead of 'scanimage --resolution 300
--button-controlled'. Source and action should fill the response fields
'original' and 'target', e.g.
$ SANE_DEBUG_PIXMA=11 sanimage -A > test
...
--button-update
Update button state
[pixma] INTR T=44.622 len=64
[pixma] 00000000:*/11 01/* 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> [17] [read-only]
Type of original to scan
--target <int> [1] [read-only]
Target operation type
--scan-resolution <int> [0] [read-only]
Scan resolution
...
$
Please check which buttons trigger --button-1 and --button-2. In some
frontends (e.g. scanimage, xsane) --button-1 is used as 'SCAN' or
'COLOR' button and --button-2 is used as 'GRAY' or 'END' button. If the
assignment is not clear, I would like to patch this issue to your needs.
Another great tool for button controlled scanning is scanbd
(http://sourceforge.net/projects/scanbd/). scanbd is also supported via
the Sane mailing list.
Cheers,
Rolf
