[sane-devel] Canon Pixma MP230

[Rolf Bensch]

Hi Marc,

Please test all scan options with all resolutions first. I assume that
SANE can only support up to 600 dpi.

Also test button support. Press any button and send a status request to
the scanner: 'scanimage -A'. The response should contain something like
this:

  Buttons:
    --button-update
        Update button state
    --button-1 <int> [0] [read-only]
        Button 1
    --button-2 <int> [1] [read-only]
        Button 2
    --original <int> [0] [read-only]
        Type of original to scan
    --target <int> [5] [read-only]
        Target operation type
    --scan-resolution <int> [0] [read-only]
        Scan resolution

If no data will be shown, please enable debut output with: 'export
SANE_DEBUG_PIXMA=11'. Then look for these lines:

  Buttons:
    --button-update
        Update button state
[pixma] INTR T=1.663 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]

(Shown data is from my scanner and may be different from your scanner's
data.)

The received data is processed in function handle_interrupt(). For
details please read the comments in the code and 'man sane-pixma'. If
you'll have problems with this, you can also send the responses for all
buttons to the mailing list. Then I can create the patch.

Then you can send the diff file to the mailing list. I'll commit it to
SANE git.

Cheers,
Rolf
