[sane-devel] How can I help with Canon Maxify MB2000 series testing?

[Rolf Bensch]

Hi Louis,

Please try to fix this issue. The main problem are special needed
settings in function send_scan_param() (command 0xde20) from
pixma_mp150.c. You can fetch correct settings from reference scans from
a Windows machine.

To check button support, you can use this simple test:

1. push any button

2. $ SANE_DEBUG_PIXMA=11 scanimage -A

If you scanner has button support, you should get a similar response:

[...]
  Buttons:
    --button-update
        Update button state
[pixma] INTR T=1.165 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
    --scan-resolution <int> [0] [read-only]
        Scan resolution
[...]

Important are existing lines starting with [pixma]. With this info it's
simple to enable button support.

Hope this helps.

Cheers,
Rolf
