Many thanks for your report.

You can install xsane. It's an easy to use gui.

Please check and report all scan resolutions up to 2400 dpi.

And please check and report button support.

How to check button support:
(1) Press any button.
(2) Check output from 'scanimage -A'.
(3) Repeat (1) and (2) with all other buttons.

The response from scanimage should contain useful data like this:

  Buttons:
    --button-update
        Update button state
    --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

If you don't get any data here, enable debug output with 'export
SANE_DEBUG_PIXMA=11'. Then the response should look like this:

  Buttons:
    --button-update
        Update button state
[pixma] INTR T=1.654 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

Please provide the lines starting with [pixma] with the pressed button.

Many thanks for your help.

Cheers,
Rolf
