[sane-devel] Canon Pixma MX925

[Hans Pirnay]

Hi Rolf,

I will get back to you with the scanning tests as soon as I can. For now, I
just tried the button tests on a PIXMA MX895 (over wifi), and I'm not quite
sure if I'm doing what you asked me to, so here's what I did:

$ export SANE_DEBUG_PIXMA=11
$ scanimage -A

press any button

$ scanimage -A

no result. However, if I actually listen for buttons I get this:

$ scanimage -d pixma:MX890_192.168.2.102 --button-controlled=yes > output
[sanei_debug] Setting debug level of pixma to 11.

... here I quit with CTRL-C

The first button is "Color", the second "Black". After I hit these buttons
the printer sits there for a while, seemingly not doing anything; no
scanning noise/movements, and the scanner's screen shows "Processing.
Please wait momentarily".

Is this what you are looking for?

best
Hans
