[sane-devel] Canon MX370 / MX430 / MX510 / MX925 - Button Support

[Matthias Peter Walther]

Hello,

Canon replyed me, that this shall be not possible.

I think we'll have to stop here? I think the hardware would be capable
of supporting buttons, but it would require a firmware change of the
device mostly. That's to heavy I fear.

Here a copy of the reply in german:

==================================
Sehr geehrter Herr Walther,

vielen Dank für Ihre Anfrage zur Scanfunktion mir Ihrem PIXMA MX375.

Eine Möglichkeit der Scan to PC Funktion zu nutzen besteht mit diesem
Gerät aus softwaretechnischen Gründen nicht.

Wir bitten Sie, uns nachzusehen, dass wir Ihnen keine anderen
Informationen geben können und hoffen, Sie schenken uns weiterhin Ihr
Vertrauen.


Vielen Dank, dass Sie den „Service & Support“ der Firma Canon
kontaktiert haben. Wir hoffen, dass unsere Informationen hilfreich für
Sie sind. Für weitere Fragen stehen wir Ihnen jederzeit gern zur Verfügung.

Mit freundlichen Grüßen
