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 f?r Ihre Anfrage zur Scanfunktion mir Ihrem PIXMA MX375. Eine M?glichkeit der Scan to PC Funktion zu nutzen besteht mit diesem Ger?t aus softwaretechnischen Gr?nden nicht. Wir bitten Sie, uns nachzusehen, dass wir Ihnen keine anderen Informationen geben k?nnen 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 f?r Sie sind. F?r weitere Fragen stehen wir Ihnen jederzeit gern zur Verf?gung.
