Welcome to The Canon Forums, and thank you for your inquiry!
We appreciate your participation, however we need to let you know the Canon Forum is hosted and moderated within the United States by Canon USA. We are only able to provide support for Canon products manufactured for and used within the US market.
Support for Canon UK can be found on http://www.canon.co.uk/support/
Feel free to discuss Canon products sold outside of the United States, but please be aware that you will not receive support directly from Canon USA.
That being said, while we don't support the MX430, I did find this information about the MX432 that is sold here in the US, and I can't imagine they're that different. CLICK HERE
