Canon MP530 – change default scan buttons actions

How to change the default scan button / buttons actions.
Windows XP (maybe others)

1. control panel -> scanners and camears
2. select the WIACanon MP530 driver
3. right click properties -> events
4. change events action to what you require

Intuitive after you know where to look… took me a bit of time, so hope this helps others that want to change the default actions.
