I guess it will be similar to my canon model (MP620). I enter the 'My printer' program - a shortcut was probably put on your desktop when you installed the printer, but if you can't see it should be able to double-click the printer icon in the bottom right of the screen to start it. I then select 'printer settings; and then 'maintenance', and head alignment is an option listed. Hopefully your route is fairly similar - once you are in the control program it should be fairly easy to find, so have a look around. Good luck.
