Hola Ma. Renee
Mirando en sitio de Canon no es posible encontrar ningún driver para Windows 7 64 Bits. Lo único disponible es para 32Bits. Hay que contactar ellos para chequear cuando va estar disponible el driver para Windows 7 en 64 Bits
Canon is working with Microsoft to include updated device drivers for our products with the Microsoft Windows 7 and Microsoft Windows Vista operating systems.
Many Canon drivers will ship with the Microsoft Windows 7 and Microsoft Windows Vista operating systems.
Canon is working to develop updated drivers for our products so that all of our current and many older products will work with Microsoft Windows 7 and Microsoft Windows Vista moving forward.
