I have a Canon MX922 and I want to update this software so I can scan photos and get them on a disk!

Click on this link to the Canon support webbsite, make sure the operating selector

is set to your operating system,

Click through Drivers, Software, Firmware and Utilities to see what downloads are available to you.

When downloaded you will then need to then install them.
