If the answer is true, then with the device powered and with a network connection, visit System Preferences : Printers & Scanners, and right-click on the printer entry, and choose Reset printing system… . This will take you to the re-add device dialog, where you would choose AirPrint instead of any Canon selection. Then, re-add the device. Print something. There should also be something on Printes & Scanners panel to select your scanner too.
