I should have put more information about the patch for others:
It was only on the www.usa.canon.com website. It may not be on other countries websites which is why I missed it.
It says:
This patch resolves an issue that prevents scanning over a network or with a USB connection after upgrading Windows to a newer version. If you cannot scan over a network or with a USB connection, install this patch. If installing (or reinstalling) the MF driver, be sure to first restart (not shut down) your PC after driver installation is complete, and then install this patch.
