Install the minimum for the Canon Pixma MX700. Without the extra Canon software you’ll probably never use.
1. First install the Printer Driver MP Driver v1.01

With these two installed, I’m able to use my MX700 as usual. I can print and scan from all Windows applications. However I didn’t try the Fax, don’t use it anyway.
