No list of programs to scan from

I believe Canon provides a software tool with the drivers that come with printer called MP Toolbox. This software will have options for defining those 'scan to' destinations.
You can get the latest version for your Canon printer at the following link: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=334&modelid=9527


Please be sure to select the correct operating system to get the drivers/software for your setup.
