I have two Canon multi-function printers (MX880 and MG7100). I recently got a new computer, and for the life of me can't find where to download the Navigator scanning software from the Canon website. I spent an hour at their site, and the only scanning software they directed me to was for the MX892, which doesn't work on my machine. Please help. Or, if there's a better scanning solution to Canon's, please let me know.
