how do I install a scanner?

I have an Ambir ImageScan Pro 820ix and can't get it connected. How do I go about it or do I need a different kind. 

Good evening,

Please see the following link for new scanner install. If the scanner is not compatible for direct scan, you may scan to your designated M3 folder as a PDF and attach images using the "Browse Pre Selected" option.
