Your printer does show up in the "Printer and Scanner Software" link of the attached Mac Print 101 article:
I don't know if the printer was set up correctly (in System Preferences > Print & Scan). If it is not set up correctly, the article should walk you through how to do that.
If it is set up correctly, you can open System Preferences (under the Apple logo on the left side of the menu), click "Print & Scan", find your printer on the left, click it, and hopefully find a "Scan" tab on the upper right. You can click that "Scan" tab and do your scanning as directed from there.
