Canon MX870 won't scan with Adobe XI Pro
I just got a MacBook Pro with OS X Yosemite 10.10.2 and can't get my printer (a Canon MX870) to scan a document with Adobe XI Pro. I used to scan documents all the time with the MacBook Pro I had and Adobe IX. I can't for the life of me see where the problem is. I select Create a PDF from Scanner and nothing happens. No error message. Nothing. The printer otherwise works fine, as does Adobe, which I use to mark up PDFs. Any suggestions?
