Acrobat won't print multiple pages--it asks if I want to and, after the first page it asks if I'm done or want to scan page 2. I select it and click ok, and the message goes away, it doesn't recognize the next page on the scanner, and the program locks up; I have to end task in Task Manager. Removed and reinstalled the printer, uninstalled and added back Acrobat, and no joy. Also can't change any of the settings for the scanner--all options are greyed out. Any help?
