Upgraded my computer from Windows 7 to Windows 10, have to reload all my programs. Had this issue when I first got the Windows 7 machine, long enough ago, I no longer remember the solution.
I want to select a scanner so when I need to scan something to a pdf, I can select Create > PDF from Scanner > Autodetect Color Mode, it scans. Mutliple pages, if necessary. Autodetect Color Mode is grayed out, I have to select Create > PDF from Scanner > Custom Scan. Have to make sure the correct scanner is selected, fortunately, it doesn't make me select it every time. This is a real pain when I need to scan something that's more than one page. I've tried selecting Configure Presets, it tells me, "The scanner last used by Acrobat does not support present scanning. Please select another scanner."
NONE of my scanners are apparently supported by Acrobat. I have two multifunction printers (one for everyday, ordinary printing, the other for special projects), and a dedicated scanner, a Canon CanoScan 9000F.
It shouldn't be this difficult. HOW do I establish the Canon CanoScan 9000F scanner as the default?
Acrobat X is not officially compatible with Windows 10, so problems like
that are to be expected.
Well, rats. Thank you for letting me know, at least I won't be tearing my hair out, just grumbling. Big Time.
