I’ve got the new ScanSnap Manager that works with Catalina installed. When I start from the ScanSnap Manager and send to DEVONthink it works fine. I set the profile to the DEVONthink one and select duplex scan from the menu.
However if I start a scan from DEVONthink using the ScanSnap button or from Import > Scan from ScanSnap it always does a simplex scan and only scans one side of the page. Is there a way to get DEVONthink to do a duplex scan from the button? Minor issue since the other way works fine, but I like hitting the button instead.
Scanner: ScanSnap S1300
ScanSnap Manager: Version 7.0 L20
DEVONthink: 3.5.2
macOS: 10.15.6
