The original pages are duplex, color, landscape.
Settings are factory default except:
Page size= 2-sided, book
Page orientation=landscape, left edge
Destination: searchable PDF
I scan 5 pages. On the scanner's preview software the images are perfect but when I open the PDF file that gets created, some of the pages have a different orientation than what appears on the scanner's preview.
And i can't get Adobe to fix the rotation on a single page.
Here's one example.
The 6th scanned page looks like this on the scanner preview.

But in the actual PDF document it's rotated 90 degrees clockwise.
Why doesn't the PDF document agree with the image displayed by the scanning software?
Thank you.
