the message "converting scanned page to searchable image" shows when i am paging

Hi, I found the solution from an old thread which solved my problem.

* Edit > Preferences... > Reading
* Reading Order: "Use reading order in raw print stream".
* Page vs Document: "Only read the currently visible pages".

Hi, I have the same issue, this is really annoying when I'm trying to read PDF documents. Can someone look into this more deeply?

I still have the same issue as you even in the latest version of Adobe Pro DC. Doesn't happen with every document though. No clue yet how to fix that. 

I want to support this OP. I am working with Adobe Acrobat Pro DC version 20.12.20043.396433 and this problem is still happening. The program is attempting to convert every pdf file into a searchable image, even when the pdf was not scanned nor was I using edit mode. Even in reading mode the program attempts to scan every page. Please resolve this bug because it is making the program very unpleasant to use.

I have the same problem as the OP. I am running the latest continuous release version of Acrobat Pro DC (2020.009.20067) on a Mac (Mojave v 10.146). 

When I scroll through an ordinary pdf document (not a scanned document) in ordinary read mode (not edit) the above message often shows up. Usually it appears rather briefly (too briefly to read or screen shot) but it still slows down scrolling and sometimes it appears for longer. If I open View->Tools ->Edit PDF, I see the Recognize Text box is not selected, and in fact is greyed out (cannot be selected).

If I am not wrong you are in Edit PDF tool. This is happening due to a default Acrobat preference which most of the users wants. But you can change this preference following these steps:

1. Open-File in Acrobat
2. Go to Tools> "Edit PDF"
3. If it runs OCR by default, Go to RHP (window on right side of PDF)
4. There will be a link "Revert to Image" under "Scanned Document" section
5. Click on this link. It will undo OCR. And now this preference remains sticky. You need not to do these steps again and again. You can also change this preference again whenever you want, by clicking the new link available there "Convert to text".

Hope it will resolve your issue.

Thanks.
