By default, it will suppress all error messages. You can go and look for OCR suspects after the 1st OCR. But it's pretty good. I also have OmniPage for OCR and it doesn't even come close. That one throws out error messages nonstop. Acrobat will add a text layer to the existing PDF. If there is something like an image, you can just copy and paste it. It doesn't look like it retains formatting. Just a plain text layer underneath.
You can even have it down sample the original to reduce the file size of the output file.
