Acrobat - OCR - This page contains renderable text.

I am unable to perform OCR on a PDF. When the operation is attempted, the following message is received:

"Acrobat could not perform recognition (OCR) on this page because:

This page contains renderable text."

The page is unable to have OCR performed. The only way around this is to Sanitize the document and then run the recognition or print the document as an Adobe PDF and re-run the OCR.

Using Adobe Acrobat XI 11.0.20

Has anyone found a fix for this issue?
