I'm really beginning to like ClearScan a lot. I have to do a tremendous amount of reading and it is ClearScan makes things easier to read. What I would like to know is if it is possible to run ClearScan on a .pdf that has been previously OCRed by either an earlier version of Acrobat? At the moment, when I try to do so I get an error message that states,

"This page contains renderable text."

How, if at all, can I run ClearScan on these documents? Thanks for the help

My Product Information:
Acrobat Pro 9.1, Windows

Jlamarca,
Any page in a PDF that contains "renderable text" cannot be processed by Acrobats OCR engine.

Any PDF that has an OCR layer can have the OCR removed via the Examine Document feature.
This feature became available with Acrobat 8 (certainly 8.1.0 or better) and is available in Acrobat 9.x Professional/Extended.

Be well...

Thanks, daka630. While I could remove the underlying OCR layer, the document still contained "renderable text."

I did, however, find out that I could then use the TouchUp tool, select all text on a page (it was fastest to use Ctlr-A > Ctrl-C > delete. At that point, I could then run ClearScan which then made the text more readable.FYI, I'm running Acrobat Pro ver 9.

Thanks again for your response.
