PDF Conversion doesn't see hidden text

I've searched for what might be a really simple answer but couldn't find anything, so here goes:

I have a PDF that was created by scanning and OCR using Prime Recognition OCR software. When I try to convert it to ePub, all I get are the scanned images of the text, not text from the hidden text. I know the OCR worked because I can search the PDF, and I can copy text from it.

Is there a setting or preference that tells Calibre to use the hidden text for conversion rather than the image of the text?

OK, but now I'm really confused ... I have used Calibre to convert PDF documents that I've downloaded from the web to ePub with no problems. They look just like ePub books I've purchased. I assumed those PDF files were created from scans of the original, but perhaps I'm missing something here.

How does one get the text from scanned document into ePub format?

Reading text under images in PDF is not supported by the PDF engine calibre uses. PDFs where the text is not an image but the actal text is supported.
