I kept getting an "Acrobat could not perform recognition (OCR) because: Unable to process the page because the Paper Capture recognition service experienced an error. (15000)" when I tried to "Recognize text using OCR" using Acrobat 7.0 PaperConvert OCR command on my Powerbook G4. I tried a couple of languages (the document was in German) and several choices of PDF output style without success. After reading other posts in this forum, I decided to export all four pages as images. I opened and resaved them as TIFF (LZW compressed) files in Photoshop, then reopened the TIFFs in Acrobat. The OCR translation worked right away in German. I hope this helps others - including those having scan-to-OCR problems. Stick with TIFF if possible.
