I want to use the OCR part of the navigator program with the automatic document feeder. I did it once before, but now I can't figure out how.
The page created for this product offers different guides and tutorials on how to use the printer and available software and components. I recommend that you download these manuals to see how to work with the ADF and OCR feature. Personally, I would recommend ABBYY FineReader for any of the OCR operations because it offers powerful features to recognize text and save it for other formats.
