Replacing Text Content

[PHK]

I have just bought a new scanner that is WIA only. It is a generation smarter than my previous TWAIN scanner so it does things like automatically recognizing page sizes, duplex (deleting blank backs), and color vs. b/w. And it OCRs, too. But I cannot use the PDF-XCE app to control what happens in the scanning process; rather, I must use the proprietary software that came with the scanner. This actually doesn't bother me too much as I am comfortable operating the scan from the on-device menu that places all scanned pages in an intermediate folder from which I can distribute the pages to their appropriate folders and files which is not vastly different from the way I was handling scanned documents anyway.

But that raises a concern. For instance, I have no idea how its OCR compares to PDF-XCE's qualitatively. It's early days, but I have not yet detected any problems. However, I am thinking I might want to run the PDF-XCE's OCR software on some (if not all) documents for consistency and quality purposes. But I do not want to create duplicative content.

Therefore, my question is: can I (or should I) purge text content produced by the proprietary software OCR and then run the PDF-XCE OCR?

P. S. Upon further investigation, it seems the app used is ABBYY FineReader. How does that compare to PDF-XCE's OCR engine?
