OCR does a remarkable job converting page images into text, providing your image is of optimal quality. Nothing will save you when the original pages were of dismal quality; you’re going to have lots of errors, and it may not be worth attempting to create a text version from them.
But more often, I find that most pages are good, and the OCR result is therefore acceptable, with just a few pages where the entire page is corrupted. This is usually because the original scan skewed the page beyond the limits of the OCR software. In such a case, you may be able to rescue the text by de-skewing the image for a page and re-doing the OCR for that page.
