I just recently discovered NAPS2 (and really love it. I am using it instead of PaperPort!!!!) and am trying the 3 beta 1. It says it can OCR, but nothing happens when I highlight the scanned image and click on the OCR button. Is there another way to do it? Thanks.

Hello, i spent quite some time today trying to make NAPS2 to scan properly. And seems i cannot do anything about that. We are using canon scanner called Flatbed scanner unit 201. When i start NAPS2 (i tried 5 different versions, and latest which is beta 3,01) Size setings doesnt work f.x. if i set it to scan it A3 it scans only area that looks somewhere like A4, and all the rest area is Black. Even the Whole glass is covered it is stil only fragment of what we want to scan. Only DPI, Brightness and Contrast setings seems to work fine, where it doesnt even change from colour to grayscale or Black&white. Anyway good work needs to be improved but the interface its nice and looks easy to use !

I'm having issues with it running out of memory while scanning in color at 600 dpi.

Right now it runs in 32-bit mode, maybe switching to 64 would eliminate that?

For the memory issue, after a bit of analysis my best guess is that your scanner isn't providing a valid image of the page for some reason, not that you're actually bumping up against memory limits. Unfortunately, if this is the case, there's not much that can be done other than trying different settings.

If you have OCR enabled, it should take effect automatically when you save a PDF, and you should be able to search/highlight/copy text in the PDF.
