Thanks for the reply! In doing my research, I saw you posting a lot and my inclination was to just send a message to you, so I am glad your replied. 🙂
So my problem (if you want to call it that) doesn't have anything to do with the scanner. It feeds pages through just fine and the scans look good. Let me try to explain with an example.
Source: a 10-page document printed on 8.5x11 white paper that has printed text on one side of all sheets and the second side of some. Some of the pages also have hand-written notes written in the margins. One last wrinkle is that a few of the pages are oriented in landscape (graphs with images and text).
I know there is an option for the scanner to either scan simplex or duplex, so I'd have it in duplex. An additional setting allows the software to ignore blank pages, which I also have enabled. There's also the option for auto rotation, which I'd have enabled, too.
If the scanner was flawless in matching my expectations, the PDF scan would be perfect: all blank pages ignored and landscape sheets oriented properly in the scan. However, the reality is that sometimes adjustments are required. In this case, maybe a few of the blank pages have stray marks that the scanner interprets as a non-blank page and some of the landscape images aren't recognized and correctly properly. I should note that I do NOT expect the software to be flawless in this regard and fully expect some manual adjustments like this after any scan.
So here's my "problem": On a Mac, once the PDF shows up in the Evernote client, the only way that I know of to make adjustments (delete the blank pages and rotate a few pages) is to open the PDF in Preview, make the changes, then save the file. I used to do this, and it works. However, when I was able to scan multiple-pages into a single note in JPG format, I could accomplish those changes by editing the note directly in the Evernote client. So I am talking about an extra step (opening and processing in Preview) that takes me and my computer extra time. Poor me, right? LOL I just got used to the convenience of the JPG scans. But you make excellent points about the differences between JPG and PDF.
I really appreciate any further comments/ideas you might have! I am really not upset by any of this, just trying to re-establish a workflow that meets my needs. Also, I like talking about these things with fellow enthusiasts. And thank you for the tip on the new 64-bit version of the ScanSnap Manager, which I will hold off on for now, as you suggested.
