Scanning from Quick Scan Button on Scanner - File Doesnt Open

This will probably not be what you want to hear: 

Acrobat cannot scan
Acrobat cannot scan, at least not by itself. There is NO scanning function within Acrobat. Rather, Acrobat uses other software to scan. On a PC, this is done via a "linking" software called Twain. On the Mac, Twain is not allowed for the same reasons they kicked off Flash (too many potential virus issues). 

I encourage you to continue scanning with your scanner’s software, save your scans in the TIF format, and leave the files on your desktop (or wherever convenient). If you save the files as TIF images, Acrobat will automatically OCR them; there's nothing else you have to do. If you drag more than one file onto the Acrobat icon, Acrobat will ask you if you want all of these files merged into one document or to remain separate. (If you save in any other format, the auto OCR dynamic will not happen, and you'll need to add to your workload by adding an OCR step to your activities.)
 
Some extra tips and bits of information: A full-page, 300 ppi, 8-bit TIF file will be about 8 MB. (16-bit will be about 16 MB); once they are processed into a PDF, they will drop down to about 80-150 kb depending on the amount of content in the document, so do not worry about the initial size. Assuming that you've done a pre-scan to set the Levels settings to get a clean image and you're doing a stack of pages from the same source, there's no need to do subsequent pre-scans. The first scan will be document.tif. The 2nd document will be document (2).tif, the third will be document (3).tif., etc. When you process those in Acrobat, the first scanned page will end at the end of the PDF as the last page. You can either fix this in the "Organize Pages" or, before processing in Acrobat, change the name in the Finder for document.tif to document (1).tif. (There's no way around this because it is up to Finder or Explorer to name it, not the scanning software.

Issue: Can’t scan multiple pages
There are two dynamics when working with computers: getting the job done the way it's supposed to work and getting the job done.

I'm on a Mac, and I've seen this issue in the forums for years. For whatever reason, it doesn't seem to be solved. I do not work for Adobe, so I cannot say what the issue is nor why these issues remain. 

What I recommend for you to "get the job done" is to do the following
1) use the software that came with your scanner.
2) scan the stack of papers and have them saved as TIF* documents in a convenient location.
3) Once the scan is complete, select them all and open File (menu) -> Create -> Combine Files into a Single PDF.


This will ask if you want all of the files separate or combined into one files. Then, It will convert the images into a PDF .

* If you save the files into other formats (e.g., jpg or png), Acrobat will not automatically OCR them. However, if you save them in TIF format, it will.

I have experience (with FujiSCAN) that multi-sheet feeder software can convert them into PDF, but their OCR is not very good, and the file sizes are very large. However, you can take the final PDF from their software and run them through Acrobat for much better results. I suggest you test to make sure before you commit to a long process.

Speaking of long processes, Acrobat does not play nicely with other applications. Acrobat will prevent you from doing anything else during the OCR process, even reading emails. After each page is processed, it will jump in front of what you're doing and let you know a page was completed. For very lengthy documents, or processing multiple documents, I found it best to have lunch breaks, coffee breaks, whatever.

Good luck.
