There seems to be many assumptions in that reply, but I didn't supply every detail for you either. The fact remains that my MR+ Pro works perfectly now that the PDF files have been reduced in size.

I am scanning paperbacks using a Fujitsu Scansnap s1500 at 300dpi and the page size is about 4.04x6.85 with small variances from book to book. Using a lower resolution affects the quality of the reduced version without gaining any appreciable reduction in file size which is why it may seem high. I'm reading these on a Samsung Galaxy S3, not a tablet. BTW the resolution is 306ppi on the phone, with a screen size of of 720x1280 or 2.35 X 4.18 inches.

I was kind of excited to read your reply as I hadn't tried using the readers to reduce the file via printing. Too fixated on the "Optimize" option from Adobe I guess. So I did some experimenting.

A typical scan is anywhere from say 15MB to an average of 50MB but can be higher. Your idea of using the print to file sounded interesting so I compressed a 31MB scan using every variation I could in the output to reduce the size. That optimizer I'm using now can get it down to 7.9MB. using Adobe Reader or Foxit Reader the size goes up instead of down. In fact the best result I was able to obtain was 71MB after sacrificing some quality. I had originally started out with K2pdfopt as it allows me to customize the output size, but this also results in a larger file than the original(but only slightly so. Incidentally there is no margin to remove from the scan I'm testing with. The printer used almost all available space on the physical page LOL.

If you have any wisdom to impart that could get me a better result than 25% of the original I'd love to hear it. I have about 1000 books that I'm converting.

Thanks!
