I would treat a big white top margin with full extents, left and right as normal, but to have some leftover white on the right may indicate there are scanning artifacts on the page interferring with the internal cropping function that removes as much of the white space as possible (and retain the same aspect ratio). You could try entering Size H: and V: as different from 583 and 753 to help squeeze the white out!
In the end, if the scanned page in portrait mode is not in the same aspect ratio as the 505 screen, then it may be NORMAL to have a small amount of white on top and to the right, so nothing to fret about!
You may greatly benefit from the 'unpaper' option. If you click the word 'unpaper' on the GUI option screen, your browser will be directed to a website detailing the benefits of using 'unpaper'. It basically tries to counteract the effects of "bad" scanning errors (dark areas on the side, skewed pages, etc).
IT IS VERY TIME CONSUMING THOUGH! Several minutes per page!
To activate it, just place parameters (like '-v' for now) in the input box beside the word 'unpaper' on the GUI option screen.
You should only test it on a specific range of pages numbers i.e. 1 to 5 (which may take half an hour!)
Then refine the unpaper input paraemters so as to only perform the operations you need. I've only done a few tests and know it can automatically deskew (straighten) pages, but have not done this for an entire book, let alone a 300 page pdf! (Let's see, 5 min per page x 300 page pdf = 1500 min / 60 min per hour => 25 hours or a day!)
