@tigerjack89 -- There are a couple of issues. The main one is that there is a gray line down the edge of some of the pages which is causing your trouble. There are two ways around this. One is to use -evl 1 (erase vertical lines), or check the "erase vertical lines" checkbox. The other is to set the margins to a value like 0.05 inches (-m .05) so that k2pdfopt ignores lines on the very edge of the source pages.

The other issue, at least for the sample you sent to me, is that a dpi of 400 is way too high because the scanned images on each page are only at ~72 dpi. Because you are specifying your device width and height in cm, your output dpi is having no effect on the output text size, so specifying 400 is only making the output file size (in bytes) larger than necessary without improving your quality. I'd use -odpi 150. If you want the output text larger, then use -ds 1.5 or -ds 2.0, for example. You should see no difference in the quality, and your output file will be much smaller and the conversion will be much faster.
