My thought is more mechanical. Is there a noticable burr round the holes
in the pages (some manuals are prone to this) which is more likely to
catch with the pages one way up or one way round?

Have you tried scanning the back sidees with the pages rotated by $\pi$
(and then correct in software later). It may be they slip more easily
that way.
