Did I understand correct, that device scans perfectly well if the whole 
possible width is selected, but otherwise some combinations of 
left/right margins cause problems?

What I would do (and actually do in my backend in a similar situation) 
is to request a full width and perform image clipping purely in software.

When I came to such a decision, initially I was concerned about 
performance degradation in comparison to hardware image clipping, but in 
reality the difference is hard to notice.
