After you wrote the same mail to me on 2000-09-24 I had answered this. Didn't
you get the answer or didn't my solution work? Here is a copy of my answer:
br-x is the bottom right x position. So this value is probably to big. The
problem is that scanimage first calculates its x (width) value by doing br-x
- tl-x.
Then it gets the new value for top right x tl-x (-l 5) but doesn't
recalculate it's width. So the old width is used (full scan area) which is
too wide.

Add a width parameter (-x), e.g.:
scanimage -d mustek:/dev/scanner -l 5 -x 210.9 --contrast 0 --resolution
201 --mode Gray >/tmp/out2.pnm
Bye,
Henning
