I've been told that the reason you're seeing this, is that HP scanners use
two interpolated sources of scan data, to double the resolution (this could
be wrong, but it makes sense...).
If this is the case, then you need to read both data streams, and
interpolate the pixels - otherwise, you'll get a picture which looks almost
correct - but not quite...
