One in which when the photocopier's paper jam light goes, the 
operator SHOULD open the cover and remove any crumpled
pieces of paper, which should resolve the problem.

These are very distinct senses of the word - one indicating the

of a particular result.  Only for the former does any kind of "normative"
semantic make sense.
