A common occurance with automated instruments is that the specimen head has
"crashed" into the pressure plates during operation.  One must inspect the
pressure plates for imperfections (nicks and dings).  These will cause
"stress" in the blade and will always produce the characteristic Venetian
Blinds.  This is true of both the front and/or the rear pressure plate.
The front one is easily removable for cleaning and is therefore subject to
damage along the front edge.  If these imperfections at the point of
contact exist the only solution is replacement of the damaged plate(s).
