Digital BW, The Print

With the coming and going of this sort of thing....Could it be changes in the electrical current? I have
noticed in our 2000P, that sometimes we get a very strange pattern in plain areas that *almost* looks like
newton rings, but is not.  They come and go mysteriously and I figured it might be an electrical oddity.  We
only have surge protector not a voltage stabilizer.
