We've never seen dim edges except as an early sign of the cartridge giving
out on our LaserJets, and most of our stuff has substantial and fairly
consistent margins.  Hm, except for our header pages, which do print a
noticeable amount of black across the full width -- maybe that does it.
(We use the checkerboard pattern of the DEL character in the LaserJet's
built-in font for header banners, and it gives us another useful bonus in
that they usually show cartridge-is-dying fading before text pages do.)

There does seem to be a "breaking in" phenomenon in which cartridges give
relatively light print for the first few hundred pages.  We observe this
quite consistently.  We've never bothered with the print-density adjustment,
which in our experience has such negligible effects that it's not worth
the effort.
