LaserWriter 16/600PS Problem

Larry Replied: If I print a completely black page, there are some slightly
lightened vertical strips down the length of the page slightly right of
center. Also, there are "lightened blotches" about 1/4" square in various
areas of the page. These blotches may be in a repetitive pattern
corresponding to one rotation of the heat roller but I can't be sure of
that. Also, I do not know if the paper blotches line up with the dents in
the pressure roller but I suspect they might.
I did not try wiping the printed page to see if toner smudged off nor did I
attempt to wipe off any excess toner on the heat roller - it was hot at the
time I checked it.
