 Today I picked up a new fuser and replaced it, and now it works.
 However, there's a vertical line of what I can perhaps best describe as
 fog on every page. 
 
I just got over a similar problem with my LJ5MP,  running down the left side
of the page.  :-(
  Last time I had something of the sort, replacing the
toner cartridge (which
 includes a roller of some sort) fixed it. 
The cartridge in my case includes the drum (I understand that's not always the
case) but it's a rubber wiper in there that's the problem.  Replacing it was
also the solution in my case.
  I slid the door over the roller open and the fog is
visible on the roller
 too.  Perhaps interestingly, this fog was not present on the first few
 pages printed (which were test pages); it showed up while I was
 printing "real data". 
Yep,  the toner that's deposited on the drum is supposed to be removed by that
rubber wiper,  which apparently has a bad spot on it.
  Is this something that can be fixed, or will I just
have to put up with
 it until I change toner cartridges? 
How ambitious do you want to get?  :-) I may someday have a go at tackling
that cartridge I removed,  if I can find a convenient source for the part,
but I'm in no particular hurry to do so at this point.
  Also, the thing is giving me a lot of paper jams with
the page stuck in
 the paper path after the fuser - sometimes they register as internal
 jams, sometimes as output jams.  It's not consistent, but frequent
 enough to be annoying.  Any ideas what could be causing that? 
Is there some rubber roller in that portion of the paper path?  If so,  that's
probably the culprit there,  too.
I just got into the yahoo "printer support" group,  and am finding it useful.
