Newer HP laserjets probably do have a shorter fuser life than some of
the older printers, but 24,000 pages is woefully short of what should
be expected from a LJ1200 or LJ1300 engine. For instance the
LJ1010/1012/1015/1020/1022 engines have an anticipated fuser life of
at least 60,000 pages and they are entry level lasers. The 1300
should do more than that if well looked after.
It's the expected life of the fuser in particular I'm talking about which is
defined seperately somewhere in the data sheets. Can't seem to see it now
:-(.
I don't see why 'well looked after' has anything to do with a fuser. Unless
you count pulling out a sheet without releasing the rollers which is instant
death!.
Other than lack of fuser oil (as described below) it may simply be that the
very rapid heating and cooling of the element will eventually cause it to
fail more quickly than the traditional fuser. Of course the traditional
fuser had problems with the ptfe film which covered the fuser, however
replacing the fuser was usually a rare event.
The newest HP fusers do not use fuser oil, this included the LJ1300.
Well, if it doesn't, then it's the single exception and I don't see why it
shouldn't. Replacement of the fuser film is not a recognised repair by HP so
it's not described in any HP manual, however the same fuser film fits a
whole series of these lasers and if you find someone selling it you should
find him selling with it fuser oil (actually it's white grease) and I can
definitely state that at least two (probably all of the fusers in this
range) _do_ use fuser grease. It's probably that if you don't clean and
replace this, the replaced fuser film _will_ have a shorter life, so maybe
this is why some people say here that fuser film replacements don't last as
well?.
The replacement part for this particular model cost about £80 in the uk,
which is a substatial part of the second hand value of this now discontinued
printer. Aftermarket fusers are likely to just have the film replaced (it's
a simple job when you've got the fuser unit out). So who knows in this case?
