How to clean Fuser Roller on LN03 Laser Printer?

I have an AST TurboLaser/PS (also known as an Dec LN03, a Brother, etc, etc)

When I bought it someone had let a ring of melted toner collect on the fuser
roller until it had burnt through the coating and ruined the roller.

So I replaced it and ran a few thousand copies through the printer. Now I
notice that the roller is beginning to collect a bit of toner again. Just
how does someone clean that roller without pulling the coating off? I tried
the usual wiping with a paper towel and that removed some of it but there is
still a hint of it left and a few more copies begins to let it accumulate
again.

thanks

Try with a wooden stick when the fuser roller is HOT. Don't use
something with sharp edges ... (I know this sounds not very
intelligent but i don't know another easy way to clean acumulated
toner from the fuser roller)

Try wiping the roller with a Kleenex soaked in lighter fluid when
it is COLD. If you get tired of wiping, as this is a gentle
cleaner, try nail polish remover (acetone). Test it first on the
edge of the roller, as it may damage the teflon coating.

I wonder if your fuser is running too hot as well?

I would bet the "picker fingers" or "separation claws" are in need of
replacing. They are the claw type pieces that ride on the roller and
prevent paper from sticking to the roller. The end that rides on the roller
will build up a coating of toner and crud and will wear a groove thru the
teflon coating of the roller. Once the teflon coating is gone, toner builds
up in the groove and shows up on each page as a faint line.

I'm not quite up on fusers yet, but this is the purpose of the fuser
blade--to clean excess toner from the roller. If it's a little warped, it
will not clean the part of the fuser roller that is under the warped
area. Even if it's not warped, it may still need cleaning.

There is also a drum cleaner blade which cleans excess toner off of the
drum between pages. On a regular copier, this would show as streaks or
even a double image that only shows when you print more than one page at
a time.

Sorry I missed the original message Sam, but the best way to
clean a fuser is to use a very light coat of silicon oil.
This is used on the heated fuser as well as the pressure
roller.

The function of the fuser is to bind the ink to the paper
thru heat and pressure it should not accumulate any ink
during normal use, it doesn't remove or collect toner
normally, unless the surface is dirty or deteriorated. The
teflon on the main fuser should be slightly shiny much like
the surface on a "Silverstone" frying pan.

The item you were thinking of is the drum wiper blade which
is a part of the drum assembly and is usually responsible
for streaks / smudges that persist on the photo drum's
surface and make perminent smudges on copies.

I learned of the silicon oil treatment from a 3M service
rep. I was using alcohol in the copiers I seviced up to that
time. He showed me the way to do it by wipeing the fuser
components with a non linty rag with a little oil on it
until the rollers were copletely clean then drying them with
another cloth. The job naturally was done with the rollers
fully dis-assembled but in his case could be done with
minimum removal just so the rollers could be turned and
reached without touching the drum assembly, the oil would
kill it.
