"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."

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.
