Came home with a dumpster-find Laserjet 4 (with jetdirect board) yesterday.
Self-tests OK but prints with some minor repetitive ghosting on the pages
(it has almost a million pages on the clock).
There's some baked-on toner on the fuser roller which might[1] (most
probably!?) be the culprit, but gentle cleaning doesn't seem to get rid of
it; question is, how aggressive can I be with it? I don't know if the
blue-gray color is just a thin coating of something magical, or if it's a
hunk of solid metal which can be scrubbed.
Certainly on the CX and SX engines it _is_ a thin coating, I've always
assemed to be PTFE. It can tear very easily, when you get black streaks
down the printout.
How much doe a eeplacement roller cost? Do the PrinterWorks have it?
I wonder if heating it (w.g. with a hot air paintstripper) would soften
the toner and make it easier to chift?
