When I usta repair Xerox machines, I used trichloroethane to get rid of it.
Do NOT put trichlor on hot metal (such as a fuser), or else you'll end up
with phosgene gas, which is -- shall we say -- slightlu harmful. (It was
one of the war gasses used during WWI).
I've heard that trichlor was outlawed, but I still see it around. My
favorite all-around solvent is MEK, but I haven't tried it on toner.

Phosgene is NOT produced from trichlor (1,1,1,trichloroethane).
Phosgene is carbonic dichloride, a compound with the deadly properties of
both chlorine AND carbon monoxide! TCE (trichloroethane,
methylchloroform, chlorothene) was produced as a safer substitute for
carbon tetrachloride back in the 60's and carbon tet was removed from the
market. IT IS CARBON TETRACHLORIDE that produces phosgene when it is
reduced on a hot surface. Carbon tet (tetrachloromethane) hasn't been
available for 30 years! Funny how legends continue to spread. :)

They sell it in every hardware store and lumber yard.
Chloro-clean is how I buy it. It is the #3 known carcinogen on the list,
down from the #1 chemical carcinogen, PCB (poly chlorinated biphenyls).
