Apple ColorLaserWriter 12/600PS - Manual (Page 321)

16 Remove all the fuser oil from inside the printer.
First, use a lever inside the fuser access door to pump fuser oil from inside
the printer back into the fuser oil compartment. Then insert a turkey baster or
other blunt syringe into the fuser oil compartment and withdraw the oil.
IMPORTANT Do not use paper towels, tissues, or anything that leaves lint or
debris. It’s better to leave a small amount of oil than to get foreign matter into
the compartment.
If you leave oil in the printer, spots may appear on the first 20 to 50 pages
you print after the move.
To force fuser oil out of the
printer and back into the
fuser oil compartment, press
and release this lever 50
times (or more, if necessary).
