Developing Unit Removal
1. Open the printer upper doors. (See page 116.)
2. Prepare a large plastic bag in which to put the developing unit.
3. Remove the developing unit (page 129) and place it in the
plastic bag, making sure it is still accessible.
4. If you are replacing the developing unit, dispose of the old unit
properly, remove the new developing unit from its package, and
go to step 11. If you are just replacing the developer, continue
with step 5.
5. Turn the toner cartridge knob counterclockwise until it stops,
then remove the cartridge from the developing unit.
