Open the front cover and pull out the
drum unit and toner cartridge assembly.
2
Hold down the lock lever on the left and
pull the toner cartridge out of the drum
unit.
Note
Discard the used drum unit according to local
regulations, keeping it separate from
domestic waste. Be sure to seal the drum unit
tightly so toner powder does not spill out of
the unit. If you have questions, call your local
waste disposal office.

Reinstall the toner cartridge into the new
drum unit. If you put it in properly, the
lock lever will lift automatically.
WARNING
Just after you have used the DCP, some
internal parts of the machine are
extremely HOT! So please be careful.
CAUTION
To prevent damage to the printer from
static electricity, do not touch the
electrodes shown below.
CAUTION
Wait to unpack the new drum unit until
immediately before installing it. Place the
old drum unit into the plastic bag.
