4Gently rock the toner cartridge from side 
to side five or six times to distribute the 
toner evenly inside the cartridge.
5Remove the protective cover.
CAUTION
■Brother strongly recommends that you 
do not refill the toner cartridge provided 
with your DCP. We also strongly 
recommend that you continue to use 
only Genuine Brother Brand 
replacement toner cartridges (TN-350). 
Using or attempting to use potentially 
incompatible toner and/or toner 
cartridges in your DCP may cause 
damage to the machine itself and/or it 
may result in unsatisfactory print 
quality. Our warranty coverage does 
not apply to any problem that was 
caused by the use of unauthorized 
third party toner and toner cartridges. 
To protect your investment and 
guarantee your print quality please 
continue to replace consumed toner 
cartridges with only Genuine Brother 
Branded Supplies.
■Wait to unpack the toner cartridge until 
immediately before you install it in the 
DCP. If a toner cartridge is left 
unpacked for a long period of time, the 
toner life is shortened.
CAUTION
Do not touch the shaded parts shown in 
the illustrations to prevent any degradation 
to the print quality.

6Insert the new toner cartridge in the 
drum unit until it clicks into place. If you 
put it in properly, the lock lever will lift

7Clean the primary corona wire inside the

from right to left several times. Return 
the blue tab to the Home position (

toner cartridge assembly.

assembly into the DCP.

Replacing the drum unit 
(DR-350)
The DCP uses a drum unit to create print 
images on paper. If the LCD shows 
Change Drum Soon, the drum unit is near 
the end of its life and it is time to buy a new 
one.
Even if the LCD shows 
Change Drum Soon, 
you may be able to continue printing without 
having to replace the drum unit for a while. 
However, if there is a noticeable deterioration 
in the output print quality (even before 
Change Drum Soon appears), then the 
drum unit should be replaced. You should 
clean the DCP when you replace the drum 
unit. (See  Cleaning the laser scanner window  
on page 6-17.)
Note
The drum unit is a consumable item, and it is 
necessary to replace it periodically. There are 
many factors that determine the actual drum 
life, such as temperature, humidity, type of 
paper and how much toner you use for the 
number of pages per print job. The estimated 
drum life is  up to 12,000 pages. The actual 
number of pages your drum will print may be 
significantly less than these estimates. 
Because we have no control over the many 
factors that determine the actual drum life, we 
cannot guarantee a minimum number of 
pages that will be printed by your drum.
CAUTION
When removing the drum unit, handle it 
carefully because it contains toner. If toner 
scatters and your hands or clothes get 
dirty, immediately wipe or wash it off with 
cold water.

1Open the front cover and pull out the 
drum unit and toner cartridge assembly. 
2Hold 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.
3Reinstall 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.
