Replacing a toner cartridgeC
The High Yield toner cartridges can print 
approximately 8,000 pages
1 and the 
Standard toner cartridges can print 
approximately 3,000 pages
1. Actual page 
count will vary depending on your average 
type of document (i.e., standard letter, 
detailed graphics). The machine is supplied 
with the Starter toner cartridge that will need 
to be replaced after approximately 2,000 
pages. When a toner cartridge is running low, 
the LCD shows Toner Low.
1Approx. cartridge yield is declared in accordance 
with ISO/IEC 19752.
Note
It is a good idea to keep a new toner 
cartridge ready for use when you see the 
Toner Low warning.
 
CAUTION 
HOT SURFACE
After you have just used the machine, some 
internal parts of the machine will be 
extremely hot. To prevent injury, when you 
open the front or back cover (back output 
tray) of the machine DO NOT touch the 
shaded parts shown in the illustration. If you 
do this you may get burned.
 
 
aPress the front cover release button and 
open the front cover. 
 
bSlowly take out the drum unit and toner 
cartridge assembly.
 
IMPORTANT
• We recommend that you put the drum unit 
and toner cartridge assembly on a clean, 
flat surface with a sheet of disposable 
paper or cloth underneath it in case you 
accidentally spill or scatter toner.
• To prevent damage to the machine 
caused by static electricity, DO NOT touch 
the electrodes shown in the illustration.

C
cPush down the blue lock lever and take 
the used toner cartridge out of the drum 
unit.
 
WARNING 
DO NOT put a toner cartridge into a fire. It 
could explode, resulting in injuries.
 
IMPORTANT
• Handle the toner cartridge carefully. If 
toner scatters on your hands or clothes, 
wipe or wash it off with cold water at once.
• To avoid print quality problems, DO NOT 
touch the shaded parts shown in the 
illustrations.
 
• Brother machines are designed to work 
with toner of a particular specification and 
will work to a level of optimum 
performance when used with genuine 
Brother toner cartridges (TN-3230/TN-
3280). Brother cannot guarantee this 
optimum performance if toner or toner 
cartridge of other specifications are used. 
Brother does not therefore recommend 
the use of cartridge other than genuine Brother cartridges with this machine, or 
the refilling of used cartridge with toner 
from other sources. If damage is caused 
to the drum unit or other part of this 
machine as a result of the use of toner or 
toner cartridge other than genuine Brother 
products due to the incompatibility or lack 
of suitability of those products with this 
machine, any repairs required as a result 
may not be covered by the warranty. 
• Unpack the toner cartridge just before you 
put it in the machine. If a toner cartridge is 
left unpacked for a long time, the toner life 
will be shortened.
• Be sure to seal up the used toner cartridge 
tightly in a suitable bag so that toner 
powder does not spill out of the cartridge.
 
dUnpack the new toner cartridge. Gently 
shake from side to side several times to 
distribute the toner evenly inside the 
cartridge.
 
ePull off the protective cover. 
 
						

							152
fPut the new toner cartridge firmly into 
the drum unit until you hear it lock into 
place. If you put it in correctly, the lock 
lever will lift automatically.
 
Note
Make sure that you put in the toner 
cartridge correctly or it may separate from 
the drum unit.
 
gClean the corona wire of the drum unit 
by gently sliding the blue tab from right 
to left and left to right several times.
 
Note
Be sure to return the blue tab to the home 
position (a) (1). If you do not, printed 
pages may have a vertical stripe.
 
hPut the drum unit and toner cartridge 
assembly back in the machine.
 
iClose the front cover.
Note
DO NOT turn off the machine or open the 
front cover until the LCD returns to the 
standby state.

Replacing the drum unitC
The machine uses a drum unit to create print 
images on paper. If the LCD shows 
Replace Drum, the drum unit is near the 
end of its life and it is time to buy a new one. 
Even if the LCD shows Replace Drum, 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 
Replace Drum appears), then the drum unit 
should be replaced. You should clean the 
machine when you replace the drum unit. 
(See Cleaning the laser scanner window 
on page 144.)
IMPORTANT
While removing the drum unit, handle it 
carefully because it may contain toner. If 
toner scatters on your hands or clothes, 
wipe or wash it off with cold water at once.
 
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 
approximately 25,000 pages
1. The actual 
number of pages your drum will print may 
be significantly less than this estimate. 
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.
1Drum yield is approximate, and may vary by type of 
use.
