fWhile holding both hands, turn the drum 
unit upside down and place on a piece of 
disposable paper or cloth. Make sure 
that the drum unit gears (1) are on your 
left hand side.
 
gSee the print sample to identify the 
colour causing the problem. The colour 
of the spots is the colour of the drum you 
should clean. For example, if the spots 
are cyan, you should clean the drum for 
cyan. Put the print sample in front of the 
drum, and the find the exact position of 
the repeating mark.
 
hTurn the drum unit gear on the drum that 
matches that mark (for example, for a 
cyan mark, turn the drum for cyan). You 
should see the mark eventually on the 
surface of the drum (1).
 
iWhen you have found the mark on the 
drum that matches the print sample, 
wipe the surface of the drum gently with 
a cotton swab until the dust or paper 
powder on the surface comes off.
 
CAUTION 
The drum is photosensitive so DO NOT 
touch it with your fingers.
  
DO NOT clean the surface of the 
photosensitive drum with a sharp object.
  
DO NOT use excessive force when 
cleaning the drum surface.

jTurn the drum unit gear toward you by 
hand to return it to the home position. 
The home position of each drum can be 
identified by matching the number on 
the drum unit gear to the same number 
on the side of the drum unit as shown in 
the illustration. Make sure that the 
number on each of the four drum unit 
gears matches the corresponding 
number on the side of the drum unit.
 
kHolding the toner cartridges by their 
coloured handles, insert them one by 
one back into the drum unit as shown. 
Make sure that you match the toner 
cartridge colour to the same colour label 
on the drum unit, and make sure that 
you fold down the toner cartridge 
handle (A) once the toner cartridge is in 
place. Repeat this for all the toner 
cartridges.

The following are maintenance messages that appear alternately with the normal message on the 
upper row of the LCD when the machine is in the Ready mode. These messages advise you that 
you will need to replace each of the consumable items as soon as possible, since the consumable 
item’s end of life has been reached. The machine will continue printing when any of these 
messages appear on the LCD.
1When printing on Letter or A4 size paper. The actual number of printed pages will vary depending on the print jobs 
and paper you use.
Note
• Discard used consumable items according to local regulations, keeping it separate from 
domestic waste. If you have questions, call your local waste disposal office. Be sure to reseal 
the consumable items tightly so that the material inside does not spill.
• We recommend placing used consumable items on a piece of paper to prevent accidentally 
spilling or scattering the material inside.
• If you use paper that is not a direct equivalent for the recommended paper, the life of 
consumable items and machine parts may be reduced.
•
The projected life for toner cartridges and a waste toner box is based on an average 5% coverage 
of the printable area using any colour toner cartridge. Frequency of replacement will vary 
depending on the complexity of printed pages, percentage of coverage and type of media used.

CAUTION 
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-130/TN-135). Brother 
cannot guarantee this optimum 
performance if toner or toner cartridges of 
other specifications are used. Brother does 
not therefore recommend the use of 
cartridges other than genuine Brother 
cartridges with this machine, or the refilling 
of empty cartridges 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 cartridges 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.
 
Note
• Be sure to seal up the toner cartridge 
tightly in a suitable bag so that toner 
powder does not spill out of the cartridge.
• Discard the used toner cartridge 
according to local regulations, keeping it 
separate from domestic waste. If you have 
questions, call your local waste disposal 
office.
