Routine maintenanceB
Replacing the ink cartridgesB
Your machine is equipped with an ink dot 
counter. The ink dot counter automatically 
monitors the level of ink in each of the 4 
cartridges. When the machine detects an ink 
cartridge is running out of ink, the machine 
will tell you with a message on the LCD.
Note
For example, when one of the ink 
cartridge is nearly empty, the LCD will 
display Ink low  (name of colour).
You should purchase a replacement 
cartridge in preparation for when the 
machine indicates the colour is completely 
empty.
When one of the ink cartridge is empty, 
the LCD will display  Cannot Print or 
B&W Print Only .
You should only replace the actual ink 
cartridge when this message 
Cannot Print  or B&W Print Only  
appears on the LCD.
 
The LCD will tell you which ink cartridge is low 
or needs replacing. Be sure to follow the LCD 
prompts to replace the ink cartridges in the 
correct order.
Even though the machine tells you to replace 
an ink cartridge, there will be a small amount 
of ink left in the ink cartridge. It is necessary 
to keep some ink in the ink cartridge to 
prevent air from drying out and damaging the 
print head assembly.
IMPORTANT
Brother multifunction machines are 
designed to work with ink of a particular 
specification and will work to a level of 
optimum performance and reliability when 
used with genuine Brother Original ink 
cartridges. Brother cannot guarantee this 
optimum performance and reliability if ink 
or ink cartridges of other specifications are 
used. Brother does not therefore 
recommend the use of cartridges other 
than genuine Brother Original cartridges 
or the refilling of used cartridges with ink 
from other sources. If damage is caused 
to the print head or other parts of this 
machine as a result of using other brands 
of ink or ink cartridges, any repairs 
required as a result may not be covered by 
the warranty.

fGently push the ink cartridge until it 
clicks, and then close the ink cartridge 
cover.
 
gThe machine will automatically reset the 
ink dot counter.
Note
• If you replaced an ink cartridge, for example Black, the LCD may ask you to 
verify that it was a brand new one 
(Did You Change Blck? ). For each 
new cartridge you installed, press  a ( Yes ) 
to automatically reset the ink dot counter 
for that colour. If the ink cartridge you 
installed is not a brand new one, be sure 
to press  b ( No ).
• If the LCD shows  No Cartridge or 
Cannot Detect  after you install the ink 
cartridge, check that the ink cartridges are 
installed correctly.
 
CAUTION 
If ink gets in your eyes, wash them out with 
water at once and call a doctor if you are 
concerned.
 
IMPORTANT
• DO NOT take out ink cartridges if you do  not need to replace them. If you do so, it 
may reduce the ink quantity and the 
machine will not know the quantity of ink 
left in the cartridge.
• DO NOT touch the cartridge insertion  slots. If you do so, the ink may stain your 
skin.
• If ink gets on your skin or clothing  immediately wash it off with soap or 
detergent.
• If you mix the colours by installing an ink  cartridge in the wrong position, clean the 
print head several times after correcting 
the cartridge installation.
• Once you open an ink cartridge, install it in  the machine and use it up within six 
months of installation. Use unopened ink 
cartridges by the expiration date written on 
the cartridge package.
• DO NOT dismantle or tamper with the ink  cartridge, this can cause the ink to leak out 
of the cartridge.
