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.
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 that an ink 
cartridge is empty, 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.
aOpen the ink cartridge cover.
If one or more ink cartridges are empty, 
for example Black, the LCD shows 
Ink Empty  and Black.

gThe machine will automatically reset the 
ink dot counter.
Note
• If you replaced an ink cartridge, the LCD may ask you to verify that it was a brand 
new one. (For example, 
Did You Change Black ) For each 
new cartridge you installed, press  1(Yes ) 
to automatically reset the ink dot counter 
for that color. If the ink cartridge you 
installed is not a brand new one, be sure 
to press  2 ( No ).
• If the LCD shows  No Cartridge after 
you install the ink cartridges, check that 
the ink cartridges are installed properly.
 
WARNING 
If ink gets in your eyes, wash them out with 
water at once and call a doctor if you are 
concerned.
 
CAUTION 
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 stains your skin or clothing, wash with 
soap or detergent at once. 
  
If you mix the colors 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.
  
Brother strongly recommends that you do 
not refill the ink cart ridges provided with 
your machine. We also strongly 
recommend that you continue to use only 
Genuine Brother Brand replacement ink 
cartridges. Use or attempted use of 
potentially incompatible ink and/or 
cartridges in the Brother machine may 
cause damage to the machine and/or may 
result in unsatisfactory print quality. Our 
warranty coverage does not apply to any 
problem that is caused by the use of 
unauthorized third party ink and/or 
cartridges. To protect your investment and 
obtain premium performance from the 
Brother machine, we strongly recommend 
the use of Genuine Brother Supplies.
