media  on page 10.) 
Printing appears dirty or ink seems 
to run. Make sure you are using the recommended types of paper. (See 
Acceptable 
paper and other media  on page 10.) Dont handle the paper until the ink is dry.
If you are using photo paper, make sure that you have set the correct paper type.

neatly. Make sure you are using the paper support flap. (See 
Loading paper and other 
media  on page 14.)
Printed pages refeed and cause a 
paper jam. Make sure you pull out the paper support until it clicks.

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  +(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  - ( 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 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.
  
Brother multifunction machines are 
designed to work with ink of a particular 
specification and will work to a level of 
optimum performance when used with 
genuine Brother Branded ink cartridges. 
Brother cannot guarantee this optimum 
performance if ink or ink cartridges of other 
specifications are used. Brother does not 
therefore recommend the use of cartridges 
other than genuine Brother Branded 
cartridges or the  refilling of empty 
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 
incompatible products with this machine, 
any repairs required as a result may not be 
covered by the warranty.
