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 Black and 
Replace Ink.
bPull the lock release lever down and 
take out the ink cartridge for the colour 
shown on the LCD.
  
cOpen the new ink cartridge bag for the 
colour shown on the LCD, and then take 
out the ink cartridge.
dRemove the protective yellow cap (1). 
Improper Setup 
DO NOT touch the area shown in the 
illustration below.

							92
Note
If the protective yellow caps come off 
when you open the bag, the cartridge will 
not be damaged.
 
eEach colour has its own correct position. 
Insert the ink cartridge in the direction of 
the arrow on the label.
 
fLift each lock release lever and push it 
until it clicks, and then close the ink 
cartridge cover.
 
gIf you replaced an ink cartridge the LCD 
may ask you to verify that it was a brand 
new one. (For example, 
Did You Change Blck?) For each 
new cartridge you installed, press 1 
(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 2 (No).
If you wait until the LCD shows Near 
Empty or Ink Empty, the machine will 
automatically reset the ink dot counter.
Note
If the LCD shows Install 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 this machine 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.
 
Cleaning the outside of the 
machineB
CAUTION 
Use neutral detergents. Cleaning with 
volatile liquids such as thinner or benzine 
will damage the outside surface of the 
machine.
  
DO NOT use cleaning materials that 
contain ammonia.
  
DO NOT use isopropyl alcohol to remove 
dirt from the control panel. It may crack the 
panel.
 
Clean the outside of the machine as 
follows:
B
aPull the paper tray (1) completely out of 
the machine.
 
bWipe the outside of the machine with a 
soft cloth to remove dust.

Cleaning the print headB
To ensure the good print quality, the machine 
will regularly clean the print head. You can 
start the cleaning process manually if 
needed.
Clean the print head and ink cartridges if you 
get a horizontal line in the text or graphics on 
your printed pages. You can clean Black only, 
three colours at a time 
(Yellow/Cyan/Magenta), or all four colours at 
once.
Cleaning the print head consumes ink. 
Cleaning too often uses ink unnecessarily.

times and the print has not improved, call 
your Brother dealer.

Packing and shipping 
the machine
B
When you transport the machine, use the 
packing materials that came with your 
machine. If you do not pack the machine 
properly, you could void your warranty.
CAUTION 
It is important to allow the machine to ‘park’ 
the print head after a print job. Listen 
carefully to the machine before unplugging 
it to make sure that all mechanical noise 
has stopped. Not allowing the machine to 
finish this parking process may lead to print 
problems and possible damage to the print 
head.
 
aOpen the ink cartridge cover.
bPull the lock release levers down and 
take out all the ink cartridges. (See 
Replacing the ink cartridges on page

cover.
 
CAUTION 
If you are not able to find the yellow 
protective parts, DO NOT remove the ink 
cartridges before shipping. It is essential 
that the machine be shipped with either the 
yellow protective parts or the ink cartridges 
in position. Shipping without them will 
cause damage to your machine and may 
void your warranty.

wall socket and take the telephone line 
cord out of the machine.
eUnplug the machine from the electrical 
socket.
