Replacing the ink cartridges
Your machine is equipped with an ink dot counter. The ink dot 
counter automatically monitors the level of ink in each of the four 
cartridges. When the machine detects an ink cartridge is running out 
of ink, the machine will notify you with a message on the LCD.
The LCD will inform 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 informs you that an ink cartridge is empty, 
there will be a small amount of ink remaining 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.
1Lift the scanner cover from the right-hand side of the machine 
until it locks securely into the open position.
If one or more ink cartridges are empty, for example Black, the 
LCD shows  Ink Empty Black  and Replace Ink .
2Pull the ink cartridge hook toward you and remove the ink 
cartridge for the color shown on the LCD.
3Open the new ink cartridge bag for the color shown on the LCD, 
and then take out the ink cartridge.

5Each color has its own correct position. Keep the ink cartridge 
in an upright position when you insert it into slot. Press down 
firmly on the ink cartridge until the hook snaps over it.
6Lift the scanner cover to release the lock. Gently push the 
scanner cover support down and close the scanner cover.
7If you replaced an ink cartridge while Near Empty was 
displayed on the LCD, the LCD may ask you to verify that it was 
a brand new one. Example:  Did You Change Blck? 
▲ Yes 
▼ No . For each  new cartridge you installed, press  (Yes ) to 
automatically reset the ink dot counter for that color. If the ink 
cartridge you installed is not a brand new one, please be sure to 
select  ( No).
Do not touch the area shown in the illustration above.
If the protective yellow cap comes off when you open the bag 
the cartridge will not be damaged.
If you wait until  Ink Empty message is displayed on the LCD, 
the machine will automatically reset the ink dot counter.

WARNING
If ink gets in your eyes, irrigate them with water immediately and call 
a doctor if you are concerned.
Caution
■Do not remove 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 
immediately.
■ If you install an ink cartridge in the wrong color position, you must 
clean the print head several times before you start printing (after 
correcting the cartridge installation) because the colors were 
mixed.
■ 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 
cartridges provided with your machine. We also strongly 
recommend that you continue to use only Genuine Brother Brand 
replacement ink cartridges. Using or attempting to use potentially 
incompatible inks and/or cartridges in your machine may cause 
damage to the machine itself and/or it may result in unsatisfactory 
print quality. Our warranty coverage does not apply to any 
problem that was caused by the use of unauthorized third party 
ink and/or cartridges. To protect your investment and guarantee 
your print quality please continue to replace consumed ink 
cartridges with only Genuine Brother Branded Supplies.
If the  Install  message is on the display after you have 
installed ink cartridges, check that the ink cartridges are 
installed properly.
