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.
bPull the lock release lever down and 
take out the ink cartridge for the color 
shown on the LCD.
  
cOpen the new ink cartridge bag for the 
color 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.
 
 
Note
If the protective yellow caps come off 
when you open the bag, the cartridge will 
not be damaged.

eEach color has its own correct position. 
Insert the ink cartridge in the direction of 
the arrow on the label.
 
fLift the 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 Black) 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, be 
sure to press - (No).
If you wait until the LCD shows 
Near Empty and Ink Empty, the 
machine will automatically reset the ink 
dot counter.
Note
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.
