Routine maintenance B
Replacing the ink cartridges B
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.
Note
For example, when one of the ink
cartridge is nearly empty, the LCD will
disply Near Empty (name of colour).
You should purchase a replacement
cartridge in preparation for when the
machine indicates the colour is completely
empty.
When one of the ink cartridge is empty,
the LCD will display Ink Empty (name of
colour).
You should only replace the actual ink
cartridge when this message Ink Empty
appears 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.
a Open the ink cartridge cover.
If one or more ink cartridges are empty,
for example Black, the LCD shows
Ink Empty Black and
Replace Ink.
