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
display Ink low (name of color).
You should purchase a replacement
cartridge in preparation for when the
machine indicates the color is completely
empty.
When one of the ink cartridge is empty,
the LCD will display Cannot Print or
B&W Print Only
.
You should only replace the actual ink
cartridge when this message Cannot
Print
or B&W Print Only 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 to replace
ink cartridge, 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.
