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.
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.
CAUTION
Brother multifunction machines are
designed to work with ink of a particular
specification and will work to a level of
optimum performance and reliability when
used with genuine Brother Branded ink
cartridges. Brother cannot guarantee this
optimum performance and reliability 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 ink from
other sources. If damage is caused to the
print head or other parts of this machine as
a result of using other brands of ink or ink
cartridges, any repairs required as a result
may not be covered by the warranty.
a Open the ink cartridge cover.
If one or more ink cartridges are empty,
for example Black, the LCD shows
B&W Print Only or Cannot Print.
b Press the lock release lever as shown to
release the cartridge indicated on the
LCD. Remove the cartridge from the
machine.
c Open the new ink cartridge bag for the
colour shown on the LCD, and then take
