WARNING
If ink gets in your eyes, irrigate them with water immediately and
consult 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 printer
will not know the quantity of ink left in the cartridge.
DO NOT shake the ink cartridges, because the ink may spill when
you take off the sealing tape.
If ink stains your body or clothing, wash with soap or detergent
immediately.
If you install an ink cartridge in the wrong colour 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.
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 INK EMPTY message is on the display after you have
installed ink cartridges, check that the ink cartridges are
installed correctly.
If you still cannot solve a problem with your machine, call your dealer
for service.
