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 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
immediately.
■ If you install an ink cartridge in the wrong color 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.
■ Do not dismantle or tamper with the ink cartridge; this can cause
the ink to leak out of the cartridge.
■ 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.
