CHAPTER 5 PERIODIC MAINTENANCE
!
CAUTION:
• Handle the drum unit and toner cartridge carefully. If toner scatters on your hands or
clothes, wipe or wash it off with cold water immediately.
• Be sure to seal the toner cartridge tightly so that toner powder does not spill out of the
cartridge.
• Dispose of the used toner cartridge in accordance with local plastic waste regulations.
• Only unpack a toner cartridge immediately before you need to install it into the machine. If
a toner cartridge is left unpacked for a long period of time, the toner life is shortened
• If an unpacked drum unit is subjected to excessive direct sunlight or room light, the unit
may be damaged.
• Use a Brother genuine toner cartridge which is specially formulated to ensure top print
quality.
• Printing with a 3rd party toner or toner cartridge may reduce not only the printing quality but
also the quality and life of the machine itself. It may also cause serious damage to the
performance and life of a genuine Brother drum unit. Warranty cover is not applied to
problems caused by the use of 3rd party toner or toner cartridges.
• Brother strongly recommends that you do not refill the toner cartridge provided with the
machine. We also strongly recommend that you continue to use only Genuine Brother
Brand replacement toner cartridges. Using or attempting to use potentially incompatible
toner and/or toner cartridges in the machine may cause damage to the machine itself
and/or it may result in unsatisfactory print quality.
• Make sure that the wire cleaner on the drum unit is returned to the home position (
position) before re-installing the drum unit into the machine, or printed pages may have
vertical stripes.
• Install the toner cartridge immediately after you remove the protective cover. Do not touch
the development roller and photosensitive drum shaded as shown below;
NOTE:
(1) It is recommended to clean the machine when you replace the toner cartridge. Refer to
subsection 3. 'PERIODICAL CLEANING' in this
