How to replace the Toner Cartridge
When the Standard Capacity toner cartridge is used, the printer can print approximately 3,000
pages at 5% coverage on A4/Letter size paper with one toner cartridge.  When the High
Capacity toner cartridge is used, approximately 6,000 pages can be printed under the same
conditions.  When the toner cartridge is running low, the Alarm
 and Data
 (Toner) LEDs
blink once every 5 seconds to indicate the toner is depleted and will soon run out.
2Note
· Actual page count will vary depending on your average document type. (i.e. standard
letter, detailed graphics, etc.)
· We  recommend that you always keep a new toner cartridge ready for use in case you get a
toner low warning.
· Discard the used toner cartridge according to your local regulations. If you are not sure of
them, consult your local dealer.  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.
· We recommend that you clean the printer when you replace the toner cartridge. See “How
to clean the printer” in this chapter. You can view a demonstration on the CD video.
· There are many factors that determine the actual toner life, such as temperature, humidity,
the type of paper that you use, the number of pages per print job, etc.  Under ideal
conditions, the average toner life is estimated at approximately 3,000 pages (Standard
Capacity toner cartridge) / 6,000 pages (High Capacity toner cartridge).  The actual
number of pages that your toner will print may be significantly less than this estimate.
Because we have no control over the many factors that determine the actual toner life, we
cannot guarantee a minimum number of pages that will be printed by your toner.

Fig.3-6  Remove the protective cover
!Caution

Wait to unpack the toner cartridge until immediately before you are ready to install it into
the printer. If toner cartridges are 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 only a genuine Brother toner cartridge which is specially formulated to ensure top
print quality.

Printing with a 3rd party toner or 3rd party toner cartridge may reduce not only the print
quality but also the quality and life of the printer itself.  It may also cause serious damage
to the performance and life of a genuine Brother drum unit.  Warranty coverage does not
apply to problems caused by the use of 3rd party toner or 3rd party toner cartridges.

Printing with a 3rd party drum unit or OPC drum may reduce not only the print quality but
also the quality and life of the printer itself.  It may also cause serious damage to the
performance and life of a genuine Brother drum unit.  Warranty coverage does not apply to
problems or damage caused by the use of a 3rd party drum unit or OPC drum.

Install the toner cartridge immediately after you remove the protective cover. Do not touch
the shaded part shown below.

How to replace the Drum Unit
The printer uses a drum unit to create the print images on paper.  If the Drum LED is lit it
indicates the drum unit is near the end of its life.  Purchase a new drum unit to replace the
current one.  Even if the Drum LED is on, you may be able to continue to print without
replacing the drum unit for a while.  However, if there is a noticeable deterioration in the
output print quality even before the Drum LED lights, then the drum unit should be replaced.
You should clean the printer when you replace the drum unit.  See “How to clean the printer”
in this chapter and in the instructional video on the supplied CD-ROM.

!Caution
When removing the drum unit, handle it carefully because it contains toner.
2Note

The drum unit is a consumable, and it is necessary to replace it periodically.

There are many factors that determine the actual drum life, such as temperature, humidity,
type of paper and toner that you use, the number of pages per print job, etc.  Under ideal
conditions, the average drum life is estimated at approximately 20,000 pages.  The actual
number of pages that your drum will print may be significantly less than this estimate.
Because we have no control over the many factors that determine the actual drum life, we
cannot guarantee a minimum number of pages that will be printed by your drum.

For best performance, use only genuine Brother toner.  The product should be used only in
a clean, dust-free environment with adequate ventilation.
