(See Replacing the Drum Unit on page 17-26.)
4Close the front cover.
5Plug in the power cord first, then the telephone cord.
Replacing the Toner Cartridge
The machine can print up to 6,000 pages using a high yield toner
cartridge.  When the toner cartridge is running low, the display shows
TONER LOW.  The machine is supplied with a standard toner cartridge
that must be replaced after approximately 3,000 pages.  Actual page count
will vary depending on your average document type (i.e., standard letter,
detailed graphics).
It is a good idea to keep a new toner cartridge ready for use when you see
the toner low warning.
Discard the used toner cartridge according to local regulations.  If you are
not sure of them, consult Brother Customer Service.  Be sure to seal the
toner cartridge tightly so toner powder does not spill out of the cartridge.
When discarding used toner cartridges, keep them separate from domestic
garbage.
We recommend that you clean the machine when you replace the toner
cartridge.
Toner Empty Indicator
When the toner cartridge is running low, the display shows TONER LOW
and the Toner Empty icon on the control panel flashes on and off to
indicate the toner is low.
              
DisplayToner Empty Icon
The Toner Empty icon appears and the display shows TONER EMPTY.
Once this icon appears, your machine will not resume printing until you
install a new toner cartridge.

Caution
nWait to unpack the toner cartridge until immediately before you install it
into the machine.  If a toner cartridge is left unpacked for a long period of
time, the toner life is shortened.
nYou can use only a genuine Brother toner cartridge (TN-430 or TN-460),
which is specially formulated to ensure top print quality.  Using another
brand of toner cartridge may void your machineÕs warranty.
4Gently rock the toner cartidge

8Reinstall the drum unit
and close the front cover.
Replacing the Drum Unit
The machine uses a drum unit to create print images on paper.  If the
screen displays CHANGE DRUM SOON, the drum unit is near the end of
its life and it is time to purchase a new one.
Even if the display shows CHANGE DRUM SOON, you may be able to
continue printing without having to replace the drum unit for a while.
However, if there is a noticeable deterioration in the output print quality
(even before CHANGE DRUM SOON is shown), then the drum unit
should be replaced.  You should clean the machine when you replace the
drum unit. (See page 17-22.)
Caution
When removing the drum unit, handle it carefully because it contains
toner. If toner scatters and your hands or clothes get dirty, immediately
wipe or wash with cold water.
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 how much toner you
use for the number of pages per print job, etc.  The estimated drum life is
up to 20,000 pages. The actual number of pages your drum will print may
be significantly less than these estimates.  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.
WARNING
Just after you have used

internal parts of the

careful.
