Toner cartridge
A new toner cartridge can print approximately 3,500 (standard cartridge) or approximately 7,000 (high yield 
cartridge) A4 or Letter size single-sided pages at 5% coverage.
Note

TONER LOW Message
(Appears at intervals.)
 
TONER LOW
If the LCD shows TONER LOW, the printer has nearly run out of toner. Buy a new toner cartridge and have it 
ready before you get a TONER LIFE END message. To replace the toner cartridge, see Replacing the toner 
cartridge on page 75.
TONER LIFE END message
 
TONER LIFE END
If the LCD shows TONER LIFE END, the printer has run out of toner or the toner is not evenly distributed 
inside the cartridge.
In both situations, the printer will stop printing until a new toner cartridge has been put into the printer.
TONER LIFE END can only be cleared by putting a new toner cartridge into the drum unit.

CAUTION 
Wait to unpack the toner cartridge until immediately before you put it in the printer. If toner cartridges are 
left unpacked for a long time the toner life will be shortened.
  If an unpacked drum unit is put in direct sunlight or room light, the unit may be damaged.  Put the toner cartridge in the drum unit immediately after you have removed the protective cover. To prevent 
any degradation to the print quality, DO NOT touch the shaded parts shown in the illustrations.
 
CAUTION 
For USA and Canada  Brother strongly recommends that you do not refill the toner cartridge provided with your printer. We also 
strongly recommend that you continue to use only genuine Brother brand replacement toner cartridges. Use 
or attempted use of potentially incompatible toner and/or cartridges in the Brother machine may cause 
damage to the machine and/or may result in unsatisfactory print quality. Our warranty coverage does not 
apply to any problem that is caused by the use of unauthorized third party toner and/or cartridges. To protect 
your investment and obtain premium performance from the Brother machine, we strongly recommend the 
use of genuine Brother supplies.
 
CAUTION 
For UK and other countries  Brother machines are designed to work with toner of a particular specification and will work to a level of 
optimum performance when used with genuine Brother branded toner cartridges. Brother cannot guarantee 
this optimum performance if toner or toner cartridges of other specifications are used. Brother does not 
therefore recommend the use of cartridges other than genuine Brother branded cartridges with this 
machine.
  If damage is caused to the drum unit or other part of this machine as a result of using other manufacturer’s 
products with this machine, any repairs required as a result may not be covered by the warranty.

Drum unit
A new drum unit can print approximately 25,000 A4 or Letter size single-sided pages at 5% coverage.
Note
• There are many factors that determine the actual drum life, such as the temperature, humidity, type of 
paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average 
drum life is estimated at approximately 25,000 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 printer should be used only in a clean, dust-
free environment with adequate ventilation.
• Printing with a third-party drum unit may reduce not only the print quality but also the quality and life of the 
printer itself. Warranty coverage does not apply to problems caused by the use of a third-party drum unit.
 
DRUM NEAR END message
 
DRUM NEAR END
If the LCD shows DRUM NEAR END, it means the drum unit is near the end of its life. We recommend that 
you replace the drum unit with a new one before there is a noticeable deterioration in the print quality.
