regulations. 
Caution
■Wait to unpack the toner cartridge until immediately before you

cartridge provided with your DCP. We also strongly recommend 
that you continue to use only Genuine Brother Brand 
replacement toner cartridges. (TN-540 and TN-570).
Using or attempting to use potentially incompatible toner and/or 
toner cartridges in your DCP 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 toner and toner 
cartridges. To protect your investment and guarantee your print 
quality please continue to replace consumed toner cartridges

Replacing the drum unit
The DCP uses a drum unit to create print images on paper. If the 
LCD shows 
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 LCD 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 appears), then the drum 
unit should be replaced. You should clean the DCP when you 
replace the drum unit. (See Cleaning the drum unit
 on page 14-23.)
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 item, 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. 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.
