The MFC uses a drum unit to create the print images on paper. If the LCD shows 

, the drum unit is near the end of its life. Purchase a 

new drum unit to replace the current one.

Even if the LCD shows 

, 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 

 is shown, then the drum unit should be replaced. You should 

clean the MFC when you replace the drum unit.

■

When removing the drum unit, handle it carefully because it contains toner.  
When you replace the drum unit, you should clean the MFC.

■

Wait to unpack the drum unit until immediately before installing it into the MFC. 
If an unpacked drum unit is subjected to excessive direct sunlight or room light, 
the unit may be damaged.

■

Handle the toner cartridge and the drum unit carefully because they contain 
toner. If toner scatters and your hands or clothes get dirty, immediately wipe or 
wash with cold water.

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

Just after you have used the MFC, some internal parts of the machine are 
extremely HOT! So please be careful.

Follow these steps to replace the drum unit:

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 toner that you use and the number of pages per print 
job, etc. The drum life is estimated at approximately 20,000 pages at 20 pages per 
job and 8,000 pages at 1 page per job. 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.
