CHANGE DRUM SOON  

 
 

The printer uses a Drum Unit to create the print images on paper.  If the 
display shows the above message, 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.

There are many things that affect how long the drum unit lasts for, such as 
the temperature, humidity, type of paper, type of toner used, the number of 
pages in each print job and so on.  Under ideal conditions, a drum unit will 
last for upto 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 things that affect the actual drum life, we cannot 
guarantee a minimum number of pages that your drum will print. 
For best performance, only use genuine Brother toner.  You  should only use 
the printer in a clean, dust-free environment with suitable ventilation.
