TROUBLESHOOTING AND ROUTINE MAINTENANCE   

12 - 34

Replacing the drum unit

The MFC 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 MFC when you 
replace the drum unit. (See 

Cleaning the drum unit

 on page 12-27.)

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. 

WARNING

Just after you have used the MFC, some internal parts of the MFC 
are extremely 

HOT!

 So please be careful.

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.

HOT!
