Checking the Drum Life
You can see the percentage of the drum’s life that remains available.
1
Press Menu, 2, 0, 3. 
2
For five seconds, the LCD shows the available 
percentage of drum life.
Discard the used drum unit according to local regulations, keeping it separate 
from domestic waste. Be sure to seal the drum unit tightly so toner powder does 
not spill out of the unit. If you have questions, call your local waste disposal 
office.
Even if the remaining drum life is 0%, you may continue to use the drum unit 
until you have a print quality problem.
