Cleaning the Machine
To avoid print quality problems, the interior of the machine must be cleaned with every toner container replacement.
1
Open the front cover.
2
Lift the developer unit together with the toner container 
out of the machine.
3
Remove the drum unit from the machine by holding the 
green levers with both hands.
NOTE: 
The drum unit is sensitive to light. Never expose the 
drum unit to light for more than five minutes.
4
Place the drum unit flat on a clean, level surface.
IMPORTANT: 
Do not place the drum unit on end.
5
Use a clean, lint free cloth to clean dust and dirt away 
from the metal registration roller.
IMPORTANT: 
Take care not to touch the transfer roller 
(black) during cleaning.
