Cleaning the drum unit6
If you have print quality problems, clean the drum unit as follows:
aPull the drum unit out from the printer and pull all the toner cartridge out from the drum unit.  See steps 
a to d in Replacing the drum uniton page 106-108.
bTurn the drum unit over by holding the green handle. Make sure that the drum unit gears (1) are on the 
left hand side.
 
CAUTION 
We recommend that you place the drum unit on a clean, flat surface with a piece of disposable paper 
underneath it in case you accidentally spill or scatter toner.
 
cSee the print sample to identify the color causing the problem. The color of the spots is the color of the 
drum you should clean. For example, if the spots are cyan, you should clean the drum for cyan. Put the 
print sample in front of the drum, and find the exact position of the poor print.

dTurn the drum unit gear toward you by hand while looking at the surface of the drum (1). 
eWhen you have found the mark on the drum that matches the print sample, wipe the surface of the drum 
gently with a cotton swab until the dust or paper powder on the surface comes off.
 
CAUTION 
DO NOT clean the surface of the photosensitive drum with a sharp object.
 
fTurn the drum unit gear toward you by hand to return it to the home position. The home position of each 
drum can be identified by matching the number on the drum unit gear to the same number on the side 
of the drum unit as shown in the illustration. Make sure that the number on each of the four drum unit 
gears matches the corresponding number on the side of the drum unit.
 
gUsing the green handles turn the drum unit back over.
hPut all the toner cartridges back in the drum unit and put the drum unit in the printer.  See steps f to h
