Cleaning the Printer
The paper transfer unit should be cleaned each time the toner container 
and waste toner box are replaced. 
To maintain optimum print quality, it is also recommended that the inside 
of the printer be cleaned once a month as well as when the toner 
container is replaced. 
It should also be cleaned if streaking or lines appear on printed copies, or 
if printouts appear faint or blurred.
Cleaning the Paper Transfer Unit
Print problems such as soiling of the reverse side of printed pages may 
occur if the paper transfer unit becomes dirty. To clean the paper transfer 
unit, you must use the dry cloth.
1 Pull up the rear cover lever and open the rear cover.
2 Wipe away the paper dust on the registration roller and the paper 
ramp using the cleaning cloth.
3 Close the rear cover.
Note  Be careful not to touch the black transfer roller and 
brown transfer belt during cleaning as this may adversely 
affect print quality.
