Paper, toner, and dust particles can accumulate inside the printer and cause print quality problems, such as smearing or toner specks. Clean inside the printer to prevent these problems.

1. Power the printer off and unplug the power cord. Allow a reasonable amount of time for the printer to cool down.
2. Open the front cover and pull the toner cartridge straight out. Set it on a clean flat surface.




	Caution:
	To prevent damage, do not expose the toner cartridge to light for more than a few minutes.





	Caution:
	Do not touch the green underside of the toner cartridge. Use the handle on the cartridge to avoid touching this area.



3. With a dry and lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and the toner cartridge cavity.
   
   
   

   	Caution:
   	Do not touch the transfer roller inside the printer. Oil from your fingers may cause print quality problems.

   
   
   
4. Locate the long strip of glass Laser Scanning Unit (LSU) inside the top of the cartridge compartment, and gently swab the glass to see if dirt turns the white cotton black.



5. Reinsert the toner cartridge and close the front cover.
6. Plug in the power cord and power the printer on.
