3. Maintenance
Redistributing toner
When the toner cartridge is near the end of its life:
White streaks or light printing occurs and/or density variation 
side to side.
The Status LED blinks red. 
If this happens, you can temporarily improve print quality by 
redistributing the remaining toner in the cartridge. In some cases, 
white streaks or light printing will still occur even after you have 
redistributed the toner.

Open the front cover and pull the toner cartridge out.
Thoroughly roll the cartridge five or six times to distribute the 
toner evenly inside the cartridge.
 
If toner gets on your clothing, wipe it off with a dry cloth and 
wash clothing in cold water: hot water sets toner into fabric.
