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 Toner LED blinks orange. 
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.
Before opening the front cover, close the output support first.
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.
