Redistributing Toner
When the toner cartridge is near the end of its life, white
streaks or light printing occurs. The LCD displays the warning
message, “[Toner Low]”. You can temporarily reestablish print
quality by redistributing the remaining toner in the cartridge. In
some case, white streaks or light printing still occurs even after
you have redistributed the toner.

Pull the toner cartridge out and remove it from the printer.

Gently shake the toner cartridge from side to side five or
six times to redistribute the toner.
