Redistributing Toner
When the toner cartridge is near the end of its life, white streaks or light print occurs. The LCD displays the
warning message, Toner Low. Thoroughly shake the cartridge from side-to-side 5 or 6 times to distribute
the toner evenly inside the cartridge and temporarily improve print quality.
This is not intended to be a long term method of correction, but meant to assist your printing needs until you
obtain a new cartridge assembly.
