4. If toner is not level at the port, then the toner in the Toner Dispense
Assembly has been augered into the Developer but no fresh toner is being
delivered from the Toner Cartridge to the Toner Dispense Assembly.
Note The Auger Toner level may also appear low if it was
recently emptied by heavy printing and has not yet been
completely filled up by successive dispense cycles.
