In rotary development, four Developer Assemblies rotate in sequence;...
  • Page 67 EPSON EPL-C8000 Rev. B o As the printer prints more pages, the toner in the developer decreases. To maintain proper developer density, it is necessary to resupply toner to the Developer Assembly from the Toner Cartridge. This is called ‘Toner Dispensing.’ The Toner Dispensing mechanism uses two types of controls (PCDC and ADC).
