Brother HL-4000CN Yellow Toner

The TN-11 Black toner cartridge yields up to 8,500 pages while each of the TN-11 Color toner cartridges yields up to 6,000 pages when printing at 5% coverage on A4/ Letter sized paper. To produce all the colors you see on a page, the individual toners are mixed during the printing process. This mixing of the four-toner colors allows the printer to print in rich vibrant color shades. The Black toner cartridge has a higher yield because black is the Key color for monochrome and color printing.
