Toner cartridge utilizes a revolutionary toner manufacturing process where toner is chemically grown and processed into very small and consistent particles, resulting in sharper, high-gloss image quality, an increased range of colors, enhanced fine-line detail and superior reliability. Longer-life toner cartridge reduces the need for customer interaction with the machine. Use this cartridge with Xerox Phaser EX7750 and 7750.
