Replacing Consumables • Toner Cartridge - Life expectancy approximately 3,000 pages for standard cartridges, 5,000 pages for high-capacity cartridges, assuming about 5% coverage, which means that 5% of the addressable dots in an image are printed with this color of toner. See "Toner Cartridge Replacement" on page 72. NOTE When installing a toner cartridge in a new image drum, the life expectancy of the cartridge will be reduced by approximately 1,500 pages (at 5% coverage) as the toner charges the new drum. • Image Drum - Life expectancy approximately 15,000 pages, assuming an average of 3 pages per print job. If the average print job is longer than this, the image drums could last longer, but if the average print job is shorter, then image drums will be used more quickly. See "Image Drum Replacement" on page 80. • Transfer Belt - Life expectancy about 50,000 letter-size pages. See "Belt Unit Replacement" on page 89. • Fuser - Life expectancy about 45,000 letter-size pages. See "Fuser Replacement" on page 95. Replacing Consumables • 71
