• Toner Cartridge — Life expectancy approximately 5,000 pages,
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 219.
•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 226.
•Transfer Belt — Life expectancy about 50,000 letter-size pages.
See “Belt Unit Replacement” on page 235.
• Fuser — Life expectancy about 45,000 letter-size pages. See
“Fuser Replacement” on page 240.
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.
