Note Actual life-expectancy can vary significantly based on print coverage, media type, length of print job, and
environmental conditions such as temperature and humidity.
The estimated life-expectancy of each supply and kit is based on the use of letter- or A4-size plain or laser
paper.

Print cartridges Black C8550A 25,000 pages Print cartridge life is directly proportional to the coverage of
toner on the page. Each color print cartridge prints
approximately 25,000 pages of letter-size or A4-size media
at 5-percent toner coverage (a full page of text), 50,000
pages at 2.5-percent coverage (a page partially covered with
text), and 12,500 pages at 10-percent coverage (a page with
text and graphics).
