Note Life-expectancy of supplies The following tables list the approximate schedule for replacing supplies and kits, and the part number for each supply or kit. To order supplies, see "Ordering supplies" on page 175. 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 letter- or A4-size plain or laser paper.
