Ordering supplies The following table lists the approximate schedule for replacing supplies and kits, and the part number for each supply or kit. Note 7 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.

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). HP recommends that you place an order for a replacement print cartridge when the ORDER CARTRIDGE message first appears on the control panel display. ENWW Ordering supplies 175
