HowHPMeasuresInkPageYields
Some HP inkjet printers use ink from the first cartridges installed for printer start up. This one-time ink usage is not included in the ISO
24711 test, and could impact the yield for your very first cartridge. Also, some HP inkjet printers include an "introductory cartridge" in
the printer box, which may print less than an HP replacement cartridge. HP's printer packaging indicates whether introductory
cartridges are included with the printer.
WhatisISO?
ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards.

Actual yield will vary depending upon the amount of content on the page. Highly "dense" documents, such as the text document
below, may yield fewer pages than the ISO standard, while less dense ones such as the organization chart below would yield more
pages than the standard. Printing that uses primarily one color could cause lower yields for that color, and higher yields for colors not
heavily used. The yield you experience will depend upon the content that you print.
Some inkjet users print a few pages at a time, and hours, and sometimes days, pass between print jobs. With this kind of start/stop
printing, inkjet printers use some ink to keep print nozzles clear and ink flowing smoothly. This is critical to maintain the health of your
printer, and ensure that you continue to experience the same great print quality that your printer delivered when it was new. However,
it can cause your yields to be lower than if you printed the same content continuously.
Under the ISO 24711 testing guidelines, a standard set of five 8 1/2 x 11 pages is printed
continuously until the cartridge reaches end-of-life. For a variety of reasons, these test-
ing conditions may not reflect what you experience in every day use. ISO standard page
yields therefore should be used only as a starting point for comparison purposes, and not
to predict the actual yield you will get from your HP printer and cartridge. Actual yield
varies considerably based on the content of printed pages, frequency of printing, ink
used in printer set-up and other factors, as discussed below.
The five standard ISO pages shown to the right consist of a mix of text and graphics, and
a mix of black and color.
