For example, if the ISO test methodology indicates that the individual yields of a given set of cartridges are for cyan, for magenta, and for yellow, the composite yield would be The Composite yield number helps simplify yield reporting. Page yield All of HP Canada.
For Inkjet printer yields see www. Page yield data should be used as a starting point for comparison purposes, and not to predict the exact yield you will get from your HP printer and cartridge. Likewise, the declared yield is not intended to be the minimum number of pages that the cartridge will print.
Rather, page yield data is meant to estimate the average yield oage from a particular tst when measured using the ISO test methodology in connection with a designated printer system.
LaserJet Page Yields
Individual cartridges can perform above and below this average due to variation in the cartridge manufacturing process. Additionally, actual yield varies considerably based on factors such as the content of printed pages, typical printer job size, the environmental conditions during operation and the amount of color printing relative to monochrome printing.
ISO provides different methodologies for testing color and monochrome printer yields. Some HP printers include an “introductory cartridge” in the printer box, which may print less than HP replacement cartridges.
HP’s printer packaging will indicate whether introductory cartridges are included with the printer. An example of the standard page shown is shown below.

The actual test page can be found at www. For more information about the declared page yield of cartridges sold for use with specific HP monochrome printers see www. The five standard pages shown below consist of a mix of text and graphics, and a mix of black and color.
HP adopted these standards for color printers that were introduced after the publication of the standard at the end of Products produced prior to this continue to use HP’s proprietary yield test method. The test is based on a standard suite of five pages color or a single page monochrome printed consecutively until the cartridge reaches end-of-life. A cartridge is determined to be at end-of-life when the test pages fade or, for some printers, when the printer automatically stops due to end-of-life detection.
To account for variations that may occur, a minimum of 3 cartridges of each cartridge type is tested in each of 3 printers. ISO is a network of the national standards institutes of countriesone member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates the system. ISO is a non-governmental organization that forms a bridge between the public and private sectors.
On the one hand, many of its member institutes are part of the governmental structure of their countries, or are mandated by their government.
On the other hand, other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations. Therefore, ISO enables stzndard consensus to be reached on solutions that meet both the requirements of business and the broader needs of society.
For more information on ISO see www. An individual yield for a given color cartridge is the individual calculated page yield of a given color cartridge as demonstrated by testing using the ISO methodology, based on a minimum of 9 cartridges tested to end of life.
A composite yieldsimply stated, is a weighted average of the individual yields as demonstrated by testing using the ISO methodology of the cyan, yellow and magenta cartridges.
HP publishes a 3-color composite page yield for LaserJet printer cartridges. The composite yield is based upon the ISO reporting methodology for color printers, which provides for a single average reporting yield for Cyan, Magenta and Yellow ink cartridges. Black is reported separately as an individual yield. Keep in mind that page yield is just one component of cost, and that factors such as quality, reliability, productivity, and efficiency affect cost as well.
Products that work reliably will ultimately save you time and money.
