toner yield Toner Cartridge

ISO (International Organisation for Standardisation) is the worlds largest developer and publisher of International Standards.

HP publishes a 3-color composite page yield for LaserJet printer cartridges. The composite yield is based upon the ISO 19758 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.

For example, if the ISO test methodology indicates that the individual yields of a given set of cartridges are 480 for cyan, 500 for magenta, and 520 for yellow, the composite yield would be 499. The Composite yield number helps simplify yield reporting.

Under the ISO/IEC 19752 testing guidelines, a standard page is printed continuously until the cartridge reaches end-of-life. An example of the standard page shown is shown below. The actual test page can be found at

ISO/IEC 19752 methodology has been used by HP to test monochrome printer yields since its introduction in 2004. A small number of toner cartridges still being sold by HP provide page yield based upon HPs 5% coverage methodology. For more information about the declared page yield of cartridges sold for use with specific HP monochrome printers see

In recent years, LaserJet Printer and Multi Functional Product yield data has been calculated using standard ISO test methodologies. The specific ISO/IEC standard used depends upon whether the printer is a monochrome or color device. ISO provides different methodologies for testing color and monochrome printer yields. Previous to the introduction of the ISO/IEC yield methodologies, HP had its own proprietary yield test methodology based on 5% coverage which used a methodology similar in many ways to the ISO yield methodology.

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 de or, for some printers, when the printer automatically stops due to end-of-life detection.

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.

ISO is a network of the national standards institutes of 157 countries, one member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates the system.

To account for variations that may occur, a minimum of 3 cartridges of each cartridge type is tested in each of 3 printers.

A composite yield, simply stated, is a weighted average of the individual yields (as demonstrated by testing using the ISO methodology) of the cyan, yellow and magenta cartridges.

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 expected from a particular cartridge when measured using the ISO test methodology in connection with a designated printer system. Individual cartridges can perform above and below this average due to variation in the cartridge manucturing process. Additionally, actual yield varies considerably based on ctors 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. For more information seeHow toner is used.

Actual yield that a customer experiences can vary depending upon the printed content on the page. Highly dense documents, such as the text document below, may cause cartridges to yield fewer pages than the ISO standard, while less dense ones such as the organisation chart below will typically cause the cartridge to yield more pages than the standard. The yield you experience will depend upon a number of ctors including the content that you print and the manner in which you print.

For all LaserJet printers and Multi Functional Products sold, HP publishes page yield data for the printer function of these devices. For Inkjet printer yields see

Under the ISO/IEC 19798 testing guidelines, a standard set of five pages is printed continuously until the cartridge reaches end-of-life. 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 2006. Products produced prior to this continue to use HPs proprietary yield test method.

Keep in mind that page yield is just one component of cost, and that ctors such as quality, reliability, productivity and efficiency affect cost as well. Products that work reliably will ultimately save you time and money. When you choose a LaserJet printer, make sure you consider your individual printing needs. toner samsung scx 4200 inkjet ink price

ISO is a non-governmental organisation that forms a bridge between the public and private sectors. On 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.

Some HP printers include an introductory cartridge in the printer box, which may print less than HP replacement cartridges. HPs printer packaging will indicate whether introductory cartridges are included with the printer.

Therefore, ISO enables a 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

Black Cartridge: 16,500 pages / ColorCartridges: 21,000 pages

Although yields are calculated for individual cartridges, the yield test itself is conducted with all of the cartridges installed in the printer. LaserJet Printers are complex systems that may use more than one color cartridge when printing text and graphics. SeeHow toner is usedfor more detail.
