LaserJet Page Yields
For all LaserJet printers and Multi Functional Products sold, HP publishes page yield data for the printer function of these devices.
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 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.
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.
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.
HP monochrome printer declared yield is determined using the ISO/IEC 19752 test methodology
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.
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 HP’s 5% coverage methodology.

HP color printer declared yield is determined using the ISO/IEC 19798 test methodology
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 HP’s proprietary yield test method.
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 factors including the content that you print and the manner in which you print.
