When you choose a LaserJet printer, make sure you consider your individual printing needs.
A composite yield, simply stated, is a weighted average of the pokemon rot gameboy color individual yields (as demonstrated by testing using the ISO methodology) of the cyan, yellow and x-elerated complete guide package magenta cartridges.These page yield standards will help the customers to make more informed purchase decisions by objectively and accurately evaluating print cartridge yields.The procedure for using these pages is detailed in ISO/IEC 19798.A small number of toner cartridges still being sold by HP provide page yield based upon HP's 5 coverage methodology.ISO provides different methodologies for testing colour and monochrome printer evious 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.
This A4 page is continuously printed until the cartridge reaches end of life.
This ensures that settings remain consistent across different test events, independent of platform or paper size.
Numerous factors affect yield measurement including the test document, print job size, print quality modes, end-of-life determination, sample size and environmental conditions.The ISO/IEC 19798:2007 is only intended for the measurement of colour toner cartridge yield.The elements that make the ISO standard more rigorous than other proposed methodologies are its explicit test procedures, including test-page definition, statistical sampling and methods, environmental controls, and defined end-of-life conditions.Products produced prior to this continue to use HP's proprietary yield test method.Under the ISO/IEC 19752 testing guidelines, a standard page is printed continuously until the cartridge reaches example of the standard page shown is shown below.Figure 2: ISO/IEC 19798 Standard Test Suite of 5 Pages.HP's printer packaging will indicate whether introductory cartridges are included with the printer.Note: For all products compatible with printers sold before June, 1999 the published yields are based on our previous yield measurement methodology.
