cartridge yield for monochrome

laser printer Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively-charged cylinder called a "drum" to ...

s, introduced in June 2004 and updated in 2017. Traditionally, printer manufacturers did not employ a standard, well-defined methodology for measuring toner cartridge yield. The most widely used description of cartridge capacity was "number of printed pages at 5% coverage", with final results depending on a number of factors. In contrast, ISO/IEC 19752 strives for a comprehensive and rigorous definition of the measurement process with the purpose of creating clear and objective criteria for comparison of cartridge yields. In particular, the standard provides a detailed definition and description of: * Test preparations and environmental conditions * Sample size (at least 3 printers with 3 cartridges each) * Paper type * Print mode * Test document (provided in PDF format) * Cartridge and printer source (''not'' supplied by manufacturer; purchased on the open market from at least three different sources) * Error and process handling * End-of-life criteria (for example, how many times the cartridges should be shaken)
