The Truth About "Page Yield" Numbers Nobody Talks About (how they're actually tested)

This video explains what the page yield number on printer ink and toner boxes actually means, how manufacturers test for it, and why the figure on the label rarely matches what people get from real-world printing. The video traces page yield testing back to inconsistent manufacturer claims before the 2000s and explains how an international standards committee created uniform testing rules for laser, LED, and inkjet cartridges. It walks through the exact testing method, including the low page coverage used in lab conditions, then covers independent research showing cartridges are often discarded with usable ink still inside. The video also breaks down the real cost of ink and toner per page and per ounce, and closes with a rundown of major lawsuits and settlements tied to page yield and cartridge design across the printer industry. What's covered in this video: Defines page yield as a standardized comparison figure rather than a guaranteed page count, and explains why manufacturer testing was inconsistent before formal standards existed. Covers the formation of an international technical committee in 1989 and the rollout of page yield standards: black-and-white laser and LED toner rules in June 2004 (updated 2017 and November 2025), and color laser toner and inkjet rules both approved in December 2006. Details the official test method, including five standardized test pages, a minimum of nine cartridges tested across at least three printers, controlled room temperature near 23°C, plain paper, and default settings. Explains why the roughly five percent page coverage used in testing, about half a page of plain 12-point Arial text, differs from typical printing with images, charts, and logos, noting color laser testing uses closer to twenty percent total coverage. Cites PCWorld Test Center findings that cartridges from Canon, Epson, and Kodak were flagged as empty while still holding as much as forty percent unused black ink. References Consumer Reports' 2013 finding that internal printer cleaning cycles can waste fifty percent or more of a printer's ink, adding up to one hundred dollars a year, alongside a 2007 Epson-funded TÜV Rheinland study estimating sixty percent of inkjet ink goes unused. Compares per-page costs across print technologies, with inkjet running roughly five to ten cents per page in black and white and laser running two to five cents. Covers Consumer Reports' calculation that ink can cost up to ninety-five dollars an ounce, and a UK Which? survey finding official ink priced up to two hundred eighty-six percent higher than third-party alternatives. Addresses the claim that ink costs more than human blood, tracing it to mid-2000s marketing blog posts rather than a scientific comparison. Explains why starter cartridges bundled with new printers hold only a fraction of a standard replacement's capacity due to ink used in priming the printer's delivery system. Discusses the 2017 Supreme Court case Impression Products v. Lexmark and its role in allowing the remanufactured and refilled cartridge industry to operate legally. Summarizes Epson's 2006 class action settlement worth up to nine hundred million dollars, HP's Dynamic Security litigation and settlements in the US, Italy, Europe, and Australia, and Epic Office Solutions' lawsuit alleging Epson overstated business printer yields. Ends with practical guidance on treating page yield as a comparison tool, budgeting for early starter cartridge replacement, and calculating true cost per page independently.
