One way of measuring across brands, for easy comparison For people to be able to compare page yields between different printers and manufacturers, there is one industry-wide testing methodology. Canon, HP, Epson, Lexmark and other industry leading manufacturers have worked closely with the International
Standards Organization (ISO) to establish this standard. It is called “ISO/IEC 24711“. What does the ISO standard specify? ISO/IEC 24711 outlines the following: - The test methodology that manufacturers should use to determine ink cartridge yields
- The way manufacturers should declare yield values from these test results
- The appropriate method of describing the yield of cartridge in documentation supplied to the consumer Test methodology The quoted page yields are based on an average of three printers of a kind, each continuously printing a standard ISO sample document (ISO/IEC 24712) until the ink runs out (‘end of life’). This is done three times per printer, using a new set of
cartridges each time. The ‘end of life’ is then determined when either of two phenomena occurs:
- Fade, caused by depletion of ink in the cartridge, or
- Automatic printing stop, caused by an Ink Out detection function. | Page 1
