ISO IEC 24711-2021 pdf Information technology — Office equipment — Method for the determination of ink cartridge yield for colour inkjet printers and multi- function devices that contain printer components

All image and print quality modifiers shall be at their factory preset configuration for the printer and default-installed condition for the driver. If auto media detection is available on the printer, it shall be disabled and media-type set to plain paper. This is to avoid inaccurate sensing of the media. If the printer and driver settings differ, then the driver defaults shall be used. Any user selectable ink conservation modes, (e.g. draft) shall be disabled during testing. For printers that default to duplex printing, the default shall be overridden and the printer shall be set to simplex for yield testing. To ensure that the test page suite is printed correctly, any page size modifiers such as “Fit to Page” and font substitution shall be turned off. The file shall be printed using the fonts embedded in the file and shall be printed on the page in a size corresponding to the dimensions in the test page suite standard (ISO/IEC 24712). Page placement modifiers such as page centring can be used to place the image properly on the page. To facilitate automated testing, the test page suite may be pre-generated using the printer driver. This is often accomplished using a print to file command. This method is only valid if it does not affect the measured yield. If a pre-generated file is used, it shall be noted on the test report. If the printer under test uses an internal PDF interpreter, it is ok to use it as long as the printer defaults are set to not substitute fonts. If the internal interpreter is used, this shall be noted on the report. The application software (for example, Adobe Acrobat Reader ), printer driver and printer can have page size modifier functions, such as Fit to Page. Make sure that all of these functions are disabled.
