BS ISO/IEC 24711:2015 pdf download-Method for the determination of ink cartridge yield for colour inkjet printers and multi- function devices that contain printer components.
4.7? Test? files The test files are outlined and specified in ISO/IEC 24712. The test must be conducted using the most recent official electronic test files as the input. The most recent official file can be located at (http:// www.iso.org/jtc1/sc28). Failure to use the exact file specifications will invalidate test results. In addition to the test files a publicly available PDF reader will be used in conjunction with the printer driver to generate the printer input and send the files directly to the printer. The method used for connection between the host computer and the printer shall be recorded on the test report. For automated testing, a pre-generated print file can be used if the results are equivalent to direct printing methods. This will be recorded on the test report. The version of the test file, the printer driver version and the PDF reader version will be included in the test report. Before starting the test, a sample file set shall be printed to check the image and ensure the proper size. The proper size for each of the pages in the test suite is specified in ISO/IEC 24712. NOTE 1 There are often several PDF reader versions available; each version can have an impact on the yield results. It is recommended that the latest version of the chosen PDF reader be used for testing. To reduce test variability due to other programs, it is recommended that test file generation be conducted on a printer with a “clean” install of the Operating System (OS) with only the printer driver, PDF reader and any test control software installed. Testing has shown that old installed drivers from the same or different printers can affect the yield results. NOTE 2 To aid in counting and tracking pages, a header or footer can be added to the test page suite. Every attempt shall be made to reduce the size of this addition to minimize the effect on calculated yield. If this information is included in the test suite, it shall be documented in the test report.
