Page yield is the approximate number of pages that can be printed with a printer cartridge. In 2004, the International Organization for Standardization collaborated with the International Electrotechnical Commission to publish yield standards for monochrome toner (ISO/IEC 19752), color inkjet (ISO/IEC 24711) and color toner cartridges (ISO/IEC 19798).

How is ISO page yield determined?
ISO page yield is determined by thorough testing, which differs slightly between monochrome and color cartridges.

Monochrome toner cartridge yield test
This test (ISO/IEC 19752) uses a standard test page with about 5 percent coverage. The test page is printed continuously until the cartridge is empty (indicated by an “out of ink” message from the printer or discoloration on the test page).

Color inkjet cartridge yield and color toner cartridge yield tests
These tests (ISO/IEC 24711 and 19798) use a standard set of five test pages — four typical customer pages and one diagnostic page-that are printed continuously until the cartridge is empty. The standard set contains a mixture of images and text in different quantities to achieve an average of 5 percent coverage per color per page (for an aggregate total of approximately 20 percent page coverage). Page yield tests are conducted in a controlled environment with a temperature of 23 ° C +/-2 ° C.

Number of cartridges tested
At minimum, three cartridge sets are tested on three different printers (for a total of nine cartridges tested). These cartridges have different manufacturing dates and locations.

How does ISO page yield differ from actual page yield?
Because customers are unlikely to replicate the precise conditions of the ISO test’s controlled environment, actual page yields will vary. Various different factors play a part that will determine that every cartridge that the customer uses will almost always yield different results.

Does compatible cartridges differ from Original OEM cartridges with regards to page yield?
When using Trink’s ISO9001 certified ink and toner cartridges, you are assured that the estimated page yields will not differ from what you would get from an Original OEM product.
