Yield Information -

Page Yield Information

INKS - 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".

Page yield data should be used as a starting point for comparison purposes, and not to predict the exact yield you will get from your printer and cartridge. Likewise, the declared yield is not intended to be the minimum number of pages that the cartridge will print. Rather, page yield data is meant to estimate the average yield expected from a particular cartridge when measured using the ISO test methodology in connection with a designated printer system. Individual cartridges can perform above and below this average due to variation in the cartridge manufacturing process. Additionally, actual yield varies considerably based on factors such as the content of printed pages, typical printer job size, the environmental conditions during operation and the amount of color printing relative to monochrome printing.

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.
