Page yield explained
In the product descriptions of our inkjet and toner cartridges we always mention the number of pages you can print with it. This way, dealers and users can easily compare our printer cartridges to those of other brands. But how is the page yield actually measured? And what method is used? Pelikan explains.
In the beginning..
For a long time there was no clear standard to determine the page yield of inkjet and toner cartridges. Some printer and cartridge manufacturers assumed an average of 5% coverage on an A4 sheet. They fully used up the cartridge and then counted the number of pages printed. The lack of further test criteria, however, meant that one is still comparing apples to oranges. Moreover, there were also manufacturers that used other methods, which led to even more confusion.
ISO standard for page yield
In June 2004 that all changed when an ISO standard to determine the number of pages printed with a black toner cartridge was published. This standard was embraced by all printer manufacturers and many producers of alternative toner cartridges. It has been THE standard in the market ever since. Later on, standards for color and inkjet cartridges were also published.
The ISO standards for page yield describe exactly how the tests should be conducted. For example, under what conditions (temperature, humidity, etc.), the size of paper used, the print quality settings, the size of the test (at least three printers with 3 different cartridges per printer), the test document that should be used, how to deal with error messages and even how often you should shake the cartridge when it is nearly empty. In addition, the printers and cartridges should be purchased on the open market from three different vendors. It is not allowed to buy directly from the supplier.
Pelikan stands for quality and transparency. Therefore, we alway test the print capacity of all inkjet and toner cartridges according to the ISO standards. This makes our products easily comparable to that of other brands. Moreover, it is a comprehensive and reliable test method, which is widely accepted. The way we run the ISO tests has been checked and approved by an independent institution – TÜV. Important when it comes to public procurement: Pelikan provide an ISO document for each article number, including a test report.
