HAVE YOU EVER WONDERED HOW MANUFACTURERS WORK OUT PAGE YIELD?
What is Page Yield?
Page Yield is the term given to how many pages per cartridge a printer typically produces. This gives the consumer an idea of how many pages they can expect to print from their cartridge, giving them an average price per page.
Don’t Manufacturers use the 5% Rule?
Traditionally, manufacturers would conduct their own testing to determine page yield in-house typically using a 5% coverage on an A4 page. With the advancement of printer technologies, a formalised means of page yield testing was needed. The International Organisation for Standardisation (ISO) worked closely with the leading Manufacturers and in 2006, ISO approved new standards for ink and colour toner printer cartridge page yield measurements.
What Method is Used Now?
All printer manufacturers now use this method in a controlled environment, with a temperature range of between 21°C and 25°C:
- 3 test printers of the same series – allows for any machine variations
- 3 cartridge sets per printer
- Test page/s below continuously printed until end of life – end of life being determined by either print fade caused by depletion of ink/toner or automatic print stop caused by an ‘Out of Ink’ detection function
