The CPP is based on the SRP and ISO Page Yield of T13K Large Ink Pack and T15K Cartridge. Cost Per Page (CPP) is computed by dividing the SRP by the ISO Page Yield.
Page Yields are based on the ISO/IEC 24711 and 24712 standard for inkjet products. The ISO/IEC 24711 and 24712 standard is widely recognized as the most reliable method to test inkjet printers under standard conditions.
Actual yields will be lower with higher density images, hot or dusty conditions, less frequent printing, or printing predominantly with one color.
All ink colors are used for printing and printer/all-in-one maintenance, and all colors have to be installed for printing.
For print quality, part of the ink from the included cartridges is used for printer startup and a variable amount of ink remains in the cartridges after the “replace cartridge” signal.
