Photo yield varies by printer model. Quoted yields are extrapolated based on Epson original methodology from the print simulation of Test Patterns provided in ISO/IEC 24712. Quoted yields are NOT based on ISO/IEC 24711. Quoted yields may vary depending on the images that you are printing, the paper type that you are using, the frequency of your prints and environmental conditions such as temperature. During the initial printer setup, a certain amount of ink is used to fill the print head’s nozzles, therefore the yield of the initial bundled set can be lower¹
