1 Replacement ink bottle yields based on the ISO/IEC 24712 pattern with Epson’s methodology. Actual ink yields will vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink color. All ink colors are used for printing and printer maintenance, and all colors must be available for printing.

2 Savings comparison based on the purchase cost of replacement ink bottles and the cost of enough cartridges to achieve the total page yields of the bottles using the manufacturers’ online prices and yields for the highest-capacity cartridges for the best-selling, similarly featured consumer inkjet printers priced at $499 or less per NPD, July 2016. Actual savings will vary based on print tasks, print volumes and usage conditions.
