ET-5170 Ink Bottles — The 542 Lineup, Straight From Epson's Page Few printers state their ink spec as cleanly as the ET-5170: "Ink Yield ISO Pages: 542 — Black: 7500, Color: 6000," with a box of two 127 mL black bottles and one 70 mL bottle per color. The ink is DURABrite ET pigment in every position.
That box tells you how Epson expects this printer to live: black-heavy business volume. Budget your shelf the same way — black (T542120) turns over fastest; the pigment colors follow at their 6,000-page rating.
