WorkForce ST-C Ink — 542 Pigment Bottles for Color Workgroups The ST-C5000, ST-C5500, ST-C8000 and ST-C8090 are high-volume color machines — Epson shipped them with multiple full ink sets in the box — and their replacement ink is the 542 family: DURABrite ET pigment in all four positions, black up to 7,500 pages and colors up to 6,000 pages each.
Don't let the ST name blur the families: the older WorkForce ST-2000, ST-3000 and ST-4000 are 502 printers with a pigment-black/dye-color split. The ST-C line is 542 — pigment in the colors too, different bottles, different keying. The badge's "C" is the tell: ST-C means the color supertanks on this page.
Our compatible 542 bottles match the family's volumes and keyed EcoFit fit, carry no chips, and are covered by a lifetime warranty with 1-year free returns.
