The EcoTank Pro ET-5800 is a 4-colour all-pigment printer — Epson's words — and its replacement ink is the 542 family: black (T542120, 127 mL) up to 7,500 pages, colour bottles (70 mL) up to 6,000 pages each. Clever Supplies compatible 542 pigment bottles are below, with lifetime warranty coverage.

ET-5800 Ink: Pigment Only — Epson's Warning, Word for Word The ET-5800's official page carries a sentence worth quoting exactly: "Printer Designed For Use With Pigment Inks Only. Use of Dye Inks May Cause Damage not covered by the Epson Limited Warranty." Its ink type is listed as DURABrite pigment ink, palette Cyan, Magenta, Yellow, Black — pigment in the colours, not just the black.
That is the practical meaning of the 542 family: the bottles on this page are pigment inks because the printer demands pigment inks. Dye-based EcoTank bottles (502/522 families) are not a cheaper substitute here; they are a warranty risk in a machine that was never built for them.
