Expression Premium ET
Expression Premium ET is Epson's photo branch of the EcoTank family — five-color supertank printers that refill from 512 ink bottles instead of cartridges. The 512 family pairs a 140 mL pigment black bottle (T512020, up to 8,000 pages) for documents with four 70 mL dye bottles — Photo Black (T512120), Cyan (T512220), Magenta (T512320) and Yellow (T512420) — for photographs, the colors rated at up to 5,000 pages each (ISO/IEC 24712). Find your model below and refill with Clever Supplies compatible 512 bottles, backed by a lifetime warranty.

Expression Premium ET Ink — The Five-Bottle 512 Family The Expression Premium ET-7700 and ET-7750 are photo printers first: a five-ink system in which a pigment black handles text and four dye inks handle images. That split is the whole point of the 512 family. The black bottle (T512020) is a big 140 mL pigment bottle rated up to 8,000 pages; Photo Black, Cyan, Magenta and Yellow are 70 mL dye bottles, the three colors rated up to 5,000 pages each on the ISO/IEC 24712 pattern with Epson's methodology. Epson does not publish a separate page yield for the Photo Black bottle, so we don't invent one.
One code warning that prevents the most common wrong order in this family: in the 512 series, T512120 is Photo Black — not black. The document black is T512020. The numbering runs against the pattern used by the 502 family, so read the full code before you order.
And keep the families apart: 512 bottles fit only the ET-7700 and ET-7750. The 502 and 522 bottles sold for other EcoTank models are keyed differently and will not seat in these printers. Clever Supplies compatible 512 bottles match the genuine fill volumes and keyed EcoFit fit, and carry our lifetime warranty with 1-year free returns.
