Expression Premium ET-7750
The Expression Premium ET-7750 is the wide-format member of the 512 family — the same five-color EcoTank photo system as the ET-7700, printing up to 11 x 17 inches. Its ink is identical: pigment black T512020 (140 mL, up to 8,000 pages), dye Photo Black T512120, and 70 mL dye cyan, magenta and yellow bottles rated up to 5,000 pages each. Compatible Clever Supplies 512 bottles are below.

ET-7750 Ink — Wide-Format Photos, Same 512 Bottles The ET-7750 stretches the ET-7700's five-ink photo system to 11 x 17 prints, but the refill shelf does not change: Epson's own support documentation lists 512 for both the Black and Photo Black positions on this model, with the same bottle sizes — the 140 mL pigment black (T512020, up to 8,000 pages) and 70 mL dye bottles for Photo Black (T512120), Cyan (T512220), Magenta (T512320) and Yellow (T512420), colors up to 5,000 pages each (ISO/IEC 24712, Epson methodology).
Large prints drink color faster than letter pages do, so ET-7750 owners tend to refill the dye positions more often than the document black. Singles are there for exactly that; the 5-bottle set resets all five tanks when a big project is coming.
If you run both an ET-7700 and an ET-7750, one shelf of 512 bottles covers both machines. What neither machine takes is 502 or 522 ink — different families, different keying. All Clever Supplies 512 bottles carry a lifetime warranty and 1-year free returns.
