Expression Premium ET-7700
The Epson Expression Premium ET-7700 is a five-color EcoTank photo all-in-one that shipped with two full sets of 512 bottles — two 140 mL blacks and two 70 mL bottles of every other color. Refills stay in the 512 family: black (T512020) up to 8,000 pages, cyan, magenta and yellow up to 5,000 pages each, plus the dye Photo Black bottle (T512120) that does the photo heavy lifting. Clever Supplies compatible 512 bottles below are keyed for the ET-7700's five tanks.

ET-7700 Ink: Five Bottles, Two Jobs The ET-7700 prints documents and photographs from two different ink toolkits sharing one chassis. The black position (T512020) is pigment ink in the family's big 140 mL bottle — up to 8,000 pages of sharp, water-resistant text. The photo side is dye: Photo Black (T512120) for shadow depth and glossy blacks, and Cyan (T512220), Magenta (T512320) and Yellow (T512420) at 70 mL and up to 5,000 pages each (ISO/IEC 24712, Epson methodology). Epson publishes no separate yield figure for Photo Black, so none is claimed here.
Code discipline matters on this printer. T512020 is the pigment document black; T512120 is Photo Black. Ordering "120" out of 502-family habit buys you a photo black when you needed document black — the bottles are keyed per position, so the mistake shows up at refill time.
Order single bottles as positions run low, or the 5-bottle set to reset the whole system. Every Clever Supplies 512 bottle carries a lifetime warranty and 1-year free returns.
