EcoTank Photo ET-8550
The EcoTank Photo ET-8550 takes the six-color 552 system up to 13 x 19 inches. Its ink is identical to the ET-8500's: pigment Black (T552020), dye Photo Black (T552120), Cyan, Magenta, Yellow and Gray (T552520), 70 mL per bottle. Compatible Clever Supplies 552 bottles are below — same keyed fit, lifetime warranty.

ET-8550 Ink — Wide-Format Photos, the Full 552 Set The ET-8550's official page lists its Ink Yield Information exactly as its A4 sibling's: Black 6,700 / Photo Black 7,300 / colors 6,200 / Gray 46,600 (ISO/IEC 24712, Epson methodology; photo yields per ISO/IEC 29103 are significantly lower, per Epson's footnote). The wide format changes consumption, not the shelf: big prints drink the dye colors faster, which is why singles outsell sets on this model — you refill the tank that's low.
Gray deserves its line on a wide-format page: at 13 x 19, banding in a black-and-white gradient is impossible to hide, and the Gray bottle exists precisely to smooth those transitions. Its 46,600-page document-pattern rating is Epson's official figure; on photo paper it will, like every bottle here, deliver far fewer pages — plan by tank level, not by the document number.
If you run both Photo models, one shelf of 552 covers both. Every Clever Supplies 552 bottle carries a lifetime warranty and 1-year free returns.
