EcoTank ET-4800
The EcoTank ET-4800 is the office-ready member of the 522 family — scanner, copier, fax, ADF and Ethernet on Epson's own spec sheet — and its ink is the family standard: four 65 mL dye bottles, black (T522120) up to 4,500 pages, colors up to 7,500 pages each. Clever Supplies compatible 522 bottles are below, with lifetime warranty coverage.

ET-4800 Ink: Business Hardware, Home-Priced Bottles Epson's specification sheet for the ET-4800 (CPD-60630R4) states the refill spec in one line: 522 Black ink bottle (65 mL), yield 4,500; 522 color ink bottles (65 mL), yield 7,500 — ISO/IEC 24712 with Epson's methodology, dye ink in all four positions.
Office use leans black-heavy, and in this family that means the black bottle (4,500 pages) is the one you'll reorder most; the colors' higher 7,500-page rating works in your favor on mixed document work. The 4-bottle set keeps a spare of everything on the shelf, which is how most small offices run this printer.
One boundary, repeated because the model names invite the mistake: the ET-4800 is 522; the ET-4850 is 502. Their bottles are keyed differently and do not interchange. All Clever Supplies 522 bottles carry a lifetime warranty and 1-year free returns.
