WorkForce ET-4750
Like its ET-3750 sibling, the WorkForce ET-4750 is a WorkForce EcoTank — despite "Expression" labels you may see elsewhere — and it shipped with two sets of 502 ink. Refills: 127 mL pigment black (up to 7,500 pages) and 70 mL dye colors (up to 6,000 each). Shop compatible Clever Supplies 502 bottles below.

ET-4750 Ink Bottles — The WorkForce 502 Page The ET-4750 tops the WorkForce ET-47xx pair and drinks the same ink as the ET-3750: the Epson 502 family. Black is T502120 (127 mL pigment ink, up to 7,500 pages); cyan, magenta and yellow are T502220 / T502320 / T502420 (70 mL dye ink, up to 6,000 pages per color; ISO/IEC 24712, Epson methodology).
Two naming traps surround this model. First, the series: ET-4750 = WorkForce. Second, the near-twin ET-4760 — that one is an EcoTank/Expression-shelf model but also 502, so its bottles are interchangeable with yours; the genuinely wrong buy is 522 (for ET-4700/ET-4800), which will not fit.
