EPSON 673 BLACK INK BOTTLE ORGINAL

Product Description

EPSON 673 BLACK INK BOTTLE

The Epson 673 Black Ink Bottle (Official SKU: C13T673100 / T6731) is a genuine, high-volume monochrome liquid refill bottle engineered explicitly for Epson’s premium line of 6-colour photo-centric EcoTank and InkTank storage systems. Filled with a highly refined dye-based formula rather than a standard text pigment, this ink is specialized to achieve deep, rich black tones, high contrast, smooth grayscale gradients, and uniform shadow details across glossy and matte photographic media surfaces.

Critical Refill Notice: Photo Series vs. Document Series Compatibility

Because the 673 series is composed of highly fluid, photographic-grade dye components, it should only be used in the specialized photo printers listed above. You must avoid filling standard 4-color document EcoTank systems (like the L130, L360, L3110, or L3210 series) with 673 fluids. Document printers feature very different printhead thermal settings and nozzle diameters meant for standard text inks; crossing these formulas can distort color lookup tables, leading to inaccurate color reproduction or pooling in the printhead lines.
