The Epson 101 EcoTank Black Pigment Ink Bottle (T03V14A) is a high-performance printing solution engineered for precision and longevity. Containing 127ml of premium black pigment-based ink, this bottle is specifically designed for the Epson EcoTank L-series printers, including models such as the L4150, L4160, L6160, L6170, L6190, and the wide-format L14150. Unlike standard dye-based inks, the pigment technology used in the 101 series ensures that text remains exceptionally sharp and professional, with superior resistance to water, smudging, and fading, making it the ideal choice for business documents and archival purposes. One of the standout features of this ink solution is its incredible efficiency. A single 127ml bottle provides an impressive yield of up to 7,500 A4 pages, significantly reducing the cost per page and the frequency of refills. This makes it a cost-effective choice for both busy home offices and demanding enterprise environments. The bottle design incorporates Epson's innovative Key-Lock mechanism, which ensures that the tank can only be filled with the correct color, preventing accidental mixing and eliminating the mess typically associated with manual ink refills. The spill-free nozzle allows for a clean and seamless transfer of ink into the printer's integrated tank system. By choosing original Epson 101 ink, users ensure the continued reliability of their hardware while achieving consistent, high-quality results from the first page to the last. This ink is formulated to work in perfect harmony with Epson's Micro Piezo printhead technology, maintaining the health of the printer and delivering professional-grade output every time.
