The Epson C13T03P14A, also known as the No. 110 EcoTank Black XL, is a high-capacity original pigment-based ink bottle engineered specifically for the Epson EcoTank M-series monochrome printer range. This specialized ink formulation is designed to deliver professional-grade results, producing exceptionally sharp black text that is resistant to water, smudging, and highlighter bleed. Because it uses pigment-based technology, the prints are highly durable and fade-resistant over time, making it the ideal choice for business documents, archival records, and high-volume office printing. The XL high-capacity bottle contains between 120ml and 140ml of ink, providing a substantial print resource of up to 6,000 A4 pages at a standard 5 percent coverage. This high yield ensures an incredibly low cost per page, significantly reducing the total cost of ownership for busy workgroups. The bottle design features an innovative Key-Lock mechanism, which is a physical safety feature that ensures the bottle only fits the correct color tank and prevents accidental spills or leaks during the refilling process. This ink is exclusively compatible with the Epson EcoTank black-and-white printer series, including the M1000 series models such as the M1100, M1120, M1140, M1170, and M1180, the M2000 series including the M2110, M2120, M2140, and M2170, as well as the M3000 series models M3140, M3170, and M3180. By using genuine Epson 110 ink, users maintain the integrity of their printer's warranty and ensure consistent performance and reliability for all monochrome printing tasks. The design of the EcoTank system allows for easy, mess-free replenishment, making it a sustainable and efficient solution for modern office environments requiring high-speed, high-quality black and white output.
