The Epson 103 EcoTank yellow ink bottle (C13T00S44A) is a dye-based refill solution designed for high-volume everyday printing. With a volume of 65 ml, it helps you produce a large number of documents, contributing to a total color page yield of up to 7,500 pages when used as part of a full set. This makes it a practical choice for those who frequently print school assignments or travel documents and want to avoid the constant replacement of traditional cartridges. To make the refilling process as simple as possible, the bottle features a specialized key-lock design. This mechanism ensures that you can only insert the ink into the corresponding yellow tank, preventing accidental color mixing and keeping your workspace clean. It is compatible with a wide range of printers, including the L1110, L3100, L3110, L3150, L3160, L3200, L3250, L3260, and L3550 models. For safety, please note that the formula contains 1,2-benzisothiazol-3(2H)-one and 2,4,7,9-tetramethyldec-5-yne-4,7-diol.
