Return Program ink cartridges are designed for use with Lexmark S315, S415, S515, Pro715, and Pro915. Combo pack includes cartridges in cyan, magenta and yellow. This printhead technology creates sharp results and brilliant prints every time. Precise, consistent drop placement creates vibrant documents with sharp, clear text and vivid images. Fast-drying inks create smooth, uniform colors and help ensure smear-resistant, two-sided printing. Return Program Cartridges are sold at a discount, versus the prices of regular cartridges, in exchange for the customer's agreement to use the cartridge only once and return it only to Lexmark for remanufacturing or recycling. Each cartridge yields approximately 200 pages.
