The HP 976YC Black Contract PageWide Cartridge (L0S20YC) is a black ink cartridge for PageWide printing. HP identifies this exact part as an extra high-capacity contract cartridge, intended as a replacement supply for compatible PageWide printers.
Its black ink is suited to text and monochrome elements in everyday documents. The high-capacity format is useful in printing environments with regular workloads, helping reduce how often the cartridge needs replacement compared with a standard-capacity option. The manufacturer’s service manual lists L0S20YC under PageWide supplies and distinguishes it from the separate cyan, magenta and yellow contract cartridges.
