The Brother LC422XL BK Black Ink Cartridge (BROLC422LXBK) is an original Brother ink cartridge, with water-based ink specifically formulated for Brother inkjet printheads, guaranteeing true colors and crisp text in both documents and photos printed at home or in the office. It comes in a sealed package ready to install, requiring no shaking or preparation before use, and has a built-in chip that allows the printer to monitor the ink level and provide advance warning when it is running low. It is suitable for replacing the original cartridge as soon as the printer indicates a need for refilling, maintaining print quality over time. This high-capacity black version has an estimated yield of 3000 pages, significantly higher than the 550 pages of the standard LC422BK version, making it ideal for those who print text regularly and prefer to reduce the frequency of cartridge replacement.
