The Brother LC3219XL BK Black Ink Cartridge for MFCJ6530DW/MFCJ6930DW High Capacity is an original Brother ink cartridge, with water-based ink specifically formulated for the brand's 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 of the cartridge before use, and has a built-in chip that allows the printer to monitor the ink level and warn in advance when it is running low. It is suitable for replacing the original ink cartridge as soon as the printer signals the need for refilling, maintaining print quality over time. This high-capacity black version has an estimated yield of approximately 3000 pages, much higher than the standard LC3217 versions compatible with the same equipment, and is suitable for Brother MFC-J6530DW and MFC-J6930DW A3 format multifunction printers. It is recommended for offices with very regular text printing that need to reduce the frequency of ink cartridge replacement.
