Brother LC71M Standard-Yield Magenta Ink Cartridge
Overview
The Brother LC71M is a standard-yield magenta ink cartridge for Brother inkjet printers running LC-series cartridge architecture. Rated for approximately 300 pages per cartridge, it addresses routine document and photo workflows in small office and workgroup environments where magenta replenishment needs to happen predictably without oversizing to high-yield stock. The LC71M installs directly into the magenta slot with no additional configuration—insert, remove the air vent plug per the instruction sheet, and print.
Compatibility
The LC71M works with Brother inkjet printers equipped to accept LC-series cartridges. Verify your printer model supports this cartridge format before ordering. The cartridge seats directly into the magenta ink slot without adapters or firmware changes. Page yield varies based on print coverage, ink density settings, and document type—300 pages is nominal for mixed document/photo use.
Installation Notes
Before installing the LC71M, remove the color air vent plug from the cartridge. Insert the cartridge into the magenta slot until the door clip contacts the sensor—this confirms proper seating. If refilling a refillable cartridge variant, remove the fill plug, inject approximately 80 ml of compatible ink into the fill hole upright, reinsert the fill plug, then remove the air vent plug before reinstalling. Do not force the cartridge or overfill the refillable chamber.
