MichiganInksupply's compatible Brother LC51M Magenta ink cartridge is designed to be a drop in replacement for the original Brother LC51M ink cartridges. This is a compatible ink cartridge manufactured from new parts and was not manufactured by Brother. Our compatible LC51M ink cartridges are engineered to produce the same quality and quantity of prints that you would get with OEM (Original Equipment Manufacturer) at a fraction of the cost. The use of compatible replacement ink cartridges and supplies will not void your printer warranty.
Note: We do not recommend mixing OEM and compatible cartridges, as chip issues may result from not matching sets.
