Brother released mid of 2014 the cartridge series LC-121. Printers working with these cartridges have the printing engine MFC-J 470.
The cartridges Brother LC-121 are a varation of the recently built Brother cartridges. The inkjet cartridges have an external two part housing and an inner ink tank. As Brother is now going that way too, attached to the cartridges LC-121 there is a chip. This chip is involved in the ink level control management for the cartridges and identifies the cartridge towards the printer.
The cartridge code for LC-121 cartridges in the different global regions are:
LC-101 North / South / Central America
LC-131 Asia / Oceania
