100 years of light fastness Brother ink cartridges are particularly suitable for printing documents that need to be archived over a longer period of time. If you use Brother BP-71 printing paper at the same time - which is optimally matched to the composition of the ink contained in the printer cartridge - we even guarantee lightfastness for a period of 100 years. 4 separate cartridges All Brother ink multifunction devices have separate ink cartridges for each color. Only the cartridge that has actually been used needs to be replaced. This means you protect the environment and your wallet. Blue Angel Tested devices certified according to RAL-UZ 171 are characterized by their energy-efficient and low-emission operation when using Brother ink cartridges.
