Only Brother knows best what is best for Brother printers and copiers.
Tip: Most ink cartridges now have a unique memory chip for correctly reading ink levels or other mechanical or electronic issues. This chip, and the this chip only, accurately interfaces with their specific device or printer and the PC with which it is operating. Most generic brands, many that sell for pennies on the dollar to product brands, either do not have a chip or one that works correctly with the product, or they have a correct chip that is often damaged when 'they' refill the used cartridge; such damage often results in false readouts/reports. So for most users, when ordering on the Internet, it is best to use recommended cartridges and equipment...for in the long run it saves time, frustration, and money.
