I've replaced my Brother printer and the ink cartridges are proprietory so now I have a perfectly good set of ink cartridges (all colours - 2 black, 2 magenta, 1 Caen, 2 yellow) that don't fit my new printer. Three of them are full, all have some ink but they're cheap to refill once you have the cartridges. That's why I had an extra set. If you own an older Brother printer, you've already figured out that the cost of new cartridges is more than the price of a new printer. Refilling is a far more efficient way to do it. That's why I had extra cartridges. If you can use them, give me a call. Way cheaper than buying new .
