Not directly compatible ...

Cartridges well received, but not compatible with MFC-J6920DW my. When changing the black cartridge, the printer does not recognize the compatible cartridge. There is no point disconnecting then reconnecting: the problem is with the chip, here is the method does not throw these 20 cartridges in the recycling container: 1 retrieve the original Brother cartridge and gently remove the chip above the cartridge (small screwdriver to pry and great care not to gun down the PCB). 2 - remove the chip on the compatible cartridge. 3- replace the original chip. The original chip does not fit well into the slot of the compatible cartridge. The step from Keyed must go to the back of the cartridge and it is unnecessary to fix the chip with anything. Then the printer recognizes all good, launches the spring cleaning of printheads and can (finally) to continue working. At the same time, next time, I choose a laser.
