actually I bought earlier from this supplier also my cartridge but I will seriously think about. After the blue was empty I swapped it out and there were no problems. a week later was yellow row at the. I swapped it out and it was not recognized by the printer. I therefore the next yellow opened and the same game. at first I thought as if they do not properly lock into the holder and not enough pressure on the sensor chip but the exercise was not so. the 2nd cartridge sat better after I made my printer then came the message unreadable cartridge.
