I purchased the set twice. With luck succeeded installed my first cartridge, although the Y-Partrone jumped at the slightest touch from the holder. Now was "M" empty (you must install before the cartridge. It is two separate parts, no single cartridge!) The second chip mounting settled While installing with firm pressure. But the printer has responded to this cartridge with the message "72" it would be "a problem with the cartridge before". Multiple and remove was unsuccessful. What good is a good color match when the holders are blundering?
