Amazed that it worked. It took a few runs on a printer that had been clogged for over a year and finally, perfect nozzle check. Still won\'t quite unclog another machine, but well worth $30.

Good morning. I have two questions, if you´re so kind to help me. 1) The expiration date key. Does it mean once we get it, we have a period to use it? Or what the expiration date referenced to? 2) If the printer has a problem and we have to format it again, will the key information lost and we need a new one, or does it be able to be used again?. Many thanks ! Esther
