When the Inkthrift Keys are new, they should be reading Full out of the package, this is unusual behavior. But from what I’m reading, after removing and re-installing these new keys/capsules they will actually reset to 100%? Am I reading this correctly? To answer your question about the resetter, yes you can use a SF resetter on these chips for manual resetting. But you shouldn’t have too if you are installing a brand new Key into your printer. BUT if you are installing a new Capsule into an already used Key (chip holder) before the status monitor reads the cart as empty, then yes you will need to manually reset the Key/Chip.
