Hi, It is understandable to be distressed if an ink cartridge leaks and potentially damages the printer. That is not a preferred outcome for our customers. Always be cautious when inserting a cartridge into the printer to avoid leaks. The cartridges have a vent near the label to prevent leaking. Ensure the vent is open before you install the cartridge. Leaking can happen with a damaged or defective cartridge. If the cartridge is defective, there is a possibility of an exchange or return. Contact HP through this link: https://www.hp.com/us-en/shop/cv/ReturnsandExchanges?id=page-return-exchange-policy/. Lastly, I recommend you correspond with our support team if the printer is also an HP product. There might be a way to fix it. Go to https://support.hp.com/us-en/contact-hp.
