To check if an HP ink cartridge is genuine, look for a security label on the cartridge, scan the QR code on the label with your phone, and then go to HP's website  hp.com/go/ok to verify the serial number on the label; if the label appears tampered or the serial number doesn't validate, the cartridge is likely not genuine.

If you cannot capture QR codes with a smartphone, go to the HP Mobile Authentication website at the URL shown on new security labels hp.com/go/ok and enter the label's serial number to validate the label. A valid response indicates that the cartridge is safe for purchase.

Let me know what you find out.
