Printheads are precise electronic components. Due to their nature, original printheads are strictly non-refundable and non-returnable once installed or loaded with ink. Please inspect the printhead carefully and test compatibility before installation. If you encounter any technical concerns, please contact us immediately for assistance.

Contact us as soon as possible and provide your order information together with clear photos or videos of the product, packaging and labels. We will review the details and advise on the next step.
