Will repairs be covered under warranty if I use non-HP ink in my Ink Tank 110?
No, repairs or service required as a result of filling the ink tanks improperly and/or using non-HP ink will not be covered under warranty. Additionally, the warranty does not cover printer or printhead failure due to damage from use of non-HP ink or an expired printhead. (Pages 3, 4)
