Dear customer,if the head have any problem,you can do as the following step: 1) do what on this link : https://support.hp.com/us-en/document/c01944580 2) Follow these steps: "If you still have the printer with this problem bear in mind that YOU CAN USE IT WITHOUT "SETUP CARTRIDGES". According to HP, Setup Cartridges are used only for calibration, (most of the time) they have the same capacity as a standard pack, but the embedded as signal that marks them as special cartridges. If the printer was reset to a factory condition (most likely), it expects those cartridges but you can enter the Support Menu (hidden) and clear the bit that signals the printer to perform that calibration and it will resume working ar the alignment page. In short: (As always, do this at your risk) 1) Go to SUPPORT MENU (see video), 2) System Configuration Menu 3) Ink initialization status 4) Change from "Set" to "Clear"
