If HP Smart is unable to find your HP Smart Tank 670, 720, 750, 6000, 7000, or 7300 series printer or you are prompted for a Wi-Fi Direct password, perform a printer factory reset to place the printer into Wi-Fi setup mode. Once the printer is in Wi-Fi setup mode, use HP Smart to find and connect to the printer over your Wi-Fi network.
Restore an HP Smart Tank printer to factory defaults and set up the printer using the HP Smart app.
