Have an Epson WF-7720 which is past warranty period but hasn't been used as forgot what the administrator password was set and forgotten. Can not hook up the network due to the password. Epson support was no help as warranty is up and only solution was to send it to a service center. Closest one is over 10 hours away. Looked for a reset button by ethernet and power supply but there is not one. Asked about factory reset and no help with that. Is there anyone who knows how to do this. I have called all the printer shops in my city and no one here knows how to reset it.
