Epson WF-4720 Printhead First locked

The Epson WF-4720 printhead labeled as "first locked" refers to an original, locked printhead specifically designed for use in Epson Workforce Pro WF-Series printers, including the WF-4720 model. This "first locked" designation means that the printhead is encoded or locked to work only with specific printer models and typically requires pairing with a corresponding ink supply or hardware setup. It is not an unlocked or generic printhead, so it is usually installed as the original or first replacement printhead for the WF-4720 printer.
