Misplacement of the chip will trigger a wrong signal on the LCD screen. So please double confirm if the chip is firmly inserted before the final installation into the printer. If a wrong signal keeps reminding, please discharge the toner from the printer, readjust the chip’s position, and put it back later to dismiss the error.
