Start with checking the power cord. It should be connected properly to the power outlet and the printer. Moreover, make sure that the power outlet is in working condition.
Now check the USB cable connecting the printer to the computer. If it is damaged or not working, replace it with a new one.
Now pay attention to the lights on the printer. If you see no lights, it means that the printer is not turned on. In this case, try unplugging and replugging the printer. Next, press the power button on the printer to turn it on. If it still doesn’t turn on, try connecting it to another plug.
