2, pay attention to grounding measures, when using the printer, choose the right power supply, and pay attention to its grounding protection measures. Please unplug the printer when you don't use it for a long time. In addition, if it is a thunderstorm, pay attention to unplug the power supply to avoid lightning damage to the printer.
