Please ensure that the voltage and current of the printer power supply are normal. It is recommended that you connect the printer directly to the wall outlet before starting the test. Do not connect the wiring board in series, and temporarily disconnect the printer from the computer. If it still won't open, it means that the printer has hardware failure. Please contact Epson Authorized Service Center to further test the printer.
