The Epson Printer default password will be required while configuring or resetting the printer. Without it, it may become impossible to set the printer settings as when required. It is useful while troubleshooting too. Unless you configure your Epson printer, it won’t run properly. To elaborate, while configuring the printer, you need to open a web browser on an iPad or PC connected to the network. Then select Go after entering the printer's IP address. You will be taken to the next page to input your login information. This is where your password will come in handy as you will have to enter your username and password. Generally, the default password would be Epson. Post this, you will have to navigate to TCP/IP in the Configuration menu and complete the remaining settings.
