Multifunctional device The Epson Stylus SX420W remains a popular choice for home offices due to its reliability and affordable consumables. However, switching from a wired connection to a wireless network often presents difficulties for users, especially if the router has been replaced or security settings have been changed. Proper configuration allows you to print documents from laptops, smartphones, and tablets without the need for a physical USB connection.
In this article, we'll cover every step of establishing a connection between a printer and a router, paying special attention to the nuances of modern encryption protocols. You'll learn how to avoid common pitfalls related to frequency ranges and drivers, and get answers to complex technical questions. Wireless printing becomes accessible even to those who are not experts in network technologies if you follow a proven algorithm of actions.
Before you begin setup, make sure your network equipment is working properly and is transmitting an internet signal. Printer Epson SX420W supports the standard IEEE 802.11b/g/n, which provides sufficient speed for transferring documents and high-resolution photos. It's important to understand that connection stability directly depends on the signal quality at the location where the device is installed.
Preparatory stage and compatibility check
The first step is to analyze your current network infrastructure, as older printer models may not support the latest security standards implemented by router manufacturers by default. The Epson SX420W operates exclusively in the range 2.4 GHz and doesn't see the 5 GHz network, which is a common cause of device failure. If your router broadcasts a single network with combined frequencies (Smart Connect), you may need to separate them in the router settings or create a guest network for the 2.4 GHz band only.
You should also prepare the necessary authorization information in advance: the network name (SSID) and password. Pay attention to the case of letters and special characters, as printers are sensitive to even the slightest inconsistency. It is recommended to temporarily disable MAC address filtering on your router, if enabled, to prevent the new device from being blocked.
⚠️ Attention: The WPA3 security protocol, which is now being actively implemented in new routers, may be incompatible with this MFP. If the connection fails, try temporarily switching the router to mixed security mode (WPA2/WPA3) or WPA2-PSK (AES) only.
To successfully integrate the device into the local network, you will need:
- 📡 A working Wi-Fi router with DHCP enabled.
- 🔌 Stable power supply for the printer and router.
- 💻 A computer or smartphone for initial driver setup.
- 📄 Knowing the exact password for the wireless network.
WPS method: the fastest way to connect
Technology Wi-Fi Protected Setup (WPS) Allows you to set up a connection without entering a password, using either a physical button or a PIN code. This is the simplest option for users who don't want to navigate complex menus. On the case The Epson SX420W has a button marked with a network symbol or the inscription Wi-Fi, which activates the search mode.
The automatic pairing process is as follows:
- Press and hold the button
Wi-Fion the printer control panel for about 3 seconds until the network light starts blinking. - Press the button within 2 minutes WPS on your router.
- Wait until the Wi-Fi and LCD indicators stop flashing and remain on continuously.
If the lights are flashing alternately, this indicates a connection error. In this case, make sure the WPS function is enabled in the router's web interface, as some models are disabled by default for security reasons. It's also worth checking whether the printer is too far from the signal source.
☑️ Pre-WPS Check
Setting up via the printer control panel
If the automatic method doesn't work, you can use the device's built-in menu to manually select a network. This method is more reliable, as you can visually control the SSID selection process. On the screen The Epson SX420W displays a list of available networks, but it may be limited to the first few items due to the buffer memory capacity.
Algorithm of actions through the menu:
- 🖱️ Click the button
Home(Home) on the control panel. - 📡 Select an item
Wi-Fi SetuporSetting up Wi-Fi. - 🔍 Click
Wi-Fi Setup Wizard(Setup Wizard). - 📝 Select your network from the list and enter the password using the on-screen keyboard.
Entering a password can be tedious due to the small screen and limited number of buttons. Be careful when changing the case of letters and entering numbers. After confirming the information, the printer will attempt to obtain an IP address from the router. A successful connection is confirmed by the IP address being displayed on the screen and the network indicator glowing green.
What to do if the network is not on the list?
If your network is hidden (Hidden SSID), it won't appear in the general list. In this case, select "Manual Input" in the Wi-Fi menu and enter the network name (SSID) and security type manually.
Using the EpsonNet Install utility
For more detailed configuration and installation of drivers, it is recommended to use specialized software. EpsonNet InstallThis utility scans the network, finds the printer, and helps you configure it with the correct settings. You can download the latest version from the official support website by selecting your operating system.
The program not only allows you to connect the device but also change its network settings, such as assigning a static IP address, which is useful for print servers. During installation, select "Wireless Connection" and follow the wizard's prompts. The utility will automatically transfer the network settings from your computer to the printer.
⚠️ Attention: While the installer is running, your antivirus or Windows Firewall may block network device scanning. We recommend temporarily disabling protection or allowing the application to access your local network.
After successfully installing the software, check the device's status in the Print Task Manager. If the status is "Ready," the connection is established correctly. The utility will also prompt you to check for firmware updates, which may improve the stability of the Wi-Fi module.
Troubleshooting connection and driver issues
A common problem is when the computer doesn't see the printer, even though the LEDs are green. This may be due to the devices being on different subnets or client isolation being enabled on the router. Check that the first three octets of the IP address on the computer and printer match (e.g., 192.168.1.X).
For diagnostics, use the network status report print button. Network or the key combination specified in the instructions to print a data sheet. There you'll find the current IP address, subnet mask, and signal strength.
Compare the obtained data with the parameters of your network in the table below:
| Parameter | Value in the printer report | Meaning in the router | Status |
|---|---|---|---|
| IP Address | 192.168.1.15 | 192.168.1.1 (gateway) | The network matches |
| Mask | 255.255.255.0 | 255.255.255.0 | Norm |
| SSID | Home_WiFi | Home_WiFi | Matches |
| Signal | -65 dBm | - | Good |
If the values don't match, try rebooting the router and printer to renew the DHCP lease. In rare cases, resetting the printer's network settings to factory defaults via the menu may help. Network Reset.
Mobile printing and additional features
Once Wi-Fi is successfully set up, mobile printing options are available to you. Epson SX420W supports technology Epson iPrint, which allows you to send documents directly from your smartphone. Simply install the app on iOS or Android.
The app will automatically find your printer on your local network. You can scan documents directly to your phone, check ink levels, and order consumables. This transforms your old MFP into a modern network device.
The function is also available Wi-Fi Direct, which allows you to connect your phone directly to the printer without a router. This is convenient if you're visiting someone or working in an office with a secure corporate network. This mode is activated through the device's menu, after which the phone connects to the Wi-Fi network created by the printer itself.
Why won't my Epson SX420W printer connect to my new router?
Most likely, the new router uses the 5 GHz band or the WPA3 encryption protocol, which are not supported by this model. You need to configure the router to operate in 2.4 GHz mode and use WPA2-PSK (AES) encryption. Also, check that client isolation is not enabled.
How to find out the IP address of a printer without printing a report?
You can find the IP address in the router interface's DHCP Client List. Look for a device named "EPSON" or by the MAC address found on the sticker on the back of the device. The address is also displayed on the printer's LCD screen in the network status menu.
Can this printer be connected to a 5GHz network?
No, the model has a Wi-Fi module. Epson Stylus SX420W The router only physically supports the 2.4 GHz frequency. For it to work, it needs to be transmitting a signal in this range. If you have a dual-band router, make sure the 2.4 GHz network is active.
