Switching to wireless printing for owners of the L-series MFPs is not just a convenience, but a necessity in a modern office or home. Model Epson L850 Originally designed as a multifunctional device with built-in Wi-Fi, initial setup often presents difficulties for users accustomed to cable connections. Proper network configuration allows printing from any device within range of the router, without being tied to a desktop PC.
The communication module activation process requires careful attention, as errors in entering the password or selecting the operating mode can result in the device being "lost" in the system. Unlike simpler models, it's important to distinguish between infrastructure mode and direct connection. Connection stability directly depends on the signal quality and the correctness of the entered security settings for your local network.
In this article, we'll cover every detail of the process, from equipment preparation to fine-tuning IP addressing. You'll learn how to avoid the common mistakes that 80% of users encounter when first starting out. Following the steps carefully will guarantee a successful outcome, even for beginners.
Equipment preparation and requirements verification
Before you begin programming, you need to make sure the hardware is physically ready for use. Make sure that Epson L850 Plugged in and ready (the indicator is green and not blinking). It's crucial that the device is within range of your router's signal; walls and appliances can significantly weaken radio waves.
You'll need to know your wireless network name (SSID) and password to access it. If you haven't changed your router settings yourself, this information is often found on a sticker on the bottom of the device. For computers running Windows or macOS You must download the driver installation package from the manufacturer's official website in advance, as the basic OS drivers may not contain full functionality for working over a network.
⚠️ Important: Make sure your router is broadcasting in the 2.4 GHz band. Some older printer models may not recognize networks that operate exclusively in the 5 GHz band or may require compatibility mode to be enabled.
Check the CISS tanks for ink. While this doesn't directly affect your Wi-Fi connection, the unit may enter maintenance mode when ink levels are low, preventing access to the network settings menu. It's also recommended to remove all transport belts and locks if the unit has just been unpacked.
Resetting the printer's network settings
If the device was previously used on a different network or there were unsuccessful setup attempts, the best solution is a full reset. This will clear the memory of old profiles and return the network module to its factory default settings. To do this, press the "Stop/Reset" button on the control panel and hold it together with the power button for a few seconds until the indicators flash.
An alternative method is available through the device's menu. Press the "Menu" button, go to "Wi-Fi Settings," and select "Reset Network Settings." Confirm by pressing "OK." After the device reboots, the Wi-Fi indicator should begin rapidly blinking green, indicating it's ready to search for a network.
- 🔌 Disconnect the USB cable from the computer if it was connected.
- 📡 Make sure the Wi-Fi indicator on the MFP panel is blinking.
- 📱 Prepare your Wi-Fi password in text format for easy copying.
- 💻 Close all printing programs on your computer.
After the reset, the device will automatically enter connection standby mode. In this state, it will not appear in the operating system's list of available printers until the pairing process is complete. Do not attempt to search for it in the device list immediately, as this may result in an installation error.
Setup via WPS (Wi-Fi Protected Setup)
The fastest way to connect Epson L850 With a router, use WPS technology. This method eliminates the need to manually enter a password and select a network from a list. Make sure your router supports this feature (the WPS button is usually located on the router). Press the WPS button on the router, then the same button on the printer's control panel.
The device will automatically detect the network and pair. The Wi-Fi indicator on the printer should turn green and stop blinking, indicating a successful connection. If the indicator continues blinking or turns orange, the connection is not established and you will need to repeat the process or use the manual method.
What to do if WPS doesn't work?
The WPS function may be disabled in your router settings or not supported by your ISP. Connections may also fail if the signal is too weak or if corporate security is in use.
Using WPS is especially convenient if you don't know the network password or if it contains complex special characters that are difficult to enter on the printer's small keyboard. However, this method only works if the router and printer are in close proximity during setup.
Manual setup via the installation wizard
If the automatic methods don't work, you'll need to use the manual setup wizard. Run the previously downloaded driver installation file on your computer. In the connection type menu, select "Wireless" or "Wi-Fi." The wizard will prompt you to select a setup method: "Automatic" or "Manual."
If you select manual mode, the program will ask you to select your network from the list of available ones. Find your SSID in the list and click "Next." In the window that appears, enter your Wi-Fi password. Be careful with capitalization. After entering the information, the program will transfer the settings to the printer via a temporary USB connection or a direct connection.
| Parameter | Meaning / Action | Note |
|---|---|---|
| SSID (Network Name) | Select from the list | Do not rename manually |
| Security type | WPA2-PSK (AES) | Standard for home networks |
| Password | Enter manually | Case sensitive |
| IP mode | Auto (DHCP) | Recommended for home use |
During the installation process, the program may ask you to temporarily connect USB cableThis is necessary to transfer network profiles to the device. Once the data transfer is successful, the cable can be disconnected. The computer and printer are now on the same network and ready to exchange data.
☑️ Connection check
Setting up Epson Wi-Fi Direct
Technology Wi-Fi Direct Allows you to connect mobile devices directly to the printer without using a router. This is ideal for printing photos from your phone when visiting someone or in an office where network access is limited. To activate this mode, press the "Wi-Fi" button on the device's panel and select "Wi-Fi Direct" from the menu.
A signal with a name containing the printer model will appear in the list of available networks on the smartphone screen (for example, DIRECT-XX-EPSON L850). Connect to this network by entering the password displayed on the printer screen or printed in the configuration report. Once connected, you can send documents through the app. Epson iPrint.
- 📲 Open Wi-Fi settings on your smartphone.
- 🔍 Find a network that starts with DIRECT-.
- 🔑 Enter the password shown on the MFP screen.
- 🖨️ Start printing through the app.
It's important to understand that when using Wi-Fi Direct, your phone may lose internet access if it doesn't support two Wi-Fi networks simultaneously. In this case, you'll need to use mobile data (4G/5G) to access the global network.
IP address check and diagnostics
After a successful connection, it's extremely helpful to know the IP address assigned to the printer by the router. This will be needed to install drivers on other computers or to access the device's web interface. Print a network status report by holding down the "Stop" and "Wi-Fi" buttons simultaneously, or through the device's menu.
In the report, find the line “IP Address”. If the address starts with 192.168. or 10., then the device received the address correctly. If you see an address like 169.254.x.x, this indicates a DHCP error, and the printer hasn't received an address from the router. In this case, you need to reboot the router and repeat the setup procedure.
⚠️ Note: The printer menu interface and item layout may vary slightly depending on the firmware version. If you don't see an item, please consult the official documentation for your specific device version.
To diagnose connection problems, you can use the utility Epson Net Config, which allows you to manage the printer's network settings from your computer. It displays signal strength, encryption type, and allows you to manually enter the IP address if automatic sharing isn't working reliably.
