The modern Epson L3150 series inkjet MFPs allow you to ditch the cables and print documents or photos directly from your smartphone. This greatly simplifies working with texts, tickets, and educational materials, especially when you're away from a computer. Setting up a wireless connection requires careful attention, but it's fully automated thanks to the proprietary software.
Android device owners often encounter difficulties during initial synchronization, confusing the router and direct connection modes. In this article, we'll cover all the details of pairing, from preparing the equipment to fine-tuning the Epson iPrint app. You'll learn how to avoid common mistakes and ensure stable data transfer.
To successfully implement this plan, you'll need a stable home network and a charged device. It's important to understand the difference between connecting through a router and a direct connection, as the steps in each case differ. We'll cover both options so you can choose the one that best suits your situation.
Equipment preparation and compatibility testing
Before you begin setting up, make sure that your Epson printer The device is turned on and in standby mode without errors. There should be no low ink or paper jam warnings flashing on the display or indicators. Make sure the cartridges are installed correctly and the print head has been calibrated.
Your mobile device must be running Android 5.0 or higher. Older versions may not support the required security protocols or have access to the required file system permissions. Please ensure you have sufficient storage space on your phone to install additional software.
- 📱 Charge your smartphone to at least 50% to prevent it from turning off during the setup process.
- 📶 Find out the password for your Wi-Fi network if you plan to connect through a router.
- 🖨️ Make sure that the Epson L3150 MFP is located in an area with a strong signal reception.
If you're using a dual-band router, pay attention to the frequency. Some older printer models work better in the 2.4 GHz band, although the L3150 also supports 5 GHz. However, for initial setup, it's recommended to use the primary network your phone is already connected to.
⚠️ Attention: Make sure that Client Isolation is not enabled on your router, otherwise your phone will not see the printer on the local network, even if they are connected to the same Wi-Fi.
Resetting network settings on an Epson printer
If the device was previously used with a different router or the settings have been reset, you should reset the network settings. This will clear saved profiles and return the Wi-Fi module to a state ready for a new configuration. Ignoring this step often leads to IP address conflicts.
To perform a reset, locate the button marked with a wireless network icon on the control panel. Press and hold it together with the information button (the "i" icon) for a few seconds. The Wi-Fi and Wi-Fi Direct indicators will begin flashing alternately, indicating a successful reset.
☑️ Reset network settings
After rebooting the communication module network settings will be reset to factory defaults. The printer will automatically create a temporary access point for initial configuration. At this point, the model name with the "Direct" prefix may appear in the list of available networks on your phone screen.
It's important not to confuse this mode with the final setup. A reset is necessary for the printer to stop searching for the old router and begin transmitting a signal for a new pairing. Without this step, automatic setup via the app may not work correctly.
Installing the Epson iPrint app on Android
The official Epson iPrint app is the primary management tool. Available in the Google Play Market, it provides full access to all the MFP's functions. This interface not only prints but also scans documents directly to your phone's memory.
Download and install the app, granting it the necessary permissions to access files and geolocation. This last point is important, as in modern versions of Android, access to the list of Wi-Fi networks is only possible with GPS enabled. Without it, the app simply won't detect your printer.
| Function | Description | Requirement |
|---|---|---|
| Photo printing | Printing images from the gallery | Access to media |
| Scanning | Saving copies to PDF/JPG | Access to storage |
| Diagnostics | Checking nozzles and ink levels | Stable Wi-Fi |
| Software update | Printer firmware update | Battery charge > 50% |
The app's interface is intuitive, but it has its own quirks. The connection status is displayed at the top of the screen. If it says "No Printer" or "Not Selected," the connection is not established. Tap this area to start searching for available devices on the network.
Setting up a Wi-Fi Direct connection
Mode Wi-Fi Direct Allows you to create a direct connection between your phone and printer without using your home router. This is ideal if you need to quickly print a document when visiting someone or in an area without access to the main network. In this case, the printer acts as an access point.
To activate this mode, press the Wi-Fi button on the printer's control panel. The indicator light should turn green or stay on solid, depending on the firmware version. If the indicator light is blinking, it's searching or setting up. A name like "EPSON123456" will appear in the list of Wi-Fi networks on your phone screen.
Connect to this network. The default password is listed on the printed network information page, which can be accessed by pressing the information button on the MFP itself. This is usually a combination of numbers printed on a sticker or given to you when you first turn it on.
- 🔗 Open Wi-Fi settings on Android and select the printer's network.
- 🔑 Enter the password (often this is 8 digits printed on the case or receipt).
- ✅ Wait for the "Connected" message in the network status.
After successful pairing, return to the iPrint app. It should automatically detect the device. If it doesn't, use the "Add Printer" button and select search by IP address or name. In Direct mode, the IP address is typically in the 192.168.223.x range.
⚠️ Attention: When connecting via Wi-Fi Direct, your phone may lose internet access because it switches to the printer's network, which does not have access to the external network.
Connecting via a home router (Infrastructure Mode)
For permanent work in the office or at home, it is better to set up a connection through your main routerIn this case, both the phone and printer will be on the same local network, allowing you to print from either device and access the internet simultaneously. This method requires initial setup via USB or WPS.
The easiest way is to use WPS. If your router has a physical WPS button, press it. Then, within 2 minutes, press and hold the Wi-Fi button on the printer until the wireless network icon appears on the MFP screen. The devices will automatically exchange encryption keys.
What to do if the router does not support WPS?
If there's no WPS button, you can set it up using the Epson iPrint app. Select "Add Printer" -> "Wi-Fi Setup." The app will attempt to transfer saved Wi-Fi passwords to the printer. Bluetooth and location services must be enabled on your phone for this to work.
If automatic setup doesn't work, use the app-based setup method. Open iPrint, select Wi-Fi, and follow the on-screen instructions. Your phone will transfer network information (SSID and password) to the printer via a temporary direct connection.
Once successfully connected, the Wi-Fi indicator on the printer will remain solid. The status in the app will change to "Selected." You can now print documents as long as both devices are within range of the router.
Troubleshooting and diagnostics
Users often encounter a situation where the printer is visible on the network, but print jobs are not sent or freeze. This may be due to dynamic switching. IP addresses, assigned to the device by the router. In complex networks, it is recommended to assign the printer's IP address in the router settings.
Another common issue is incompatible security protocols. If your router is configured only for WPA3, but your printer supports WPA2, the connection may fail. In this case, try temporarily changing the security type in your router settings or creating a guest network with compatible settings.
- 🔄 Restart your router and printer to update DHCP leases.
- 📡 Check if your phone is using mobile data instead of Wi-Fi.
- 🛡️ Make sure your phone's antivirus software isn't blocking local connections.
If printing is slow or drops out, check your signal strength. Epson L3150 printers don't have the most powerful antenna, so the distance to the router shouldn't exceed 10-15 meters in an open area. Walls and household appliances can significantly weaken the signal.
⚠️ Attention: App and firmware interfaces are subject to update. If the steps in the app differ from those described, please check the official documentation on the manufacturer's website, as the operating logic may have been modified by the developer.
