Modern users rarely use computers to print documents, preferring to send files directly from their smartphones. Canon MG3140 — This is a popular budget MFP that, despite its age, handles basic tasks well if properly configured on a local network. Connecting the device to a router allows for printing without unnecessary wires and cables, which is especially convenient for apartments or small offices.
The setup process may seem complicated due to the lack of a display on the printer body, but it's quite feasible if you follow the steps. You'll need a stable signal. Wi-Fi, knowledge of the network password, and access to your phone. In this guide, we'll cover all the details, including using dedicated apps and direct connection modes, so you can start printing in minutes.
It is important to understand that wireless connection This requires some preliminary equipment preparation. The printer must be within a strong signal range, and the router must be functioning properly. If you're setting up Canon network equipment for the first time, follow each step carefully, as missing a single step can lead to communication errors between devices.
Equipment preparation and compatibility testing
Before you begin setting up, make sure that your Canon PIXMA MG3140 The printer is working properly and has consumables. The device must be plugged in and the power indicator light must be solid. Also, check that the cartridges are installed correctly and the protective tape is removed; otherwise, the printer will not enter ready-to-use mode.
The key is compatibility between your phone and router. Most modern smartphones operate in the 2.4 GHz and 5 GHz bands, but older printer models, such as MG3140, often only support the 2.4 GHz frequency. If your router only broadcasts on the 5 GHz band or uses WPA3 mode, the printer may not see the network.
⚠️ Note: If your router is broadcasting the same network (SSID) for both bands, try temporarily separating them in the router settings so that your phone connects to the 2.4 GHz band during setup.
To connect, you'll also need to know the exact name of your wireless network and its password. If you're using a guest network or corporate Wi-Fi with browser authentication, connecting the printer using the standard method won't work—you'll need a private network with a password.
Activating wireless mode on the printer
The first step is to put the printer itself into connection standby mode. On the front panel Canon MG3140 There's a button with an image of a smartphone or antenna. Pressing it initiates the network search or activates hotspot mode.
There are two main activation methods: via a button on the panel or a combination of buttons. In the first case, you need to press the button Wireless and hold it until the power indicator starts blinking. This indicates that the Wi-Fi module is activated.
- 📶 Press the wireless button once to check the current connection status.
- 🔄 Hold the button for a few seconds to reset the network settings to factory settings.
- 📱 Use the button to start Direct Connect mode.
- ⚙️ Combine presses with the Stop button to enter setup mode.
Once activated, the Wi-Fi indicator should blink, indicating the device is ready to pair. If the indicator is solid, the printer is already connected to a network and needs to be reset before reconfiguring.
Setup via WPS (the fastest method)
If your router supports the technology WPS (Wi-Fi Protected Setup) significantly simplifies the connection process. This method allows you to automatically transfer the network password, eliminating the need to manually enter it on a device without a screen.
First, find the WPS button on your router. It may be a physical button or a virtual one in the router's web interface. Press it and you'll be immediately connected to the printer.
Press the Wireless button on the printer -> Hold the Stop button (Red triangle) until the Alarm indicator flashes -> Release the Stop button -> Press the Wireless button again.After completing this sequence, the Wi-Fi indicator on the printer should blink rapidly, indicating it's searching for a network. Within 2 minutes, press the WPS button on the router. The devices will find each other and the connection will be established automatically.
| Indicator status | Meaning | Action |
|---|---|---|
| Blinks rarely | Network search | Wait for connection |
| It's on constantly | Successful connection | You can print |
| Blinks frequently | WPS error or search | Check your router |
| It doesn't burn. | Wi-Fi is off | Press the Wireless button |
This method doesn't work with all providers and router models. If a connection isn't established within 3 minutes, the indicators will return to their original state, and the procedure will need to be repeated.
☑️ Pre-WPS Check
Using the Canon PRINT Inkjet/SELPHY app
The most functional way to manage printing is to use the official application from the manufacturer. Canon PRINT Inkjet/SELPHY Available for Android and iOS, it allows you to not only print but also scan documents directly to your phone.
Download the app from Google Play or the App Store and launch it. When you first launch it, you'll be prompted to add a printer. Select the device registration option and follow the on-screen instructions. The app will automatically attempt to find the printer on your local network.
⚠️ Important: Make sure your phone is connected to the same Wi-Fi network you want to connect the printer to. If your phone is connected to mobile data (4G/5G), setup will fail.
If the automatic search doesn't yield any results, select manual adding. In this case, the app will ask you to confirm the model. MG3140 and may request that you enter the Wi-Fi network password again to transmit it to the printer.
Once successfully added, you'll see the "Ready to Print" status. Now you can select photos from your gallery, PDF documents, or web pages and print them. The app also lets you adjust paper and image quality settings.
What should I do if the app doesn't see the printer?
Make sure your phone's mobile data is disabled. iOS sometimes blocks local device searches if "Private Wi-Fi" is enabled for the network. Try disabling it in your phone's Wi-Fi settings.
Direct connection (Canon Direct Connect)
Model Canon MG3140 Supports Direct Connect mode, which allows the phone to connect directly to the printer without a router. This is convenient if the router is faulty or you're in a location without access to the main network.
To activate this mode, press and hold the wireless button on the printer until the power indicator flashes once, then release. A new connection with a name similar to "Canon_MG3140" will appear in the list of available Wi-Fi networks on your phone screen.
Connect to this network. The default password is usually listed in the instructions or on a sticker under the printer lid (often the last 8 characters of the MAC address or the word "canon"). Once connected, your phone will receive the printer's IP address, and you can send documents.
- 🔒 The connection is protected by a password, which is unique for each device.
- 📉 Data transfer speed may be lower than via a router.
- 🌐 The Internet on your phone will not work while a direct connection is active.
- 🔄 To exit the mode, turn off the printer or press the Wi-Fi button again.
This method is ideal for one-time printing of large volumes of photos or documents when you don't want to overload your main home network. However, for continuous use, it's better to set up a connection through a router.
Solving typical problems and errors
Even if you strictly follow the instructions, difficulties may arise. Often, the problem lies in the router's security settings. For example, if MAC address filtering is enabled, the printer will simply not be allowed onto the network, and its error indicator will flash endlessly.
Another common reason is incompatibility of encryption standards. Canon MG3140 It may not support the new WPA3 standards, requiring the router to switch to mixed mode (WPA2/WPA3) or pure WPA2. Also, make sure the network name (SSID) does not contain Cyrillic characters, as older drivers may not handle them correctly.
If the printer "sees" the network but won't connect, try temporarily disabling the "Hidden Network" (SSID) feature on your router. Hidden mode can be restored after a successful connection, but initial setup requires the network to be visible.
⚠️ Please note: Specifications and software are subject to update. If standard methods don't work, check your provider's documentation or the official Canon website for current network security requirements.
If you perform a software reset of the printer's network settings (press and hold the Wireless and Stop buttons simultaneously until the Alarm indicator flashes), the device will return to factory settings. This often helps if previous setup attempts have written erroneous data to the device's memory.
