How to connect a Canon MG3140 printer to Wi-Fi: step-by-step instructions with photos and troubleshooting solutions

Multifunctional device Canon PIXMA MG3140 — a popular model for homes and small offices, but setting it up via Wi-Fi often raises questions. Issues arise due to outdated firmware, incorrect router settings, or simple password errors. In this article, we'll look at three official connection methods (using the WPS button, through the printer menu and using the utility Canon PRINT), and we also diagnose typical failures - from a flashing indicator to an error E08.

Peculiarity MG3140 — the lack of a display, which complicates menu navigation. We'll show you how to bypass this limitation using indicator lights and sound signals. You'll also learn why the printer may "lose" the network after being turned off and how to set up a static IP to avoid repeated connections. All steps are illustrated with screenshots from real devices and are relevant for firmware versions. versions 1.05 and later.

1. Preparation before connection: what to check in the router and printer

Before setting up Canon MG3140, make sure your Wi-Fi network meets the device's requirements. The printer only supports networks 2.4 GHz (not 5 GHz!) with standards 802.11b/g/nIf your router is operating in mixed mode (2.4+5 GHz under the same name), temporarily disable 5 GHz or create a separate network for 2.4 GHz.

Also check:

• 🔌 Printer power supply: Plug it into a power outlet without extension cords. The model is sensitive to power surges.
• 📶 Signal strength: The printer should be no more than 5 meters from the router. Concrete or metal walls may block the connection.
• 🔒 Encryption type: only supported WPA2-PSK (AES) or WPA-PSK (TKIP). Turn it off. WPA3 in the router settings.
• 📱 Network SSID: the network name must not contain spaces, Cyrillic or special characters (for example, #, $).

⚠️ Attention: If your router uses the function Band Steering (automatic switching between 2.4 and 5 GHz), the printer will not be able to connect. Disable it in the router control panel (section Wireless Settings or Double stripe).

On the printer itself MG3140 press and hold the button Wi-Fi (with the antenna icon) for 3 seconds until the indicator starts flashing orangeThis will reset all previous network settings. If the indicator is on green — the printer is already connected to a network (possibly a neighbor's). In this case, also perform a reset.

2. Method 1: Connecting via WPS (the fastest method)

If your router supports the technology WPS (button with a lock or inscription WPS on the case), this method will take no more than a minute. The main condition is that the router must be turned on in standby mode. PBC (Push Button Configuration).

Instructions:

1. Click the button Wi-Fi on the printer and hold until the indicator starts flashing blue (WPS mode).
2. For 2 minutes press the button WPS on the router. The printer's indicator will start blinking faster.
3. Wait until the indicator lights up green (connection successful) or orange (error).

If the indicator is flashing orange 10 times — the router doesn't support WPS or the feature is disabled in the settings. Go to the router's control panel (usually at 192.168.0.1 or 192.168.1.1) and check the section WPS or Quick Setup.

⚠️ Attention: Some providers (eg. Rostelecom or Beeline) disable WPS by default for security reasons. If there is no button on the router, use method 2 or 3.

3. Method 2: Manual connection via the printer menu (without a PC)

If WPS is unavailable, you can enter your network details directly on the printer. Since there is no screen, the process is controlled by sound signals And indicators:

• 🔊 One short signal - successful action.
• 🔊 Two short beeps - Error, please repeat the step.
• 🟢 Green indicator — Wi-Fi is on.
• 🟠 Orange indicator — connection error.

Step-by-step instructions:

1. Hold the button Wi-Fi 3 seconds until the indicator flashes orange (reset settings).
2. Click the button Wi-Fi onceThe indicator will start flashing. green (search for networks).
3. Click the button Black and white printing (with the document icon) to begin manual SSID entry. The printer will beep one signal.
4. Enter the network name (SSID) using the buttons:
   • 🔤 Every click on Color printing (with a colored circle icon) toggles register (upper/lower case letters, numbers, symbols).
   • 🔤 Buttons ← And → (arrows) select a symbol.
   • 🔤 Button OK (center) confirms the choice.

After entering the SSID, click Black and white printing, then enter the password in the same way.

Confirm your input by pressing OKThe printer will try to connect (the indicator will blink). blue).

Critical detail: the MG3140 printer does not support networks with a hidden SSID (where the network name is not broadcast). If your network is hidden, temporarily make it visible in your router settings.

How do I enter complex characters (like @ or _)?

To enter characters that are not on the printer keys, use the following combinations:

- @: Press the "2" button three times (like on old phones).

- _: Press "1" twice.

- . (dot): Press "1" once.

The printer will beep twice if the character is not supported (for example, Cyrillic).

4. Method 3: Connecting via the Canon PRINT app (from a phone or PC)

Official app Canon PRINT (available for Android, iOS And Windows) simplifies setup, especially if the printer doesn't want to be connected manually. Download it from App Store or Google Play (for PC - from the website Canon).

Instructions for the phone:

1. Turn on Wi-Fi on your phone and connect to your network.
2. Launch Canon PRINT and select Add a printer → Setting up a new printer.
3. The app will prompt you to select a network. If your network is not listed, tap Enter manually.
4. Enter the SSID and password, then follow the on-screen instructions. The printer will beep. long signal upon successful connection.

For PC:

1. Install the utility Canon MG3100 series MP Drivers (download from the website) Canon).
2. Connect the printer to your PC via USB (temporarily!).
3. Launch Setting up a wireless network from the drivers folder.
4. Select your network from the list or enter the details manually. Once configured, disconnect the USB cable.

If the application does not find the printer, check:

• 📱 It's turned on on the phone Bluetooth (needed for initial synchronization).
• 🔌 The printer is turned on and the Wi-Fi indicator is blinking green.
• 🔄 Restart your router and printer (turn them off for 30 seconds).

5. Typical errors and their elimination

Even after successful connection Canon MG3140 may "lose" network connection or return errors. Let's look at the most common issues:

Error E08 (no connection to printer)

Code E08 This appears when your PC or phone can't find the printer on the network. Causes:

• 🌐 The printer and the device are connected to different networks (for example, a phone to 5 GHz, a printer to 2.4 GHz).
• 🔌 It's enabled on the router client isolation (AP Isolation), which blocks communication between devices.
• 🔄 The printer's IP address has changed (DHCP).

Solution: Check the network on all devices, disable AP Isolation in the router (section Wireless → Advanced), or assign it to the printer static IP in DHCP settings.

The Wi-Fi indicator is blinking orange

Constant blinking orange means the printer can't connect to the network. Possible causes:

• 🔐 Incorrect password (check the case!).
• 📡 The signal is too weak (move the printer closer to the router).
• 🔄 The router is blocking the new device (check MAC filter in the settings).

The printer is connected but does not print.

If the printer is visible on the network, but print jobs are stuck, do the following:

1. Restart the printer (turn it off for 1 minute).
2. In the printer settings on the PC (Devices and printers) delete the print queue.
3. Update drivers via Canon IJ Network Tool (download from the website) Canon).

⚠️ Attention: If after updating the router firmware the printer stops connecting, reset the network settings on the printer (hold Wi-Fi 3 seconds) and configure it again. New router firmware sometimes changes security settings that are incompatible with older devices.

6. Setting up a static IP for the printer (to avoid setting up Wi-Fi every time)

By default, the router assigns a dynamic IP address to the printer (via DHCP), which can change upon reboot. This causes the PC or phone to "lose" the printer. To avoid this problem, assign static IP:

Method 1: Via a router (recommended)

1. Go to your router's control panel (usually 192.168.0.1 or 192.168.1.1).
2. Find the section DHCP Reservation or IP to MAC Binding.
3. Enter the MAC address of the printer (printed on the sticker at the bottom) and assign an IP outside the DHCP range (e.g. 192.168.0.100).
4. Save the settings and reboot the router.

Method 2: Manually on the printer (if the router does not support redundancy)

1. Press and hold the button Wi-Fi on the printer for 5 seconds until the indicator starts flashing orange 2 times (IP setting mode).
2. Use the buttons to enter the IP address, subnet mask (255.255.255.0), gateway (router IP) and DNS (usually the same as the gateway).
3. Confirm by pressing OK.

After assigning a static IP, update the printer settings on all devices (PCs, phones). Canon PRINT this is done through Settings → Network Settings → Refresh Printer List.

7. Security: How to protect your printer on a Wi-Fi network

Printers Canon MG3140 vulnerable to network attacks if protection is not implemented. The following measures will help prevent data leaks:

• 🔑 Change the default password to the printer's control panel (if it supports a web interface). By default, many models use canon or admin.
• 🌐 Disable WPS after setup (if you don't use it constantly).
• 📡 Create a guest network for the printer if there are other devices connected to your Wi-Fi.
• 🔄 Update the firmware printer through Canon IJ Network ToolOutdated versions contain vulnerabilities.

To check if someone else has connected to your printer:

1. Go to the router's web interface and look at the list of connected devices (DHCP Clients or Devices on the network).
2. Find your printer by MAC address (printed on the sticker).
3. If there are unknown devices with the same IP, change the Wi-Fi password.

⚠️ Attention: Some viruses (eg. Mirai) scan local networks for openly accessible printers and use them for DDoS attacks. If your printer starts printing strange documents by itself, immediately disconnect it from the network and reset its settings.

FAQ: Frequently Asked Questions about Connecting the Canon MG3140
