Connecting a Canon MG3540 printer to your phone via Wi-Fi: Complete instructions with photos and tips

Wireless printing from your smartphone saves time and eliminates the need to transfer files to your computer. Canon PIXMA MG3540 — a popular Wi-Fi-enabled model, but setting it up via a mobile device often raises questions. Unlike modern printers with NFC or cloud services, this model requires manual network configuration. The main difficulty lies in synchronizing the router and printer settings, especially if the network uses dual-band mode (2.4/5 GHz) or non-standard security settings.

Many users encounter errors like "Unable to connect to printer" or "Device not found" - this is due to the peculiarities of the protocol WPS or an incorrectly selected Wi-Fi mode. In this article, we'll look into three official methods connections (via WPS, manual setup, and the Canon PRINT app), and we will also solve typical problems: from the printer being invisible on the network to printing failures with Android 13+ or iOS 17If your router doesn't support WPS or your printer was previously connected to a different network, don't worry, we've provided alternative options.

For successful setup you will need:

• 📱 Smartphone on Android 6.0+ or iOS 12+ with the current version of the application Canon PRINT
• 🖨️ Printer Canon PIXMA MG3540 with Wi-Fi turned on (the indicator should be flashing orange or green)
• 📶 Router with enabled Wi-Fi 2.4 GHz (The printer does not work on the 5 GHz network!)
• 🔑 Your Wi-Fi network password (if you use manual setup)

1. Preparing the printer and phone for connection

Before setting up Wi-Fi, make sure the printer is Canon MG3540 ready for use. Plug it into the power supply and wait for the self-test to complete (the indicator Power will stop blinking). If the printer was previously connected to a different network, reset the network settings: hold down the button Wi-Fi for 5 seconds until the indicator starts flashing quickly.

On your phone, check:

• 📶 Wi-Fi is on and the phone is connected to the same network as the printer (if you set it up manually)
• 🔄 Airplane mode is disabled - it blocks all wireless connections
• 📱 Bluetooth is off (may interfere with device search on some Android versions)
• 🔒 Canon PRINT app permissions: network, storage, and location access

Critical detail: printer MG3540 works only online 2.4 GHzIf your router broadcasts two networks (for example, MyWiFi_2G And MyWiFi_5G), connect your phone and printer to a network with the suffix 2G or without it (usually 2.4 GHz). You can temporarily disable 5 GHz in your router settings to avoid confusion.

⚠️ Attention: If your router uses hidden SSID (the network name is not broadcast), the printer will not be able to connect to it. Temporarily make the network visible or use the WPS method.

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

Protocol WPS (Wi-Fi Protected Setup) Allows you to connect your printer to the network without entering a password. This method works if your router supports WPS (usually there's a button labeled "WPS" or with a 🔄 icon). Instructions:

1. On the printer, press and hold the button Wi-Fi (📶) until the indicator starts blinking quickly (WPS mode).
2. For 2 minutes press the button WPS on the router. The printer's indicator light should turn green.
3. Open the app on your phone Canon PRINT and wait until the printer appears in the list of available devices.

If the printer is not displayed:

• 🔄 Restart your router and printer, and repeat the procedure.
• 📵 Make sure there are no physical obstacles (walls, metal objects) between the router and the printer.
• ⚙️ Check your router settings to see if WPS is enabled (sometimes it is disabled by default).

⚠️ Attention: Some providers (eg Rostelecom or Beeline) disable WPS in the router's default firmware. If there is no WPS button, use manual configuration (method 2).

3. Method 2: Manual connection via the printer menu

If WPS is unavailable or doesn't work, set up a connection manually from the printer control panel. This method is universal, but requires knowing the Wi-Fi password.

1. On the printer, press and hold the button Wi-Fi (📶) until the indicator flashes once (manual setting mode).
2. Click the button Black and white copy (⚪), then the button Wi-Fi (📶) onceThe indicator will start flashing quickly.
3. On your phone, open the list of Wi-Fi networks. Find the network with the name CANON_XX_MG3540 (where XX are unique characters) and connect to it. No password required.
4. Once connected, open your browser and enter the address http://192.168.1.1 (or http://canonijsetup). The web configuration interface will open.
5. Select your home network from the list, enter the password, and save the settings. The printer will reboot.

If the web interface doesn't open, check that your phone isn't using a VPN or proxy. Also, try entering the IP address. 192.168.0.1 or 192.168.11.1 - They sometimes differ depending on the region.

4. Method 3: Connecting via the Canon PRINT app

Official app Canon PRINT (available for Android And iOS) simplifies setup, but requires the printer to be connected to the network first. If you've already set up Wi-Fi using one of the previous methods, follow these steps:
