How to Connect Canon TS3120 Printer to WiFi?

Oct 23, 2026 3 min read 82 views

The Canon PIXMA TS3120 is a compact wireless printer that can print from any device on your home network once it is connected to WiFi. Setting it up wirelessly is straightforward but the printer does not have a touchscreen which makes the process a little different from other Canon models. Here is how to get it connected.

Before You Start

Make sure you have your WiFi network name and password ready. The Canon TS3120 only supports 2.4GHz WiFi networks so if your router broadcasts both 2.4GHz and 5GHz bands, you will need to connect to the 2.4GHz network. Also make sure the printer is powered on and has ink cartridges installed. Place the printer within a reasonable distance from your router for a strong signal during setup.

Method 1: Connect Using the Canon PRINT App

The easiest way to set up the TS3120 wirelessly is through the Canon PRINT Inkjet app on your phone. Download the app from the App Store or Google Play. Open the app and tap the plus icon to add a new printer. The app will guide you through putting the printer into wireless setup mode by pressing and holding the WiFi button on the printer until the lamp blinks. Then the app will detect the printer, ask you to select your WiFi network, and enter the password. Once connected the WiFi light on the printer will stay solid.

Method 2: Connect Using WPS Push Button

If your router has a WPS button this is the fastest method. On the Canon TS3120 press and hold the WiFi button on the top of the printer until the WiFi lamp starts flashing. Then within two minutes press the WPS button on your router. The printer and router will negotiate the connection automatically. When the WiFi lamp on the printer stops flashing and stays solid the connection is complete. No password entry is needed with this method.

Method 3: Connect Using Windows PC

Download the Canon TS3120 driver and setup software from the Canon support website. Run the installer and select Wireless LAN Connection when prompted. The setup wizard will walk you through putting the printer into setup mode and connecting it to your WiFi network. Follow the on-screen instructions to enter your WiFi password. Once the connection is established the installer will finish setting up the printer driver on your computer.

Troubleshooting: Canon TS3120 Not Connecting to WiFi

If the printer fails to connect, first make sure you are using the 2.4GHz band and not 5GHz. Power cycle the printer by turning it off, unplugging it for 30 seconds, and plugging it back in. Reset the printer network settings by pressing and holding the Resume button until the alarm lamp flashes 11 times, then release it. This clears all saved WiFi settings and lets you start the setup from scratch. Also check that your router is not blocking new devices or has MAC filtering enabled.

Verify the Connection

After the setup is complete, print a network configuration page to confirm the printer is connected. Press and hold the Resume button on the printer until it prints a page showing the network details. Check that it shows Connected next to the WiFi status and that the IP address and router name match your network. Try printing a test page from your computer or phone to verify everything works end to end.

Canon TS3120 WiFi Setup FAQ

Q1. Can I connect the Canon TS3120 to WiFi without a computer? Ans: Yes, you can set up the Canon TS3120 wirelessly using just your phone and the Canon PRINT Inkjet app. Download the app, follow the setup wizard to put the printer in wireless mode, select your WiFi network, and enter the password. You do not need a computer at any point during the setup process. The WPS push button method also works without a computer.

Q2. Why does my Canon TS3120 keep disconnecting from WiFi? Ans: Frequent disconnections usually happen because the printer is too far from the router or there is interference from other devices. Move the printer closer to the router and make sure there are no thick walls or large metal objects between them. Also check if your router firmware is up to date as older firmware can cause compatibility issues with wireless printers. Setting a static IP for the printer in your router DHCP settings prevents it from losing its address.

Q3. Can I print from my iPhone to the Canon TS3120 over WiFi? Ans: Yes, the Canon TS3120 supports AirPrint which lets you print directly from any iPhone or iPad without installing extra apps. Make sure the printer and your iPhone are on the same WiFi network, open the document or photo you want to print, tap the Share button, select Print, and choose the Canon TS3120 from the printer list. The printer will appear automatically as long as both devices are on the same network.
