Canon PIXMA TS3350 app can't find it: what to do
The Canon PRINT app cannot find the printer during setup.
We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.
Most likely causes
Phone is not on the same Wi‑Fi network as the printer or printer not in setup mode
- Make sure your phone is connected to the same 2.4 GHz Wi‑Fi network you plan to use for the printer.
- Ensure the printer is in Wi‑Fi setup mode (Wi‑Fi light blinking or display shows setup).
- Force‑close the app and reopen it, then choose 'add device' again.
- Signal: the app lists the printer or continues the setup steps.
Phone using mobile data or a VPN blocking discovery
- Turn off mobile data and temporarily disable any VPN or firewall apps on your phone.
- Try searching for the printer again in Canon PRINT.
- Signal: the app detects the printer or can connect.
Printer not actually in the correct connection mode
- Cancel setup and start the printer's wireless setup again (look for 'Wireless LAN setup').
- Wait until the Wi‑Fi light blinks or the app indicates the printer is ready to connect.
- Restart the app and search again.
- Signal: the app detects the printer or proceeds with installation.
Factory reset
Warning: a factory reset erases all network settings and personal preferences. You must set up the printer again in the Canon PRINT app afterwards.
- Turn the printer on and open the 'Setup' or 'Settings' menu on the display.
- Select 'Reset' or 'Restore default settings' (may be under 'Management' or 'System settings').
- Confirm that you want to erase all settings and wait until the printer completes the process.
- After the reset the printer may restart; run the initial setup steps again in the Canon PRINT app.
Frequently asked
Why can't my phone find the printer during setup?
Make sure your phone is on the same 2.4 GHz Wi‑Fi network and the printer is in Wi‑Fi setup mode; disable VPN and mobile data.
Does this printer support 5 GHz Wi‑Fi?
This printer typically works on 2.4 GHz; check that your router offers a 2.4 GHz network and connect to that.
What is lost after a factory reset?
A full reset removes Wi‑Fi settings and personal preferences; you will need to set the printer up again in Canon PRINT.
The app asks for a PIN during setup — where do I find it?
The printer may display a PIN during setup on its screen; enter that PIN exactly into the app if requested.
