Canon Printer Error Code 3402 — What It Means & How to Fix It

What Does This Error Mean?

Canon error 3402 means the printer could not connect to Canon's online services. This error appears when using features like Canon PRINT app, Google Cloud Print, or Canon cloud services. It is a network or server connectivity issue, not a printing hardware problem.

Affected Models

Canon PIXMA TR series
Canon PIXMA TS series
Canon PIXMA MG series
Canon MAXIFY MB series
Canon PIXMA G series

Common Causes

The printer is not connected to your Wi-Fi network or the connection has dropped
Canon's cloud servers are temporarily unavailable for maintenance
Your home network's firewall or router is blocking the printer's connection to Canon's servers
The Canon PRINT app on your phone or tablet has outdated settings
Your router's connection to the internet has been interrupted

How to Fix It

Confirm the printer is connected to your Wi-Fi. Check the Wi-Fi indicator light on the printer — it should be solid, not flashing. A flashing light means it is not connected.

If the Wi-Fi light is off or flashing, re-run the wireless setup from Settings > LAN Settings on the printer.
Restart your router and printer. Unplug the router for 30 seconds and plug it back in. Turn the printer off and on after the router reconnects.

A router restart often resolves cloud connectivity issues caused by stale routing tables.
Check Canon's service status. Visit usa.canon.com/support on your phone to see if there are any announced outages or maintenance periods.

Canon cloud services have scheduled maintenance windows. If Canon's servers are down, wait and try again later.
Update the Canon PRINT app or Canon Print Service plugin on your phone or tablet to the latest version from the App Store or Google Play.

An outdated app may use old server addresses that are no longer valid, causing connection failures.
If using cloud printing is not essential, try printing directly via your local Wi-Fi network instead. The Canon PRINT app supports both local and cloud printing.

Local Wi-Fi printing (printer and phone on the same network) is faster and more reliable than cloud printing.

When to Call a Professional

Error 3402 is a connectivity issue and does not require printer repair. If cloud features remain unavailable after trying all steps below, contact Canon Support at usa.canon.com/support. Note that traditional USB and local Wi-Fi printing work independently of Canon's cloud services.

Frequently Asked Questions

What is Canon cloud printing and do I need it?

Canon cloud printing lets you print from anywhere using the internet, even when you are not on the same network as your printer. It routes your print job through Canon's servers to your printer at home. For most home users, local Wi-Fi printing (being on the same network) is simpler and more reliable.

Does error 3402 affect normal home printing?

No. Error 3402 only affects cloud-based features. Printing from your computer at home over your local Wi-Fi or via USB works completely independently. Cloud features are optional — you do not need them for everyday printing.

How do I print from my phone to a Canon printer without using the cloud?

Make sure your phone and printer are both connected to the same Wi-Fi network. Open the Canon PRINT app, select your printer, and print — this uses local Wi-Fi, not the cloud. If you do not have the app, you can also use Apple AirPrint (iPhone) or Mopria (Android) to print directly.
