Canon Printer Error Code 3200 — What It Means & How to Fix It

What Does This Error Mean?

Canon error 3200 indicates a communication problem between the printer and a connected device or network. The printer tried to send or receive data and the connection failed or timed out. This most commonly affects wireless-connected printers but can also occur on USB connections.

Affected Models

Canon PIXMA TR4520
Canon PIXMA TS3320
Canon PIXMA MG3620
Canon MAXIFY MB2720
Canon PIXMA G4210

Common Causes

The Wi-Fi connection between the printer and router dropped or was interrupted during a print job
The router changed its IP address and the printer is still trying to connect to the old address
A USB cable is damaged, loose, or not fully inserted into both the printer and computer
The computer's firewall or security software is blocking communication with the printer
The printer's wireless settings are misconfigured — for example, the saved Wi-Fi password is outdated after a router change

How to Fix It

Restart your printer, router, and the computer you are printing from. Do this in order: router first, wait 30 seconds, then printer, then computer.

Restarting the router forces it to reassign IP addresses cleanly, which often resolves the communication mismatch that causes error 3200.
On the printer, go to Settings > LAN Settings > Wireless LAN Settings and confirm it is connected to the correct Wi-Fi network.

If the printer shows 'Not Connected' or is connected to the wrong network, run the Wireless Setup Wizard to reconnect it.
On your computer, open Devices and Printers (Windows) or System Preferences > Printers & Scanners (Mac). Remove the printer and add it again.

When you re-add the printer, your computer will rediscover its current IP address rather than trying to use an old, stale one.
If using USB, try a different cable and a different USB port on your computer. Test the cable with another device if possible.

USB cables can fail gradually — intermittent errors with no visible damage to the cable are a common sign of a failing cable.
Temporarily disable your computer's firewall and antivirus and try printing. If it works, add the Canon printer software to your firewall's allowed programs list.

Remember to re-enable your firewall immediately after testing. This step only confirms whether software is blocking communication.

When to Call a Professional

If error 3200 occurs consistently even after fixing the network connection and reinstalling drivers, the printer's wireless module may be failing. Canon service centers can test the wireless hardware. For budget Canon PIXMA models, replacement is often more economical than a wireless module repair.

Frequently Asked Questions

Why does error 3200 appear only sometimes and not every time?

Intermittent error 3200 usually points to an unstable Wi-Fi connection. The printer and router are far apart, the signal is weak, or there is interference from other devices. Moving the printer closer to the router or switching it to a 2.4 GHz network (which has better range than 5 GHz) often resolves intermittent failures.

My printer was working fine — why did error 3200 suddenly appear?

The most common trigger is a router change or a change in your Wi-Fi password. If you got a new router, changed your Wi-Fi password, or your internet provider replaced your modem/router, the printer's saved credentials are now outdated. Run the Wireless Setup on the printer again to reconnect it with the new credentials.

Can I use the printer via USB to avoid error 3200 while I fix the network issue?

Yes, absolutely. Connecting via USB bypasses the wireless connection entirely and lets you keep printing while you sort out the network problem. You may need to install the USB driver — use the original Canon disc or download the driver from Canon's website.
