Canon Printer Error Code 3000 — What It Means & How to Fix It

What Does This Error Mean?

Error 3000 on a Canon printer means the printer failed to connect to the network or wireless router. The printer cannot find or communicate with your Wi-Fi network. This is usually fixed by re-running the wireless setup or restarting your router.

Affected Models

Canon PIXMA MG5700 Series
Canon PIXMA MG6800 Series
Canon PIXMA TS5100 Series
Canon PIXMA TS6100 Series
Canon PIXMA MX920 Series

Common Causes

The Wi-Fi password entered during setup was incorrect
The printer is too far from the router and the Wi-Fi signal is too weak to maintain a connection
The router was restarted or replaced and the printer's saved network settings are now outdated
The network name (SSID) changed and the printer is still trying to connect to the old name
The printer's network settings became corrupted after a firmware update

How to Fix It

Restart your Wi-Fi router by unplugging it from power, waiting 30 seconds, and plugging it back in.

Routers can develop connection issues over time that affect new and existing devices alike. A restart often fixes them instantly.
On the printer's control panel, navigate to Settings > Wireless LAN Setup or LAN Settings and select 'Reset Network Settings'.

This clears any outdated or corrupted Wi-Fi settings stored on the printer so you can start fresh.
Re-run the wireless setup wizard on the printer. Select your network name from the list and enter the Wi-Fi password carefully.

Wi-Fi passwords are case-sensitive. Double-check every character — this is the most common cause of setup failure.
Move the printer closer to the router temporarily to rule out a weak signal as the cause.

If the printer connects successfully when close to the router, a Wi-Fi extender or relocating the printer may be needed.
Check that your router is broadcasting at 2.4 GHz — most Canon PIXMA printers do not support 5 GHz Wi-Fi networks.

Many modern routers broadcast both 2.4 GHz and 5 GHz. Make sure you are connecting to the 2.4 GHz network.

When to Call a Professional

Error 3000 is almost always a Wi-Fi configuration issue that does not require a technician. If the printer's wireless card is physically damaged, it may need repair — but this is rare. Contact Canon support if the printer fails to connect after multiple fresh setup attempts.

Frequently Asked Questions

Does my Canon printer support 5 GHz Wi-Fi?

Most Canon PIXMA consumer models only support 2.4 GHz Wi-Fi networks. If your router broadcasts a combined network with one name for both bands, try connecting to just the 2.4 GHz band. Your router's admin panel lets you split the two bands into separate network names.

Why does my printer keep losing the Wi-Fi connection?

Intermittent disconnections are usually caused by weak signal, router firmware issues, or IP address conflicts. Assign the printer a fixed IP address in your router's settings to prevent conflicts. Moving the printer closer to the router often improves stability dramatically.

Can I use the printer with a USB cable while I fix the Wi-Fi issue?

Yes. Connect the printer directly to your computer with a standard USB cable as a temporary workaround. This bypasses the wireless connection entirely. You may need to install a USB driver if you previously only set up the printer for wireless use.
