The most common cause is a driver mismatch—like installing the wrong maker’s driver—or having the wrong default printer set, though connection problems and printer status conflicts can also cause this.
1. Perform a Cold Restart of the Printer, Router, and System
A temporary communication glitch between the printer and your system may cause the error state. Performing a cold restart of the printer, router, and system can often clear the glitch and solve the problem. Before you do that, check if any lights are blinking on the printer. If so, check Canon’s website to understand the light pattern and troubleshoot accordingly. For example, if the B and C lights are solid (not blinking), you may need to replace the ink cartridges.
2. Disable the Firewall/Antivirus of the System
You may see the error state if your firewall/antivirus blocks a module required for the printer driver or app to run. In this case, temporarily disabling the firewall/antivirus can help confirm the cause. When finished testing, turn your antivirus and firewall back on.
3. Reset the Router to the Factory Defaults
Your PC might fail to find the printer if the router’s firmware is corrupted, which can lead to this error. Also, if you recently replaced the router, the printer may not be communicating properly. Resetting the router to factory defaults can help.
4. Reinstall the Canon Printer Software/Driver
If the Canon printer driver/software is corrupted, you may see the error state. Reinstalling the printer app/driver often fixes it. Before you begin, make sure there isn’t a print schedule on the system or printer that limits printing (for example, office hours only).
5. Re-Add the Wi‑Fi Network to the Printer
The error can also appear due to a problem with the network type in use. For example, if you’re on Wi‑Fi and the printer’s Wi‑Fi card (or your network) has an issue, the error may show up. Switching to another connection type can help. If you are using Wi‑Fi, check if using a LAN (Ethernet) connection to the printer solves the problem. If that’s not an option, try adding the Wi‑Fi network to the printer again as shown below (steps may vary by model, but the idea is the same). Before you begin, make sure the printer can print a test page. If the issue persists, you may need to contact Canon regional support for further help.
