Showing error code B203 then you need to check for the installed. Every Canon printer model has a different driver. If you are using a new printer then make sure you have installed its driver. Sometimes, the user adds a new printer but forgets to install the driver. You should go to the drivers’ folder and check for the Canon driver. Open the drivers’ list and you will search for the printer driver. Check the name of your printer driver. If you have the wrong driver then uninstall it from the device. Right-click on it and tap on the Uninstall button. Restart the device and visit the Canon website. Now search for the correct printer driver. Check the Canon printer model and download the driver. Install the driver on your device and then reconnect the printer. Your printer will take a few seconds to recognize the driver. The Canon printer will show Ready to Use status and now you can easily take your printouts.
Reconnect your Canon printer to the router
People often get B203 error codes in Canon printers while connecting to Wi-Fi. The error can appear when the WPS pin is not working correctly. You should try restarting the router. Go to the router and restart it. Now check the Canon printer and restart the Wi-Fi button. Printer’s Wi-Fi lamp will start blinking. The lamp will blink and the printer will search for available networks. Go to the printer screen and you will see a list of available networks. Click on the correct network and hit the Confirm button. A password wizard will appear, enter the password. After connecting the printer to the router, go to the PC connected to the same network. Send a print job and take printouts with your Canon device.
