To reset your Canon printer during the ij start canon setup, first turn on the printer and ensure it is connected to a power source. Press and hold the “Stop” or “Reset” button until the alarm lamp flashes, usually about 15 seconds. Release the button, and the printer will restore its factory settings. This clears previous network configurations, allowing you to restart the setup process via ij.start.canon . After resetting, reconnect the printer to your Wi-Fi or computer, and reinstall the drivers from the official ij start canon website. This ensures a smooth installation and resolves most connectivity or setup issues.
