How do I perform a factory reset on a Canon G3020 to resolve a persistent 'Printer Error'?

A factory reset will erase all settings. Consult the Canon G3020 user manual for the specific steps, as they can vary slightly depending on the firmware version. Typically, it involves navigating through the printer's menu to find the reset option. Be aware that you'll need to reconfigure your Wi-Fi settings and other preferences after the reset.
