If the Canon Pixma MG7720 printer fails to power on at all, or has intermittent power issues, use this guide to replace the power supply. This component is responsible for powering different parts and regulating voltage, and it can also be called the "power supply unit" (PSU). Common problems may occur, such as when the power cord is damaged, when there is a blown fuse, or even if you are using a faulty surge protector (in which it is not providing power at all).
