If your canon printer wont turn on, it usually indicates an issue with power supply, internal components, or a temporary system glitch. This problem can occur due to a faulty power cable, loose connections, a damaged power outlet, or an internal hardware failure. Sometimes, the printer may appear unresponsive because of a power surge or firmware issue. Checking the power cord, outlet, adapter, and ensuring there’s no internal obstruction can often help resolve the problem. When the device still fails to start, professional servicing may be required to restore normal operation.
