If your canon printer wont turn on, it could be due to power supply issues, faulty cables, or internal hardware problems. Start by checking that the power cord is securely connected and the outlet is working. Try unplugging the printer for a few minutes and plugging it back in. If the printer still doesn’t respond, there may be an internal fault requiring professional repair or Canon support. This issue often arises from power surges, damaged cords, or faulty adapters.
