If your Canon printer isn’t turning on1-877-331-5006, first check the power cord and make sure it’s plugged into a working outlet. Try a different power socket or use another power cable if available. If using a surge protector, connect the printer directly to the wall. Press and hold the Power button for a few seconds. If the printer still won’t start, unplug it for 5-10 minutes, then reconnect it. In rare cases, a blown fuse or internal hardware issue may be the cause, requiring service from Canon support or a certified technician.
