Question about Canon PIXMA MP830 All-In-One InkJet Printer
No fuse or breaker on this model, Most times this problem is caused by a bad printhead. When they go bad it doesn't allow the printer to power up. If the printhead is not locked in the corner, you remove the inks and printhead and try powering again. It will give the no printhead error if that's the problem. If you put that printhead back in you can ruin the main logic board. You just buy a new printhead.

Yes there is a glass pigtail fuse on the printed circuit board of the power supply. The problem is getting into the power supply housing. It's not meant to be accessed but can be done. I removed mine from the board and it tested bad. The other problem is finding the same type and rated fuse. Good luck with that. It wasn't meant to be. Good news is that you can buy a new power supply from Canon for about thirty bucks and it's a breaze to replace. It's located where the power cord plugs into the unit and has only one screw securing it. Five minutes or less to replace.

Check that the power cord is securely plugged into the power outlet.
Make sure that the power outlet is receiving electricity by plugging a different device into the plug and turning the power on. If the other device does not work you likely have a blown fuse or tripped circuit breaker.
Replace the blown fuse or reset the circuit breaker as needed. If it happens again, an electrician should assess the problem.
