Question about Canon PIXMA MP830 All-In-One InkJet Printer
Printer shows no sign of power. Have tested the outlet and it is fine and functional. Is there a fuse that could have failed?
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.

Unplug from the wall for at least 20 minutes to let the capacitors drain.

Dead appliance, power on wall outlet.
SAFETY IS PARAMOUNT!
this only if you are competent.
your appliance has absolutely no functions at all, remove it from the
mains supply, remove the case and see where the mains lead goes in to
the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.
