Question about Canon Office Equipment & Supplies

1 Answer

I need to know if a replacement power supply is available, I bought a PIXMA MX300 about 2 months ago, and we had lightning to run in on our equipment knocking out a lot of our equipment, I think I was better pleased with this piece more than I ever have been with anything I have ever owned, but I cannot get it to come on at all now, Thank you, James Powell

if you suspect lightning or a power surge that caused the problem, if it were lightning could have effected the power supply board, or if it was lightning it could have went in on the cable or antenna connection. to narrow down the problem, check the fuse on the power supply board, if that is ok then with a volt meter check and see if there is 5V volts going to the signal board, that is the board with the antenna connection, one of the plugs that go to the board probably has writing next to the wires in the plug, if no 5V probably the power supply board bad, I almost forgot, when you take the back off look for burnt parts. if you have the 5V going to the signal board now the problem could be signal board or power supply.

Power surges, such as those caused during lightning storms, can often cause power supplies in electronics to fail. Sometimes, if you're lucky, the manufacturer will have placed a protection fuse in the power supply which can be replaced after a surge. If there is no such fuse, the power supply typically will need to be replaced for the equipment to regain function.

It is VERY IMPORTANT to use SURGE PROTECTORS on all electronics, especially if you live in an area where thunderstorms are commonplace. This will protect your electronics from most (not all) surges that would otherwise zap them into failure.

Green power light flashes on and off but no picture or sound.

Sounds like the dreaded power supply is going out, I repaired one 3 months ago with a bad power supply. These units are notorious for power supply failures. Replacement power supplies are available from, or, just to name a few. Personally I would go with, they back their parts up with 6 month warranties. You never know what you are getting on Ebay.

Sounds like the life of your transformer is running out. It is a small and cheap equipment which can be easily damaged by voltage fluctuations or lightnings. All you have to do is replace that item. When having a new one, go for the best thing available in the market. Else the new one too will go out soon.

Screen went black, then small pop noise followed by power going out...power will flash on for a sec. when power button is pushed, but the screen is black and goes off immediatly?

Sounds like your transformer has run out. I had the same problem couple of years ago. It can happen either due to voltage fluctuations or lightning or something similar. All you have to do is replace that cheap and small equipment. Always go for the best one available in the market. Else the new one too can go out soon.

My engine will turn over and catch but wont hold. this has happened 3 times in 2 months, not all the time. acts like it's running out of gas, but there is plenty in it. fuel pump was replaced 2 years ago....

check for power supply at the fuel pump and also interuption in the 12 volt power supply to your ignition coil ...please rate help, thanks...

Intermittened problems are the hardest to diagnose you know, you almost have to be preapred when it happens having all the necessary diagnostic equipment on hand at all times...

I have no power

If you have a fused power supply, make the fuse hasn't blown out. If it has, simple replace it and try again. Alternatively, but a replacement power supply and give that a go.
