I Just used the wrong power supply on my 3400c and it quit working, turns out the power supply was a 24volt, were it came from or what it was doing in my house i have no idea, it looked like the same one so i used it. BIG MISTAKE. Im pretty sure all i need is the main board that everything plugs into but hp doesnt have it and i've looked all over ebay with no luck there either. I dont want to spend money on a new scanner either. If someone knows where i can find one of these it would be greatly appriciated. THANX I should be able to post a picture of it soon.

To be honest, its probably going to be cheaper to buy a new scanner as we had another person on here searching for an official HP power pack and just couldn't find anything EVEN going through HP. They just aren't interested in selling things seperately.

A very quick look found it for £64 / $100 http://www.anyweb.co.uk/computers/listings/243.html

I'd be happy if I was wrong though.
