Re: no power

Same problem, too. It must be that planned obsolescence. HP wants $125 for a replacement - right! I got one at a surplus electronic store for $12.95. Make sure it is 12V and at least 1250 mA.

Pinout Details for HP C7671B transparency adaptor mini din connector

Cut the mini din wire, you will see four wires inside the sleeves. The red wire is positive terminal, and black wire is negative terminal. Use any 12V DC adapter to connect. The adapter will light up. Good Luck.

Power adaptor?

If you need a replacement, you have two choices. Visioneer no longer makes this scanner, but they do offer replacement power adaptors. They run about $20 plus shipping. It may be quicker (and cheaper) to look on the scanner (maybe on the bottom or on the back, probably beside the power jack) or on the current adaptor itself and see what the power rating is. It will say something like "6 VDC, 1A" or "5.5 VDC, 3-5A". These are the two power ratings you need. VDC is the DC voltage, and A is the amperage. You can take the power adaptor to a local Radio Shack or similar electronics shop, and they'll help you with an appropriate adaptor. You may also be able to find an appropriate adaptor at a large electronics store (like Best Buy) or a large discount store like Wal-Mart or Target. Just go to the electronics section. A small speciality shop will probably take the adaptor and give you the choice of one or two that will work. In a larger store, you may not get as much help, so you just want to match both power numbers on the package, then make sure the plugs on the end of the power cords match, so the new one will fit your scanner (universal adaptors often include several tips that can be put on the end of the power cord; just make sure one of them is the same size and shape as yours).

Can 15 volt power adaptor be used on an 18volt scanner?

you dont have other choice, how about to buy an multi plug-in adaptor from 3V up to 23V can manage the voltage of your scanner, but if not this 15volts can support your scanner..

CanoScan8400 Suddenly Doesn't Work

I had the same problem about a year ago. The solution was to replace the power cord AND don't leave it connected to the powers source when the scanner is not in use, or it will burn out again.

Acer flatbed scanner

If you didn't put the correct adaptor in the scanner that can happen. I did it once before.

See if there are any specs for the power supply on the bottom of the scanner or on the area where you plug it in at.

I wouldn't run it until it is verified because you can damage the scanner by not having the correct power supply plugged into it.

You can check with and the website should tell you or someone from their tech support should have the information.

Good luck on that.
