Using a Non standard adaptor with an HP Scanner - will this work / safe?

sillywilly

Hi all,

Just dug an old HP scanner out the garage but when I got out the box I realised I had put my old knackered Epson scanners AC adaptor in with it.

The HP scanner I want to use says 15V = 0.800A

But after going through my cables box I have a wide range of adaptors, 24V 20V, 19V loads of 12V, 9V adjustable - but not the original anywhere. Think I must of lobbed it with the broken scanner!

Anyway after going through all the adaptors in the house I eventually found one on a Vestax mixer. It says OUTPUT 15V = 0.5A 7.5VA

Can anyone let me know if this one will work without damaging either item? If not does anyone know if any of the other mentioned adaptors would work?

Many thanks in anticipation of your help

Cheers

You need...
The same connector or the ability to change it
The same or close to the same voltage (10% over should be ok 10% under may work or not but shouldn't break anything)
The same polarity (usually the inner is +ve but certainly not always)
A current rating of at least what the original adaptor could deliver

It's on the last point that your 0.5A adaptor fails. It may either simply not work or overheat. If stuck I'd try it with caution but I wouldn't offer that as advice to others if you can understand what I mean by that.

Oh yes - one final point - most things need DC but not all - it has to be AC for an AC unit and DC for DC to be certain there will not be a problem.
