Scanner Tube?

It is a Very bright light.

To allow for High resolution colour images.

Thanks Sapper for replying so quickly. Do you have any idea of the voltage and maybe frequency this operates at? Does it need a "starter" like fluorescent tubes?

Not sure about power or type of light, might be worth putting meter on the supply...If it's still in one piece ???

What is your avatar a picture of? Can't really make it out other than it's equipment of some sort - which gets me to thinking that CR4 ought to have an enlarge picture function. Hmmm....

Mike, its the CCFL (Cold Cathode Flourescent Light) that is used to illuminate the object being scanned.

Its very fragile and operates with out heaters just a high starting voltage to kick it into life around 600 volts I think.

I'm looking at several at the moment through my LCD monitor.

John.

I agree.

I haven't checked the ones in scanners. The ones I have checked (laptop screen backlights) ran on around 300V from an inverter. I've never paid attention to whether they have a diode or bridge on the output, so it may be AC or DC... If it is AC its high frequency.

The one shown is pretty long, so you may well be right on the higher voltage.

Seems to me, it is the light source for the scanner

I'm not trying to take apart a scanner ,but for 2 days trying to reinstall a scanmaker x6EL. It stopped working when I changed from Microsoft home to Microsoft xp. Fallowed every page of instruction I found on the computer and the original and CD that came with it. I bought it with the computer , had to copy long paper old European documents, now I need it again .

Any help out there , if not I will take a screwdriver to it too.
