You'll need a few critical, equally important, items.
- CCFL Bulb - preferably in it's holder assembly
- CCFL inverter - will have some wire going in, and some high voltage wire going out (to the bulb)
- Power Supply
Where to find?
The bulb will be on the scanner carrier along with the scanner CCD. It's likely to be in a plastic housing. The inverter will be close by too.
The power supply will be a little more tricky. You'll need to determine how much power your inverter requires. It may be printed on the inverter - or not. In this case, it was not. First, I tried 12 volts - any 12V source will work. This resulted in a half lit bulb - the center of which being dark. Then, I tried the 30V power supplied that came with the printer. Voila, it worked.
