I inherited one of these from a friend, but it has no power supply, no CD-ROM, just the scanner. I rigged up a 12V power supply for it, and a couple lights come on, but it's not clear the thing is still alive. Before installing the 60mb of software I found at HP, I'd like to make sure the scanner isn't obviously DOA.
Without connecting it to the computer, when I just power up the scanner, I get two LEDs - the Power Save LED on the left, and the Color indicator on the right. There's nothing in the little LCD window. Pushing the Power Save toggle button has no effect - the LED stays on.. The same is true with the Color/B&W toggle button. No other buttons have any effect.
Is this normal for a powered-up but unconnected 4470C? Is there any kind of stand-alone powerup self test I can make it do?
Thanks for any help.
