First try a hard reset. Use the following steps to perform a hard reset on an HP Scanjet Scanner.
1. Disconnect all cables from the scanner.
2. Lock and unlock any carriage lock.
3. Place the scanner on a flat and level surface.
4. Wait at least 5 seconds after disconnecting the cables before re-connecting any cables for testing or troubleshooting.

If the bulb is indeed fused, you will need to get the device serviced. This cannot be done by yourself, as the lamps are not sold separately..You can contact HP here:

Hope that helps! Should you have any further questions,please feel free to post them here.

try this:
1. check your usb port (if possible try another)
2. make sure the scanner has enough power (if not use stabilizer)
3. Try using windows scan instead of software scan. i.e scanner and camera wizard
4. if you are using windows vista or 7 try running the application as an administrator

this should work
of not contact a nearby technician

I get an error saying: scanner could not be initialized scanner not found. and i have it all hooked up right. and its worked for years now all of a sudden it isnt working.

Have you plugged it into a different USB port recently. If so either delete the printer from Device Manager and let the system find it again. Or plug it back into the original USB port.

Driver for windows vista home premium sp1

HP doesn't have a Vista driver for Scanjet 3400c. I'm afraid your scanjet isn't compatible with Vista.

I have a new pc with windows vista and I can't install my scanjet 3400c because hp has not got the drivers for vista. I've tried some solutions from the net but it seems they haven't worked. Is there any...

You can still use the scanner to scan, but the buttons on the front won't work any more and you have to perform those operation (print, email) manually. Pressing the buttons opens a dialog box allowing you to scan your item.
