Ed zagorski,
You will need to call the Dell Spare Parts department to see which part you actually need. I dont believe it is just a bulb or lamp. The number to call is 1-877-717-3355. US

Lamp error

How do you know its a lamp error?. if it is the scanner lamp its located under the glass. And you replace the whole module not just the lamp, or is it the fuser lamp, you just replace the whole fuser section which is the Hot part.

Lamp expired can I find a new lamp & can I replace it myself

Hello Ann Welford,

Welcome, and thank you for using FixYa!

To answer your question: I don't recommend replacing the bulb on this unit.
Not only did HP design these scanners in such a way as to elimnate "User changable parts" but it would not be cost effective. You can buy a replacement scanner for this unit for close to $75.00 and it will have newer features and software controls.

Have a great day!

Lamp burned out!

You can certainly get a replacement lamp but due to the complexity of replacing it I recommend you get a new scanner. In most cases the lamp will cost you more than the scanner did originally.

I have a printer I need to know how to open it to get to the ink its a A940 dell

The lid (the top few inches) is supposed to lift up. It might be a little stuck. It's hinged at the back like the scanner cover.

You can download a manual at

Check pages 39 and 40 for replacing ink cartridges.

Go into Control Panel and complete the Scanner Wizard provided by Windows XP, then try scanning pictures or documents again. If you have the disk to the printer/scanner autorun the installation again. It will just overwrite the old install, not a big deal. If you do not have the disk, look online for the "free installation disk Dell A940 Printer/Scanner" and run from this free website. Let me know how it goes.

Lamp failure

The E6 Scanner lamp can be substituted by a standard
F8T5CW lamp. It is 12 insches long, uses 8 watts, is in the
T5 tube size with two prongs at each end and cool white, not
warm white. The replacement lamp works fine.
