Re: scanner still scanning black, I don't think it was...

Well, I was HOPING that your problem was simply caused by a burned-out bulb, but since you can see a BRIGHT light when you use the scanner, the bulb is WORKING, and it is NOT the cause of your problem... Unfortunately, the only other known cause of "black scans" for your Microtek S400 scanner requires you to follow a rather complicated procedure to correct the problem, so I am in the process of typing detailed instructions for you to follow. I will post them here as an addditional comment as soon as I finish typing them, and hopefully, they will help to guide you through this process. I am posting this now simply so you will know that I am still working on helping you to resolve this; according to the Microtek Knowledge Base, there are several steps you MUST follow exactly in order to eliminate the cause of the black scans, so I ask for your continued patience while I finish my research into your problem. The instructions Microtek provides seem somewhat complicated, so hopefully, the instructions I'll post here will help you to understand the steps Microtek requires you to follow to correct this problem. Again, the solution to your problem requires that you follow several specific steps (Step 1 through Step 10), in order, depending on which version of the Scan Wizard software is installed on your system, so I will post more information here that should help to guide you through the entire process. If the first solution Microtek suggests does NOT correct your problem (following Steps 1 through 10), you will have to follow Step 11 in order to complete the process of removing the Scan Wizard software. Obviously, such a multi-step process will require a good deal of patience, and attention to details, which is why I'm trying to simplify the entire process for you... I'll post the steps here as soon as I finish typing them; please read through them, and if you have any questions for me, post them here, and I will try to answer them for you BEFORE you begin following the multi-step repair process... After seeing all of the steps involved in correcting this problem, I'm thinking of changing my screen name to ScannerHater...

They are getting a warning on the light bulb\r\nSense Key=0x4 ASC=0x680 DDES=0x7E

Hi Dana,

The error you are receiving is Flatbed Optical Alarm.This alarm occurs when the READ command for the first document is received, or when gain of the CCD amplifier is adjusted (sheet guide is read) during scanning.Probable causes are:
- The lamp, optical system or white sheet guide is dirty
- Defective lamp, heater, CCD, or inverter
- Connector disconnected
  1. Does the same symptom occur after turning OFF and ON the scanner? Check the scanner.
  2. Is the White sheet guide (glass) in the FB cover dirty? Remove the FB cover and clean the White sheet guide (glass).
  3. Is the Optical unit dirty?Are cables damaged?Are the connectors connected properly?Check all.
  4. Do the Lamps FB light up?Are cables damaged? Are the connectors connected properly? Check if the lamps light up during the Paper feeding test.If not, the error is caused by the defective Lamp FB or Inverter.
Hope the above information is helpful.

Thanks & regards,

Where can I buy spare parts? i need a new lamp.

I have a Agfa DuoScan F40 Flatbed Scanner. It appears that the scanning function is not working. Light is not turn on.Blank white paper as a result.
I wonder if we could somehow mod the scanner lamp since it is nearly impossible for us to buy the scanner lamp nowdays,even Agfa support say so.
The function of this lamp is similiar to a torchlight.It will brighten the document that we want to scan during the scanning proces.What if somehow we manage to use other device other than the lamp it self like superbright LED(20 watts) or another lamp scanner from dead scanner macine.I think it will work.Anyone care to comment....

Scanner gives poor quality scan...bulb?

I have one with the same problem. Look at the lamp. If it isn't really bright, that could be the cause. Mine is bright at one end and that is the side of the page that is good. I am not an expert so I could be wrong, but that is where to start if all else looks OK. Am looking for a cheap replacement lamp myself. But at the prices of all-in-ones, it's not worth spending much.

No letters come out or pictures

It quite simple to verify if the lamp is out. Just leave the the cover open and then switch the scanner on. The lamp should light up as the scanner initializes. Note if the full length of the lamp lights up. If it lights up only partially, then the lamp needs to be replaced. I doubt if the lamp is the problem though.

It is quite simple to get to the lamp but, you do need to be a little tech-savvy and own a soldering iron. Disconnedt the mains from the scanner. Turn over the scanner; the top is secured to the bottom by two recessed clips at the front button; release them with a screw-driver. Unsolder the two ends of the lamp. A new lamp can be purchased at a shop that sells computer spare parts. It's similar to the lamps that are used as back-lights in LCD screens. They come in different lengths so make sure you get one of similar length and solder it back in place.

Lamp replacement

Just replace the lamp! It's just a fluorescent light you can get anywhere. You don't need a new scanner, if I had to replace the scanner every time the lamp died I be in the poor house!
