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...

    According to the Microtek Knowledge Base, BLACK SCANS are caused by corrupted files in the Scan Wizard data folder. You can read the explanation here:

    As you can see, the FIRST step in correcting this problem is to follow the STEP-BY-STEP instructions they provide, as shown on this page:

    The SPECIFIC steps you must follow will depend on knowing which version of the Scan Wizard program is installed on your computer. The instructions are NOT the same for all versions of Scan Wizard; they vary for the following versions of Scan Wizard:

    >> >> If you have ScanWizard 2.48 through ScanWizard 2.60

    >> >> If you have ScanWizard 5.01 through ScanWizard 5.991

    >> >> If you have ScanWizard 5.77 through ScanWizard 5.95

    >> >> If you have ScanWizard Pro

    Open the Control Panel, then open Add or Remove Programs. Next, click on the Change or Remove Programs button in the upper-left corner of the window; within a few seconds, you will see a list of most of the programs installed on your computer. Scroll down through the list until you find the entry for Scan Wizard. DO NOT REMOVE ANY PROGRAMS AT THIS TIME! Simply find the listing for the Scan Wizard program, and make note of which version is listed; for example, you might see a listing for Scan Wizard 2.53, or Scan Wizard 5.71, or Scan Wizard Pro. Make a note of the EXACT name of the program, then close the Add or Remove Programs listing.

    Next, follow the SPECIFIC steps on the page that explain how to remove the version of Scan Wizard installed on your system:


    Read through the steps several times BEFORE you begin; doing that will help you understand what is required of you, and should make this entire process much easier to accomplish.

    If you have any questions about the process, SCROLL DOWN TO THE "ADD A COMMENT" BOX NEAR THE BOTTOM OF THIS PAGE, and post them here BEFORE you begin; I will try my best to answer them for you... I want to try to make this entire process as simple as possible, and since I have no way of knowing how much computer experience you have, I took the time to type these detailed instructions. I'm not trying to offend anyone; I'm simply trying to make this as simple as possible for the next person who has a similar problem and finds these instructions...

    Best of luck with this; I'm hoping that your NEXT post here will be to tell me that you've successfully removed the corrupted Scan Wizard files from your system. Once you've done that, you can reboot, then install a fresh copy of Scan Wizard, and test your system.

    Again, use the "Add a Comment" box at the bottom of this page if you have any questions or comments for me BEFORE you begin this repair procedure, and I will try to answer them as soon as possible...

    I just called a former neighbor, because I remembered that he'd had a similar problem with a Microtek scanner. He told me that the instructions on the website did NOT solve his problem, so he contacted Microtek support; they tried to help him, but he eventually gave up and took the system (which was under warranty) back to the store where he bought it, and the in-store technicians fixed the system for him...

    Much as I hate to say it, your problems might require "hands-on" by a technician; if I could drive to Hawaii, I'd be happy to make a housecall for a cup of Kona coffee, BUT, since that isn't possible, you might not have a lot of options to resolve this... you could contact Microtek during the week, because it is possible that one of their techs could guide you through this online, or via a phonecall... I don't think you have much to lose at this point, if removing the ScanWizard software in Safe Mode didn't work... I truly wish I could be of further assistance, but I'd need to roll up my sleeves and get elbow-deep into your hard drive in order to fix this for you...

    Please let us know how things turn out after you contact Microtek...

    Well, we gave it our best efforts, so let's hope Microtek has a better solution to offer you... Please remember to let us know how you resolve this; I'm sure your solution can help others in the future... thanks again for your time and patience; I can only post the advice, you're the one who had to do all the work.

Copystar cs-1815 error code 3200, how can it be fixed

If it is a c-3200 code it means that you have a exposure lamp problem.Defective scanner,defective scanner PCB,lamp or inverter board,incorrect shading,poor contact of the connector terminals on lamp assembly. Look for a bad connection And look at lamp. Look for blue rings or burnt ends. Now don't look at that light while its on.

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,

I have a memorex LCD HDTV 3yrs old, now the set has perfect sound but no picture, just a black screen,

Your LCD lamp may have burnt out or the component usually a driver transistor that drives the lamp to glow may have been defective. Some of LCD have fuses on this section that automatically opens when there was a problem. A qualified electronic service technician could figure out your problem right away if you don't have any experience in electronics troubleshooting.

My mfc240c says to replace the yellow ink cartridge but I don't want to spend money on that if the 'light bulb' is ruined. When I turn on the machine, I don't see any light for scanning or copying. ...

By the "light bulb," do you mean the scanner lamp? That lamp should only turn on when you are actually scanning, faxing, or copying a document. You should be able to still use the machine to scan and fax, even with the yellow ink empty. Try scanning a document to see if the scanner lamp comes on.

As far as printing or copying goes, you won't be able to print or copy anything until you replace the yellow ink, even if you try printing in black and white only.

When it scans it leaves a black line on the document and on the computer screen.

The black line is either caused by dirt build up on the scanner glass (clean the scanner glass) or one of the bulbs on the scanner lamp is burnt out.

Scanner scans but does not see what is on the bed of the scanner. It prints a black page no matter what I scan. Print preview looks like a black page also.

Do you see the scanner lamp come on?

If you do not see the lamp, then the failure may be that the lamp or the power supply for the lamp have been comprised.

Please find a local authorized repair center and have the printer tested and repaired.


When I scan it comes out all black

The lamp in your scanner is defunct and the replacement of these varies greatly and may not be a DIY job depending on the amount of work to access the guts of the scanner. You need to contact Dell to obtain the part number for the lamp and perhaps order it through them; check your owner's guide for the 800 number.

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.


SC101 indicates and exposure lamp problem. To try and correct, turn OFF the copier and then unplug from the wall. Wait 10 seconds and plug it back into the wall, then turn on the copier. Watch to see if the exposure lamp comes on - lift the document handler if you want. If the exposure lamp is working correctly, the scanner will briefly move to the right and the light will turn on then off after it moves to the left.

Scanner scanning blackonly

Look at the lamp to see if it is dim or burned out; if the lamp is defective, you can contact Microtek here: http://support.microtek.com
