Hi Rasha,

ADF backside scanning optical alarm (upper optical unit ADF) is E3 alarm. When there is an irregularity in the amount of light (ADF back), "E" and "3" will be displayed alternately on the function number display panel of the scanner.

Please check the followings:

1.Does the same symptom occur after turning OFF and ON the scanner?
2. Is the lower glass (white sheet guide) of the reading section dirty? Open the ADF, and clean the sheet guide (white part) and the glass.
3. Is the upper Optical unit ADF dirty? Are the cables damaged? Are the connectors connected properly?
4.E3: Is the upper lamp ON? Are the cables damaged? Are the connectors connected properly? Disconnect the SCSI cable and turn the scanner ON. Open the ADF and press ADF cover open sensor as shown below to see if the ADF lamps light which has to be replaced.

I would recommend to contact an authorized FUJITSU scanner service provider or the dealer where you purchased the scanner.

Hope the above information is helpful.

Thanks & regards,

Bad exit sensor. Either replace sensor or time to get a new scanner.

Mine came with the same error message. If you look through the glass into the left front corner, you should see a spring loaded belt tensioner device. It merely hooks into the bottom plate against a spring to keep the belt tight. On my 5750C, the belt tensioner had slipped out of the base during shipping. The hardest part of inserting it back into the base was getting to it. Directions to do that are on this site at .../support/t484836-taking_apart_flatbed.

MAY SCSI CONNECTOR`S PIN PROBLEM IN FLATE BED SCANNER UNIT

I can only help with the code,P0031=Shorted low condition detected in the oxygen sensor,1/1 heater element control feed back sense circuit.
Also a web site which gives the code breakdowns-www.wjjeeps.com/faultcodes.htm.

Need to replace exit sensor

If "Front Side Optical Alarm" appeared, clean the glass (small and large one) of the flatbed and carrier unit.
If the issue persists, then check if CCD harness or CR cable is disconnected? Connect the connector.
If the issue persists, then replace Front lamp.
If the issue is not resolved, then replace the Control PCA or Carrier unit or Optical unit.

See page 25 of:

"E2" is "Trouble with the optical system (front)."

That doesn't solve your problem, but at least it narrow downs the focus of your problem.

Hi,

The scanner does self-diagnostic when receiving Read Command (to start scanning) and displays the result if any error or alarm is detected.

Error code-E3 in Fi-4120c2 scanner means "Light intensity check" . When this error is displayed on the scanner panel, TWAIN displays the following error-

" Irregular status is detected in scanner. If this status recurs after power cycling, please give following Sense key and ASC code to your service provider.
If ASC code is the following, please confirm following status before power cycling’
- When ASC=0x580, confirm if the shipping lock (if any) is set at “Release” position.
- When ASC=0x680, clean the sheet guide (white part) in ADF.
(Error Code DS42001)

E3 explains Optical alarm (back). This alarm occurs if the gain adjustment of the CCD amplifier does not succeed at a READ command for the first document, or during scanning.

Probable causes:
- The lamp, the optical system or white sheet guide is dirty.
- Defective lamp or CCD.
- Connector disconnected

To check and resolve the issue, lease follow the steps provided below:

1. Is sheet guide (white part) in the reading position dirty?
#Open the ADF and clean the sheet guide (white part) and the glass.
2. Is the lamp ON?
3. Are the cables damaged?
4. Are the connectors connected correctly?
#Disconnect SCSI cable and turn the scanner ON. Open the ADF and press Cover open sensor to see if the lamp lights. If not, the error is caused by the defective lamp.
5. Is the optical unit dirty?
6. Are the cables damaged?
7. Are the connectors connected correctly?
# Check and Clean (ADF back):
# Check if inside of the grass for Upper unit ASSY is dirty. Clean inside of the glass of the dust cover.
9. If the issue still persists, then you may have to replace Optical unit.

Hope the above information will be helpful.

Please revert if you have further queries.

Thanks & regards,
