On the device, turn off the power. Lift up the top where the cartridges are and flick the little green switch underneath to the right front corner. I don't know what these parts are called, but this worked for me.

I have the message "Unlock scan head" when I turn the screw to the left to unlock it, I get the same message. Is there anything else I should be doing?


If you receive this error even after unlocking the scanhead xerox suggests replacing the scanner assembly. Item Inc offers this part on exchange for much cheaper then xerox. Here's a video to show you how to fix this error/replace the scanner.">

My 5800 keeps telling me to unlock it when I click scan, but I can't find the lock anywhere.


The 5800 scanner does not have a physical lock switch. DO NOT attempt to open the scanner and unlock the hardware. This could be either a hardware failure or software
Toggle the lock switch on the scanner leaving the switch in the unlocked (open padlock) position.
Ensure you are using the correct power supply for your scanner. If you are using a power supply that has the incorrect DC output, you will get a scanner locked error message. This flatbed scanners has I believe 100-120V AC input and 12V DC output.


Plug the power directly to the wall, not a UPS battery back-up, power strip or surge protector. Power fluctuations from a UPS battery back-up, power strip or surge protector may be causing this error. If all this fails try reinstalling the scanner driver

Fi-4120c2 error Code


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,
