There are 2 sensors on the background unit(Front) SF1.5 and SF 2
Both sensors look like black boxes. SF2 is nearest the reading glass and SF1.5 is below it. Make sure both are clean. There are also tests you can run in test mode to recalibrate the sensors, if that doesn't work you have to replace it.

Hi, Is the code display L-6? This error code describes US Sensor Alarm. You may perform the following steps or may ask your local Fujitsu scanner expert for the disgnosys and replacement of faulty part. 1. Does the same symptom occur after turning OFF and ON the scanner? To check, press power button of the scanner for more than 2 seconds to turn it OFF, and after more than 2 seconds elapse, press the power button to turn the scanner ON. 2. Check the US Sensor operation by conducting Maintenance mode to see if the US sensor works properly. If the error still occurs, confirm that the sensor cable is correctly connected. And then replace the US Sensor FX and US Sensor RV. Thanks & regards, ScanCare
In Fujitsu fi-5900c scanner, Error 05a refers to JAM1 Sensor malfunction.You need to clean the two lenses of the JAM1 sensor with a cotton swab. Then check the performance of the sensor and also check sensor cable connections. This error also occurs if Pinch Roller 2 is installed left-right reversal. Check the same too. If the issue still persists, then you may have to replace the sensor.
If the above steps do not help, then you are recommended to contact the nearest Fujitsu service center for assistance.
Thanks & regads,
When you face such errors, please check if the Scanner panel displays-"E-0" and TWAIN displays- “The running system is abnormal. Please confirm the carrier lock has come off.”
The error is Carrier unit drive alarm. After power-on, carrier unit (FB) moves to home position, that is where the carrier unit locates when home position sensor is turned ON. If the home position sensor is not turned ON after the carrier unit has moved pre-defined steps, this error occurs.
Probable causes: Defective sensor, motor, or carrier belt.
Also, please check the following:
1. Is there is any abnormal noise from FB motor when this error occurs? 2. Does any foreign object get inside drive unit or carrier unit? 3. Is CR belt tension loose? Loose belt should be tightened.
