Fix Fujitsu ScanSnap SV600i Error E-203: Lighting

The Fujitsu ScanSnap SV600i error E-203 is triggered by light intensity issues. Because this is an overhead device, ambient lighting has a direct impact on the image sensor calibration. If the sensor detects too much or too little light compared to its baseline, it throws this error.
