Troubleshooting

Bad/no gray balance calibration (CIS module to module

match).

Scanning originals that have folds or is crumpled on a CIS scanner is often taken as a

defect on the scanner, where it is actually a limitation of the used technology. Due to the

very short distance from sensor to surface of the original, also called “Focal Length” we also

have a very short “Focus Depth” meaning, if the original is NOT in contact with the glass

plate it is very likely to be out of focus!
