How to perform white balance calibration?

The method and steps for calibrating white balance are as follows:

1. Take out the gray card from the case and position it face-up on a light-color surface.
2. Select the “White Balance Calibration ” function on the left, and process the calibration following the on-screen instructions, as shown in Figure 6-3.
3. Align the scanner perpendicularly to the gray card surface, adjust the distance until the position indicator enters the yellow target frame on the user interface.
4. Maintain a vertical standoff distance of 300 mm between the scanner and the gray card.

Note: In which situations is white balance calibration required?

• Environmental Change Between Scans (e.g., outdoor-to-indoor transition).
• Color Deviations (e.g., significant hue/saturation deviation during real-time preview)
• Complex Ambient Lighting (e.g., Mixed artificial light sources (e.g., red/green dominant illumination)
