[IDC Sensor Adjustment]
Overview
Use the scanner to correct the IDC sensor and perform gamma correction.
Printer gamma correction is usually done automatically on a regular basis, but changes in the characteristics of the IDC Center may prevent accurate density measurement. Perform [IDC Sensor Adjustment] if the color of output image is not accurate.
NOTICE
- The following setting is required to use this function.
- Perform [Gamma Automatic Adj.].
Tips
- The procedure for making adjustments varies depending on the options installed.
- Use white printing paper for this adjustment. If there is color on the paper, the color of the chart changes depending on that color, and the adjustment cannot be made correctly.
Reference
- For details about [Gamma Automatic Adj.], refer to [Adjustment / Maintenance].
