Calibration Settings
When you set Execute at Every Scan to ON, the scanner will be calibrated every time before
previewing and scanning, to reproduce correct color tones in scanned images.
Note
• Even when Execute at Every Scan is set to OFF, the scanner may be calibrated automatically in
some cases (such as immediately after you turn the machine on).
• Calibration may take time depending on your computer.
