Calibrating the scanner
With time, the scanner colors detection tends to change to incorrect values. This
phenomenon affects the text detection accuracy as well as the resulted image quality.
To reset the scanner to the proper colors, the scanner needs to be calibrated.
How to calibrate?
To calibrate the ScanShell 800scanner, insert the calibration paper card that was part
of the scanner package into the scanner, and click on the Calibrate button (located in
the configuration panel’s Image tab). The ScanShell 1000 does not require a
calibration paper, just click on the Calibrate button.
Cleaning the scanner
Cleaning the scanner improves the scan quality.
To clean the scanner click on the “Clean Scanner” button. Follow the Cleaning
Wizard instructions. This operation requires a cleaning sheet (supplied with the
scanner) and alcohol solution.
