• Selectors 6 through 8: Effective time length of the white level compensation data obtained
If you set documents in the ADF and the document front sensor detects them, the controller
will make correction of the reference voltage to be applied to white level compensation for

These selectors determine how long compensation data obtained beforehand will keep
