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 or if you open the
document tray ASSY and the document tray open sensor detects the open state, then the controller
will make correction of the reference voltage to be applied to white level compensation for
document scanning before the Copy button is pressed.
These selectors determine how long compensation data obtained beforehand will keep effective.
