NOTE:
Selectors 6 through 8 are applicable only to models equipped with ADF units.
Selectors 6 through 8: Effective time length of the white level compensation data obtained
beforehand (Not used.)
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 document
scanning before the
Copy
key is pressed.
These selectors determine how long compensation data obtained beforehand will keep effective.
