Selectors 1 through 3:Delay time from when documents are set until the ADF starts
drawing them in
These selectors determine how long the ADF will delay automatic drawing-in of documents
(to the scanning standby position) after you set them in the ADF, as well as determining
whether or not the ADF automatically draws in documents.
Selectors 4 through 6:
Periodical correction intervals of the reference voltage applied to
white level compensation for document scanning, during standby
These selectors set the correction intervals (in seconds) of the reference voltage to be
applied to white level compensation for document scanning during standby, as well as
determining whether or not the controller makes the reference voltage correction during
standby.
(Conventionally, the correction has been made immediately before the start of
actual scanning)
This function takes effect in copying.
Making the correction during standby may shorten
the preparation time for copying.
