NOTE:
WSW45 is applicable only to models equipped with a flat-bed scanner.
l 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.
l Selectors 4 through 6: Periodical correction intervals of the reference voltage applied to white
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.
NOTE:
Do not access these selectors.
l Selector 7: Standby position of the CCD unit
This selector determines whether the standby position of the CCD unit should be the CCD
lock position (home position) or the location of the white-level reference film (attached to the
inside of the scanner top cover). If the location of the reference film is selected, the CCD unit
will not return to the lock position so as to shorten the travel time, decreasing the preparation
time for copying.
