NOTE: WSW45 is applicable only to models equipped with a flat-bed scanner.
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
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.
Selector 7: Home position of the CCD unit
This selector determines whether the home position of the CCD unit should be the CCD lock
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.
