• Selectors 1 through 3: Delay time from when documents are set until the ADF starts drawing
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
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: Standby position of the CIS unit
This selector determines whether the standby position of the CIS unit should be the home
position or the location of the white reference film (attached to the inside of the scanner top
cover). If the location of the reference film is selected, the CIS unit will not return to the
home position so as to shorten the travel time, decreasing the preparation time for copying.
• Selector 8: Line polarity reversal detector
When the remote station breaks the connection, a line polarity reversal occurs. Enabling the
polarity reversal detector with this selector allows the machine to detect the polarity
reversal if detected when the user is leaving a message on the station's answering machine.
