• Selectors 1 through 4:Change rate of the CCD light intensity for scanning pages
compensation (Not used.)
The light intensity of the CCD unit may be changed (decreased, especially), and difference
of density may appear among the scanning pages if continuous copying or scanning is
implemented from the ADF for a long time. To prevent the above, in simplex copying or
scanning from the ADF, the machine checks the change rate of the light intensity in every
page. Then, it takes the compensation data again if the rate is over the set value. These
selectors set the change rate of the light intensity to control such operations.
Change rate for simple compensation:
Change rate when compensating the pages using the standard data in the machine
memory without moving the CCD unit to the designated position for scanning of the
compensation data.
Change rate for regular compensation:
Change rate when compensating the pages with moving the CCD unit to the designated
position for scanning of the compensation data and obtaining the data actually.
For duplex scanning, this setting is not used since the machine takes the compensation
data of every page again.
