Note on White level adjustment 08
If you want to perform “White level adjustment” for Flatbed with a “Black document holding pad” installed onto
the scanner, replace it with the standard “White document holding pad” before starting the adjustment.
If you cannot install the standard “White document holding pad”, pile up three white reference sheets and close the
“Black document holding pad”, and then start adjustment.
* If White level adjustment is performed with a “Black document holding pad” installed, the correct offset may
not be acquired which results in abnormal image (the image is too bright).
