DADF 2 faces color differ crrct (back)
To acquire scanning data on the back side in order to correct the color difference between the front
and back side at the time of duplex stream reading.
A significant color difference may occur between the front and back side of the image scanned on
DADF caused by variations in the LED and changes in durability. Such a color difference is
corrected by executing 1PSCLB-B following 1PSCLB-A.
When a significant color difference occurs between the front and back side at DADF duplex reading
1) Set the document used by 1PSCLB-A on DADF, so that the front side is faced down and the
cyan image is placed at the left rear side.
2) Select the item, and then press OK key.
Do not turn OFF/ON the main power switch before executing 1PSCLB-B even though OK is
displayed by 1PSCLB-A.
During operation: ACTIVE, When operation finished normally: OK!
