Used to enter color shift compensation value in sub-scanning
direction (between R and G/G and B for document reading
dependent on CCD unit + lens).
- If you have cleared the reader controller PCB's RAM or replaced
the reader controller PCB, enter the value on the service label.
- If you have replaced the CCD unit, enter the value on the label

-1000 to 1000 (Value at time of factory shipment: Factory-
measured value)
(Value after RAM clear: 0)
Of the color shift in the sub-scanning direction generated by the
read optics, the amount dependent on the CCD unit + lens is
compensated by adjusting the 3-line CCD sensor's compensation
amount between R and G.
Image compensation is performed by image processing by the main
controller PCB.
T-18-47
Used to enter the color shift compensation value (during normal
reading in color mode) in the sub-scanning direction.
- If you have cleared the reader controller PCB's RAM or replaced
the reader controller PCB, enter the value on the service label.
-1000 to 1000 (Value at time of factory shipment: Factory-
measured value)
(Value after RAM clear: 0)
During normal reading in color mode, the color shift in the sub-
scanning direction due entirely to the reader unit is compensated by
adjusting the 3-line CCD sensor's compensation amount between R
and G/G and B.
Image compensation is performed by image processing by the main
controller PCB.
