● Change of Magnification Ratio
The scanner performs reading at 600 dpi or 300 dpi. For the color mode, only COLOR mode is used; the scanner does not perform
reading in B&W mode scanning regardless of the color mode selected in the Control Panel.
When configured to read in black and white, the controller converts the mode to black and white to perform processing.

● Color Displacement Correction Processing in Vertical Scanning Direction
Color displacement correction control in the vertical scanning direction is used to correct displacement of R, G, and B by shifting
the pixels in the vertical scanning direction (by less than 1 pixel) to align the red and blue images with green when the scanned
R, G, and B images are not accurately overlapped at color scanning.
Example: A scanned image of a black line where red is displaced upward and blue is displaced downward with respect to green

As for the color displacement correction value in the vertical scanning direction, there are two types of reader scans as shown
below. Color displacement in the vertical scanning direction is adjusted beforehand at the time of shipment, and those correction
values are stored in service mode. (Refer to the following related service modes.)
