■ Color displacement correction processing in vertical scanning direction
Color displacement correction control in vertical scanning direction is a processing to correct the displacement in RGB by shifting
pixels in the vertical direction (up to 1 pixel) to align GREEN with RED and BLUE images when RGB cannot be read such that
they are accurately overlapped at color scanning.
Example) Scanned image of black line when RED is shifted upwards and BLUE is shifted downwards compared to GREEN

There are 2 color displacement correction values in the vertical scanning direction, as indicated below. The correction values are
already adjusted at the time of shipping and stored as service modes. (In COPIER > ADJUST > CCD)
• COPIER > ADJUST > CCD > 100-RG
• COPIER > ADJUST > CCD > 100-BG
When a job is started, color displacement correction processing is performed based on the saved color displacement correction
values.
