Control detail
1) DC Controller creates the patch pattern of each color on the ITB.
2) DC Controller compares the patch pattern with the standard value backed up in the
DC Controller by reading this patch pattern at the Patch Sensor and detects the color
displacement amount.
3) Based on the foregoing detection result, the laser emission position (tilt degree) of Laser
Scanner Unit is changed.
