4.1.6 Color Head Angle Adjustment
The color head angle adjustment is required when the color head is replaced or disassembled.
If this adjustment is not correct, the white banding problem occurs or the black head timing will
not match the color head timing. The following figure illustrates the color head angle adjustment.
The color head angle is adjusted by the angular spacer. The angular spacer is fixed to only left side
of the base head.
