4.1.4 Black Head Angle Adjustment
The black head angle adjustment is required when the black head is replaced or disassembled. If
this adjustment is not correct, the white banding problem might occur or the color head timing
might not match the black head timing. The following figure illustrates the black head angle
adjustment.
The black head angle is adjusted by the linear spacer and the angular spacer. The linear spacer is
fixed to both sides of the base head, and the angular spacer is fixed only to the right side of the base
head.
