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, a white banding problem may occur, or the color head timing may
not match the black head timing. The following figure illustrates the black head angle adjustment.
The black head angle is adjusted with linear and angular spacers. A linear spacer is attached to both
sides of the head base, and an angular spacer is attached only to the right side of the head base.
Spacers for the black head come in different shapes for the thickness needed. The following figure
shows the relationship between the shape and thickness.
