4.1.8 Black - Color Head Vertical Adjustment

This adjustment sets the vertical position for the black and color heads. (Aligning the top nozzle for both, the
# 4 nozzle on the black head and the # 1 nozzle on the color head, and aligning the bottom nozzle for both, the
# 61 nozzle on the black head and the # 20 nozzle of the color head.) Make this adjustment using this
adjustment program and set the Adjustment mode ID = 8 on the control panel (see Section 1.4.5). This
adjustment is required when the black head or the color head is replaced or disassembled. The following
figure illustrates this adjustment.
Figure 4-13. Black - Color Head Vertical Adjustment
When you replace the black head, always adjust its angle first, because the black - color head
vertical adjustment is based on the black head angle.
