4. Replacement and Adjustment
• When you look at the printed pattern, the number sequence of the CIS joints is reversed, with CIS-5
on the left through CIS-1 on the right as shown in the diagram above.
• After completing the CIS adjustments, be sure to reset SP4973 to "2".
To Adjust the Image at the CIS Joints
1. Check the printed pattern to determine if the dots are aligned at CIS 1-2.
2. If they are aligned correctly, no adjustment is necessary.
-or-
If they are not aligned correctly, do the next step. Here are two samples where the outputs are not
aligned correctly.
• [A]: Distance between the lines at CIS 1-2 is wider than usual (as shown above). If the
distance between these lines is wider or narrower than the other lines, adjust the main scan
offset at CIS 1-2 with SP4972-1 (CIS Joint Adjustment –CIS 1-2 Main Scan) as described
below.
• [B]: The lines at CIS 1-2 are broken. If the output from CIS 1 is lower (as shown above) or
higher, adjust the sub scan offset at CIS 1-2 with SP4972-6 (CIS Joint Adjustment – CIS 1-2
Sub Scan) as described below.
To adjust the main scan offset for Example [A]
Problem: Output from CIS 1 is too far to the right.
1. Do SP4972-1 and adjust the setting.
• Adjust the position of CIS 1. The position of CIS 2 does not move.
• If the area at the joint is too wide, set a smaller value.
• If the area at the joint is too narrow, set a larger value.
