Overall Check
1. After you do the color registration error and color skew corrections, do a forced
MUSIC again, with SP 2111 001.
2. Do SP 2109 002 and print pattern 1 (1-dot line) on A3/DLT paper again. Check
the skew and color registration. If they are still not acceptable, do the forced
MUSIC again.
3. Do SP 2181-030 to make sure that the forced MUSIC was done correctly. If the
result is ‘1’, then each color was aligned correctly.
If "1" is not shown, then please see section 4.2.1.
