Adjustment procedure
1. Copy a C-4 chart in text mode. Compare the copy with the chart.
2. Enter SP mode.
3. Open SP 4-XX-X for text mode (see the above tables for the SP numbers).
4. Adjust the offset values until the copy quality conforms to the standard. (The
diagrams at the end of this procedure explain the ID ranges affected by each
setting.)
5. Copy a C-4 chart in photo mode. Compare the copy with the chart.
6. Open SP 4-XX-X for photo mode (see the above tables for the SP numbers).
7. Adjust the offset values until the copy quality conforms to the standard.
8. Copy the C-4 chart in auto text/photo mode.
9. Examine the photo part (lower half of the image) on the C-4 chart. Compare the
copy with the chart. Proceed to the next step if color displacement errors are
found. Terminate the adjustment if the check proves normal.
10. Adjust the offset for low ID within the range of +_2.
