Procedure B
Shading Co-efficient Adjustment in SP Mode
As explained on the previous page, shading co-efficient adjustment in the SP mode is
done manually for each area and could be somewhat complicated. You may want to take
note of the following before carrying out this procedure.
• Adjustment will take approx 1 hour for each color.
• Necessary tool: Ruler longer than 165 mm
• If the shading co-efficient has to be reset to the default value, do SP2108-001/002,
turn the main power off/on, and do SP2111-004 (full MUSIC process).
1. Set the value in Skilled Operators Menu #0205 to “0”.
2. Turn the main power off/on.
3. Print the test pattern on the largest paper in use by the customer.
SP2109-003 26. Full Dot Pattern
SP2109-005 Black, Magenta, Cyan or Yellow
SP2109-006~009 5
4. Check the density at the top and bottom edges. Then, fold the paper in half along the
feed direction, and make measurements at two locations X and Y in millimeters as
indicated in the diagram below
