Adjust the color density at each of the 15 adjustment points (default values 16
to 240) for each of the four colors.
NOTE: To decide what density value to input, do the following.
1) Look at the color adjustment sheet.
2) For the color you are adjusting, look at the gradation scale entitled
"Default".
3) Go along the scale until you reach the density that you wish to
adjust.
4) Read off the value on the scale and store it in the machine.
a) Use the up/down key to move the cursor along the three-digit
display, then press the Enter key.
b) Use the up/down key to change the digit at the cursor, then press
the Enter key.
c) Press the Escape key to exit from the menu.
5) If necessary, repeat this procedure for all 15 adjustment points for
each color and black.
10. When the density setting is complete for all colors, print out a color adjustment
sheet again and make sure that the gradation scale for each printed color is
smooth and that the CMY gradation scale is gray. Repeat the adjustment if
there is an anomaly (normally, repeat this procedure 3 to 5 times).
NOTE: Adding a new value (0 to 255) to any of the adjustment points will not
change the calibration sheets scale. In other words, the density value
entered for any adjustment point is not shown numerically on the gradation
scale.
11. When the adjustment results are satisfactory, do the following:
1) Use "SP1105 ToneCtlSave" in the controller service menu, to store the new
settings in the controller.
