Adjust the color density at each of the 15 points for each of the four colors.
NOTE: 1) Execute these to decide what density value to input:
2) Look at the color adjustment sheet.
3) Look at the gradation scale entitled 'Default' for the color you want to
adjust.
4) Go along the scale until you reach the density you want to input.
5) 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.
6) Execute the same for all 15 points.
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. Do the adjustment again if
there is an anomaly (normally, repeat this procedure 3 to 5 times).
11. Execute these when the adjustment results are satisfactory:
1) Use Controller SP 1105 "ToneCtlSave" in the controller service menu, to
store the new settings in the controller.
2) Reset the controller (press the [Reset] key when the machine is off line") to
use the new settings.
NOTE: You must reset the controller to keep the new settings in the controller
NVRAM.
