Ricoh Aficio SP C440DN Field Service Manual page 253

Adjust the color density at each of the 15 points for each of the four colors.
• Do these to decide what density value to input:
• Look at the color adjustment sheet.
• Look at the gradation scale entitled "Default" for the color you want to adjust.
• Go along the scale until you reach the density you want to input.
• Read off the value on the scale and store it in the machine:
• Use the up/down key to move the cursor along the three-digit display. Then press the Enter
key.
• Use the up/down key to change the digit at the cursor. Then press the Enter key.
• Press the Escape key to exit from the menu.
• Do 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. Do these when the adjustment results are satisfactory:
• Use Controller SP 1105 "ToneCtlSave" in the controller service menu, to store the new settings
in the controller.
• Reset the controller (press the [Reset] key when the machine is off line) to use the new settings.
• You must reset the controller to keep the new settings in the controller NVRAM.
