Determining the Adjustment Values
The Color Registration Chart is used to adjust the color registration.
The following explains how to determine the adjustment values.
On the Color Registration Chart, find the straightest line where the two black lines and the
colored line are most closely aligned for each color (Y, M, and C). If you find the straightest
line, make a note of the value (-9 to +9) indicated by the straightest line for each color.
When the value is "0" for each color, you do not need to adjust the color registration.
When the value is not "0", enter the value using the procedure in "Entering the Adjustment
Values" (P. 140).
On the following condition, move to up the value:
• Toner scatters around images.
• Images is turned to bluish color.
On the following condition, move to down the value:
• Output is too light. (faded or unclear)
Entering the Adjustment Values
Set the adjustment values that you have identified in the Color Registration Chart using the
control panel.
The values can be entered within the range of -9 to 9 in increments of 1.
Note
• By default, the adjustment values of all colors are set to "0".
