Color Density Adjustment - Panasonic DP-CL18 Service Manual

11.2. Color Density Adjustment

This adjustment is used to set the density of the toner applied to the media.
This feature compensates for the changes in density that can occur as environmental conditions change, print cartridges or the
accumulator unit age.
1. Print a Color Calibration Test Print Page using the Calib. Test Prn. of Color Calibration menu in the user mode (see section 4.7).
The current density setting for each color is indicated by the line enclosure on the Color Calibration Test Print Page as shown
in the following example.
The factory default setting for each color density is 0.

* CMY Composite Gray is the color mixed cyan, magenta and yellow.
If the color calibration is proper, the CMY Composite Gray is near gray.
2. Compare the current color density settings on the Color Calibration Test Print Page with the color density samples on the Color
Calibration Card to see if they match.
Place the Color Calibration Test Print Page on at least 2 sheets of clean white paper in a well-lighted area.
