Color Balance Adjustment
This procedure will allow you to adjust the balance of your printer by
changing the densities of the four toners (black, cyan, magenta, and yellow).
Because this procedure adjusts the parameters within your printer
hardware, it will affect all print jobs.  
CautionThis procedure changes the color balance of your printer by altering
developer bias and laser power.  It will affect all print jobs.  Do not perform
this procedure before exhausting recommended troubleshooting options.
Do not perform the color balance adjustment procedure until all of the
following troubleshooting methods have been completed:
1Experiment with driver and software application settings to adjust the color
output.  
2Complete the cleaning procedure on optics, transfer corona, and drum
corona.  See “Regular Printer Maintenance” in Chapter 6. 
3Complete the troubleshooting solutions in Chapter 7 for the color printing
problem you are experiencing.

							Adjusting Color Balance
CautionAdjusting the color balance will change your printer hardware.  Perform all
of the troubleshooting methods listed above before attempting the following
procedure.
1Print a self test page.
See Chapter 5 for instructions on printing a self test page.  The self test
page will display the last set of saved color settings and provides a record of
your initial settings before any adjustments.  The factory setting for each
color is 0 (other possible settings include -2, -1, 1, and 2). 
2Turn the printer off.
3Print a color balance test page:
While holding down the [Menu] and [Enter] keys on the front panel, turn the
printer back on. The printer display will read, “Color Balance Test Page.”
(If this is not shown in the display, press the [Item] key until it is.)  Press the
[Enter]  key to print the Color Balance Test Page. The test page will consist
of two color bars (black and cyan) and a box of color balance circles (see
Figure G-1).
4Adjust the black (K+/K-) density setting.
Examine the black bar from a distance of 6 feet (2 m).  If the two center
arrows (Figure G-2, callout 1) blend into the background of the black bar the
black density does not need to be adjusted (continue with the cyan setting).
If one set of arrows (left of center or right of center) is more visible on the
black bar, do the following: 
·Press the [Item] key to get the K density display. 
·If the four arrows on the right (Figure G-2, callout 2) are more visible, the
density needs to be increased.  Press the [+] key once.  
·If the four arrows on the left (Figure G-2, callout 3) are more visible, the
density needs to be decreased.  Press the [-] key once.
·Press the [Enter] key when finished.

							Adjusting Black and Cyan Density Settings
5Adjust the cyan (C+/C-) density setting.
·Press the [Item] key to get the C density display.
·Repeat the last three steps in 4, this time using the cyan bar.
6Reprint the color balance test page.
Press the [Item] key until “Color Balance Test Page” is displayed on the front
panel.  Press the [Enter] key.  A new test page will print.  Examine the black
and cyan bars.  If the two center arrows blend into their respective
backgrounds, go to step 10, otherwise repeat steps 4 and 5 (the maximum
color density setting is +2 and the minimum is -2).

							Adjusting Magenta and Yellow Density Settings
7Adjust the magenta and yellow density settings.
Examine the color balance circles from a distance of 6 feet (2 m).  If the
center circle (Figure G-3, callout 4) blends into the background, the magenta
and yellow densities do not need to be adjusted (go to step 9).  Determine
which circle blends in best with the background.  Make note of the magenta
(M) and yellow (Y) density adjustments (for example, M+, Y+ for Figure G-3,
callout 5) for that circle. 
·Press the [Item] key to select M Density.  Press the [+] key once or the [-]
key once to increase or decrease the M density value.  Press [Enter] when
complete.
·Press the [Item] key to select Y Density.  Press the [+] key once or the [-]
key once to increase or decrease the Y density value.  Press [Enter]  when
complete.
8Reprint the color balance test page.
Press the [Item] key until “Color Balance Test Page” is displayed on the front
panel.  Press the [Enter] key.  A new test page will print.  Examine the color
balance circles.  If the neutral gray circle is in the center go to step 9,
otherwise repeat step 7.
9Press [On Line] to continue.  
The maximum density setting is +2 and the minimum is -2.
