AR-P16  COLOR BALANCE ADJUSTMENT  9 - 1

The printer color balance adjustment is used to manually adjust grada-
tion of Cyan, Magenta, Yellow, and Black in each level of low, medium,
and high density.

The color balance adjustment in the printer mode is generally per-
formed by the user. However, a serviceman can perform this adjust-
ment more accurately by use of the test chart for servicing.

As the printer is used, ambient conditions and the depletion of consum-
ables (the toner cartridge and drum cartridge) can gradually cause
changes to occur in the four color components of color images, cyan,
ma-genta, yellow, and black. This results in deviations in the color bal-
ance.

These deviations in the color balance occur gradually over a long
period of time. Ambient conditions (tem-perature and humidity) and the
number of times the printer is used can have a large effect on color
devia-tion.

The printer has two color adjustment functions for the purpose of cor-
recting deviations in the color balance.

These functions are executed from the key operator programs.

Be sure to perform this adjustment when consumable part is replaced.

For execution of this adjustment, the print engine section must be in
the normal condition. (All the adjustment items related to the print
engine section must have been adjusted properly.)

The printer has the following two color balance adjustment functions:

This function is used to adjust each of the density levels (low, mid, and
high) of the four color components, cyan, magenta, yellow and black. 

Use this mode when the color deviation is large.

This mode is used for fine adjustment of the gray balance at the mid
density level of the colors cyan, magenta, and yellow.

Use this mode to correct minor color deviations.

Test print: Used to check the current color balance and the gray level
adjustment state. By executing this adjustment, the test page is
printed.

Cut off the sections between two rows of the test pattern as shown
below cutter.

1) Enter the key operator program mode. 

2) Select "Printer setting."

3) Select "Color adjustments."

4) Select "Color balance setting."

5) The display below is shown. Select A4 or 8.5" x 11" size paper,

and press the EXECUTE key.

The test pattern for adjustment is printed, and the adjustment
menu is displayed. 

Test pattern

(Note) Use paper of the same or nearest color as the background color

of the test chart (UKOG-0305FCZZ) as far as possible.

6) Collate the test chart (UKOG-0305FCZZ) and the test pattern

patch density.

Place the test chart on the printed pattern so that the printed pat-
tern can be seen from the cut sections. Put several sheets of white
paper beneath the printed pattern.

Find out the density point in the test pattern array 1 which lies
between the Lower Limit and the Upper Limit of the test chart (1).

Put a check mark on the density point found in the procedure
above.

If there is no density point which satisfies the above condition in
test pattern array 1, perform the following procedures.

• When the test chart (1) density is higher than the maximum den-

sity (+4) in the array 1:

→

 Put a check mark on "+4" in the array 1.

• When the test chart (1) density is lower than the minimum den-

sity (–4) in the array 1:

→

 Put a check mark on "-4" in the array 1. 

For densities of Test chart (2) to (12), perform the same procedure
as procedure 6).

7) Set the adjustment points (+4 to –4 on the right side) correspond-

ing to the density points (12 positions) marked with check mark on
the test pattern on the adjustment menu.

• Use the 

 and 

 keys to select the color (Y, M, C, or Bk) in

“LOW AREA”, “MIDDLE AREA” or “HIGH AREA” that you wish
to adjust.

• Use the 

 and 

 keys to select the density level (+4 to –4)

that matches the density level in the standard color chart.

• Use the
