Color Balance Sample—Sampling the Color Balance
Adjusting the color balance by trial and error could require many copies. The color balance sampling function
allows you to produce nine samples on two copies. The first sample of each sheet uses the current color
balance (standard). Each sample after that changes one toner color by a fixed number of steps.
Note
❐The sample will be copied on two A4p, 81/2" ×11"p sheets or two A3l, 11" ×17"lsheets.
❐Selecting Color Balance Sample does not reset the adjustments, allowing you to make many samples while
progressively changing the balance. The sample might yield a color balance outside the copier’s range which will be
reproduced on the sample but not on the copy.
For example, if yellow is already adjusted to +3 and you select Sample ±4, the yellow samples will be copied at yellow
+7 and –1, but the adjustment for the final copy cannot be set to +7.
❐The sampled area is as shown in the illustration.
❐If your machine is Edit type, you can select the sampled area. ☛See page 128.

❐Default: level 5
❐If copying a newspaper or an original with a dark background, adjust the background
density to a lighter setting.
❐If part of the original is marked with a highlighting pen, adjust the background density
to a darker setting. However, because the color of a highlighting pen is difficult to
duplicate, it might be copied in different colors or some colors might not be copied.
You can make copies in pastel tones.
Reference
❐For copy samples, ☛see page 20.
Note
❐Default: level 9 which yields a normal color copy
You can adjust the black toner density to make the black parts clearer in Full Color mode.

You can adjust the sensitivity when detecting whether the original has color areas in
Auto Color Select mode. When set to “B&W” values, the machine will be more likely to
detect originals as black originals. “Full Color” values will cause the machine to be more
likely to detect originals as color originals.
Note
❐Default: level 3
You can adjust the sensitivity when detecting letter and photo parts of an original in Text/
Photo mode. If letter parts photo parts of an original are not differentiated correctly, adjust

Color sample chart, ☛see page 23.
If your machine is Edit type, you can sample the user color. ☛See page 138.
Note
❐There are two ways to make user colors as follows:
•Adjusting a selected base color
•Mixing colors manually with Number keys
❐Up to 15 colors can be stored.
❐The total percentages of the mixed colors must be 255% or less.
❐If the total percentage of the mixed color is over 255%, the copier cannot create the color properly and the results will
appear different.
❐If the total percentage of the mixed colors is too low, it may not be bonded to the paper properly resulting in a change
in image density.
❐The appearance of user colors might vary slightly according to the image type you have selected (ex. Photo, Text,
etc.).
