* Execute the half-tone image correction forcibly. (SIM 44-26)
(Method)
Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy
of the servicing color test chart (UK0G-0283FCZZ), and check that
they are proper.

a. Note for execution of the color balance and density check in
the color copy mode
To check the copy color balance and density, use the gray test
chart (UKOG-0162FCZZ) and the servicing color test chart (UK0G-
0283FCZZ). Set the copy density level to "3" in the Text/Printed
Photo mode (Manual), and make a copy.
At that time, all the color balance adjustments in the user adjust-
ment mode must be set to the default (center).
In addition, be sure to use the specified paper for color.

In addition, be sure to use the specified paper for color.
b. Note for checking the monochrome copy mode density
To check the density, use the gray chart (UKOG-0162FCZZ). Set
the copy density level to "Manual 3" in the Text/Printed Photo mode
(Manual).
In addition, all the color balance adjustments in the user adjustment
mode must be set to the default (center).
• Check with the gray test chart (UKOG-0162FCZZ)
In the copy density check with the gray test chart, check to insure
the following conditions.

• Check with the gray test chart (UKOG-0162FCZZ)
In the copy density check with the gray test chart, check to insure
the following conditions.
NOTE: For the color (gray) balance, use the servicing color test
chart (UKOG-0283FCZZ) to check.
(5) Printer color balance (see ADJ 21)
Before checking the copy color balance and the density, be sure to
execute the following procedures in advance.
* Execute the high density image correction (process correction)
execute the following procedures in advance.
* Execute the high density image correction (process correction)
forcibly. (SIM 44-6)
* Execute the half tone image correction forcibly. (SIM 44-26)
a. When the PCL mode is supported:
Execute SIM 64-5 to print the print test pattern.
Set each set value to the default and press [EXECUTE] key. The
print test pattern is printed.
The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.

b. When the PCL mode is not supported: (In the case of GDI
model)
Use SIM 67-25 to print the color balance adjustment sheet and
compare each process (CMY) black patch color balance and the
black patch to check the color balance.
The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed.
The density level of each color must be almost at the same level.
Patch B may not be copied.
Patch A must not be copied.
Check that the above items are normal. If not, make the adjust-
ment.
