10) Check the copy color balance and density.

There are two methods to check the color balance and density.
(Method 1)
Use the servicing color test chart (UKOG-0317FCZZ/UKOG-
0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy color balance and density. (Refer to the item of the
copy color balance and density check.)
(Method 2)
By printing the color balance adjustment sheet with SIM 46-21
and comparing each process (CMY) black patch color balance
with the black patch, the color balance adjustment can be
checked more precisely.

If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color cor-
rection table in an actual copy mode. (When the color balance
target is DEF 1.)
If the automatic adjustment cannot obtain satisfactory results
of the copy color balance and density, use SIM 46-21 (ADJ
20C) (Manual adjustment).

11) Check the printer color balance and density.

There are two methods to check the color balance and density.
(Method 1)
Use SIM 64-5 to print the print test pattern and check the print
color balance and the density.
Set each setting value to the default and press [EXECUTE]
key, and the print test pattern is printed.
(Refer to the item of the printer color balance and density
check.)

(Method 2)
Use SIM67-25 to print the color balance adjustment sheet and
compare the black patch color balance of each process (CMY)
with the black patch. This procedure allows checking the color
balance adjustment result correctly.

If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color table
in an actual printer mode. (When the color balance target is
DEF 1.)
If a satisfactory result on the print color balance and the den-
sity is not obtained with the automatic adjustment, execute the
manual adjustment (SIM 67-25) (ADJ 21B).

Check that the following operations are normal.

Print the various setup data and the adjustment data (list) with
SIM22-6 and keep the data.
• In case of a memory trouble, if the data are not kept, all the

adjustments must be made again.

• If the data are kept, the setup values and the adjustment values

can be entered without adjustments, shortening the servicing
time.

1)

If the following options are installed, remove all of them from
the machine.
• Saddle stitch finisher
• Large capacity tray

2)

Remove the following consumable parts from the machine.
• Paper
• Toner cartridges
• Development cartridge

3)

Lock the following sections.
• Scanner (Optical section)
• Paper cassette lift plate

NOTE: Since the hard disk drive is built in the machine, use care

not to exert vibrations or shocks to the machine when in
transit.
