5) Press [OK] key.

NOTE:
Do not cancel the simulation until "PLEASE QUIT THIS
MODE" is displayed.

6) Check the color balance and density.

Check to insure that the printed color balance check patch
image is within the following specifications.

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.

c. 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.

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 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
