tomer's request.

To customize the following items after completion of the destination
setup, change the set values.

NOTE: Before checking the copy density and gradation, be sure to

execute the following jobs.

* Execute the high density image correction (Process correction)

forcibly. (SIM 44-6)

* Execute the half-tone image correction forcibly. (SIM 44-26)
(Method)
Make a copy of the gray test chart (UKOG-0162FCZZ), and check
