This adjustment must be performed in the following cases:
* When there is necessity to change the copy density of the low
density and high density part at each copy density individually.
* When there is necessity to change the density gradient of the
copy by each the copy mode individually.
* When there is necessity to change all copy density by each the
copy mode individually.
* When there is request from the user.
1) Enter the SIM 46-1 mode.
1) Enter the SIM 46-1 mode.
2)
Select the copy mode to be adjusted with the scroll key.
3)
Enter the adjustment value with 10-key and press [OK] key.
When adjusting the copy density on the low density part, select
"LOW" mode and change the adjustment value. When adjust-
ing the copy density on the high density part, select "HIGH"
mode and change the adjustment value.
When the adjustment value is increased, the copy density is
increased. When the adjustment value is decreased, the copy
density is decreased.
When adjusting the copy density on the low density part, select
"LOW" mode and change the adjustment value. When adjust-
ing the copy density on the high density part, select "HIGH"
mode and change the adjustment value.
When the adjustment value is increased, the copy density is
increased. When the adjustment value is decreased, the copy
density is decreased.
4)
Make a copy and check the adjustment result.
Switch the adjustment simulation mode and the normal copy
mode alternately, and adjust and check the adjustment result.
Repeat switching the adjustment simulation mode and the nor-
mal copy mode and changing the adjustment value and check-
ing the copy until a satisfactory result is obtained.
