Purpose
:
Adjustment/Setup
Function (Purpose)
Used to set the density correction of copy
high density section (High density tone gap
supported).
Section
Operation/Procedure
1) Enter the set value with 10 keys. 
Press [OK]/[START] key. The set value is saved.
* When tone gap is generated in the high density area, set items
A and B to "0.
The density of high density part decreases. However, the tone
gap is better.
* To increase the density in the high density area further, set
items A and B to "1.
The tone gap may occur in high density part.
NOTE: Do not change the values of items 3, 4, 5, and 6.  . If these
values are changed, the density in the high density area is
changed.
