When 2 is set, additional execution is performed regardless of environment.
When 3 is set, warm-up rotation is executed regardless of how long the machine is not used and
D-max/D-half control is additionally executed regardless of environment.
When uneven density at intervals of the Primary Charging Roller or Secondary Transfer Outer
Roller circumference or density variation occurs on approx. 10 images printed immediately after
the machine is not used for 8 hours or more
Enter the setting value, and then press OK key.
When D-max/D-half control is executed at warm-up rotation, it takes longer time for startup than

As the value is decreased, productivity and toner consumption are improved, but coarseness gets
worse.
