Adjustment. When performing the Auto Toner
Density Adjustment, the machine supplies or
consumes toner so that the development gamma
is within ± 0.15 of the gamma target.

Change if the customer complains of toner density
fluctuations. Before changing the setting away
from 0, check whether the forced TD adjustment
(3-126-2) is effective. If the problem is persistent,
then change to 1, 2, or 3. However, the machine
takes several minutes to do this adjustment.

can precisely adjust the image density; however, it
takes about 6 minutes. Select 1 or 2 depending on
the customer's requirement.
taken into account when deciding the timing of the
auto toner density adjustment (described in SP 3-
125-3).
Timing for the auto toner density adjustment is
determined by the setting of SP3-125-003. In
addition, if SP 3-125-5 is set to 1, the auto toner
density adjustment is done when the temperature
and humidity meet specified conditions (same
conditions as used for transfer current correction).

adjustments.
[ 1 to 3 / 3 / 1/step]
The auto toner density adjustment consists of
three steps: detecting the development gamma,
supplying or consuming toner, and detecting the
development gamma again. When these three
steps are all complete, it means a single auto
toner density adjustment is complete.
