3125 003
Auto TD Adj.
Specifies when to perform the Auto Toner Density 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 user 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.
3125 004 ACC
Enables or disables the process control self-check before printing the ACC pattern.
NOTE: If color balance changes during multi-copy runs after ACC is performed,
select 1 or 2. Setting 2 can precisely adjust the image density; however, it takes
about 6 minutes. Select 1 or 2 depending on the user's requirement.
3125 005 TD Adj. Cndtn
Specifies whether temperature and humidity are 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).
Specify "1" when both temperature and humidity are both high or low.
3125 006 TD Adj. Times
Limits the number of auto toner density adjustments. 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.
