● Control timing
Execution items for image stabilization control differ according to the environment and
condition of image formation parts.
Following shows the control items at each sequence and estimated downtime.

Control
At power-on At power-on ○
At recovery from

At recovery from sleep mode ○
At initial rotation At initial rotation of PASCAL control or D-half
control
○
At paper interval
At paper interval on a specified print basis
(80 sheets or more)

At paper interval on a specified print basis
(200 sheets or more)

At last rotation
At last rotation on a specified print basis
(30 sheets or more)

At last rotation on a specified print basis
(1000 sheets or more)
○
At last rotation after printing when the designated
temperature difference or humidity difference
from the previous execution has been exceeded
○
At last rotation when PASCAL control is executed ○
At last rotation of PASCAL control or D-half
control
○
At installation
or during parts
replacement
When replacing the Drum Unit ○ ○
During installation and when replacing the Drum
Unit
○
When UI menu
is executed
When calibration is executed
(When "auto gradation adjustment -> full
adjustment" is executed)
○
When "Auto color displacement correction" is
executed*
○
* When it is determined necessary based on the predicted value for temperature inside the
machine (according to the usage environment and continuous print state).
The control is executed based on the predicted value; therefore, there is no specific timing
for control timing.
T-2-27
● D-max Control
The optimal laser output is determined.
Control timing
1) When replacing the Drum Unit
2) At last rotation or paper interval on a specified print basis (200 sheets or more)
3) At last rotation after printing when the designated temperature difference or humidity
difference from the previous execution has been exceeded
4) At initial rotation of PASCAL control or D-half Control
Control description
1) Main Controller PCB forms patch pattern in the target color on the ITB.
2) The DC Controller measures patch density by the Registration Patch Sensor Unit
(Front) (UN31)/Registration Patch Sensor Unit (Rear) (UN32) to correct developing
bias, primary charging bias and laser output in each color to meet the target density.
