21.1 Configuration
• The following image stabilization controls are provided to ensure stabilized copy image.
Purpose Means Control
To stabilize image
density. Grid bias voltage ( V g)
Developing bias ( V b)
The V g/ V b control voltage is varied to bring V g/ V b
to an appropriate level according to the following
settings.
• ID ADJUST (Service mode)

V G ADJUST (Service mode)
• Print Density (Utility)
• SUPPLIES LIFE COU
N T. (Service mode)
To stabilize image
transfer. Transfer voltage ( V t)
Transfer electrical current (It)
The image transfer output is varied to bring the
image transfer electrical current to an appropriate
level according to the following conditions.
• Paper type
• Paper size
