21. IMAGE STABILIZATION CONTROL

21.1 Configuration

• The following image stabilization controls are provided to ensure stabilized copy image.
Purpose
To stabilize image Grid bias voltage (Vg)
density. Developing bias (Vb)
To stabilize image Transfer voltage (Vt)
transfer. Transfer electrical current (It)
Grid bias voltage (Vg)
Means
The Vg/Vb control voltage is varied to bring Vg/Vb
to an appropriate level according to the following
settings.
• ID ADJUST (Service mode)
• VG ADJUST (Service mode)
• Print Density (Utility)
• SUPPLIES LIFE COUNT. (Service mode)
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
• B/W ratio of image
