7-1. Overview of the Image Stabilization System
◆ The following image stabilization controls are provided to ensure
stabilized copy image.
Item Quality Purpose Control
Initial
Setting
Image
density,
gradation
To make an initial
adjustment of the
toner-to-carrier
ratio (T/C) control
level and optimum
Exposure Lamp
voltage using the
F5 operation.
• After making the variation adjustment
and contamination correction for the
AIDC Sensor, the copier produces a
solid-black and halftone pattern and,
through AIDC Sensor control, sets
the initial values for the T/C control
level and optimum Exposure Lamp
voltage.
Regular
Correction
Image
density
To compensate for
any drop in image
density due to a
deteriorating PC
Drum.
Gradation
To compensate for
any drop in the
intensity of LA1
light due to a
contaminated
optical system.
Foggy
background
To keep a given
T/C of the
developer in the
Developer Mixing
Chamber.
• The copier provides toner
replenishing control through ATDC
Sensor control. (*1)
• After making the AIDC Sensor
contamination correction, the copier
produces a solid-black pattern and,
through AIDC Sensor control, corrects
the T/C control level.
• The copier corrects the grid voltage
whenever the PC Drum has turned for
a given period of time.
• After making the AIDC Sensor
contamination correction, the copier
produces a halftone pattern and,
through AIDC Sensor control, corrects
the optimum Exposure Lamp voltage.
• The copier corrects the optimum
Exposure Lamp voltage whenever the
PC Drum has turned for a given
period of time.
