17.1.2 Simplified correction control
• If the simplified correction control is not effective in making a good correction, the com-
plete correction control is executed.
Control name Purpose
1
AIDC Sensor offset value check
☞ 2-65
To check the low gain output value and offset voltage value of
the AIDC Sensor when the shutter is closed.
2
Check of AIDC Sensor output cor-
responding to clear Transfer Belt
surface
☞ 2-65
To check the low gain output value of the AIDC Sensor using
the intensity value set last for the clear Transfer Belt surface
on which no toner sticks.
3
Developing bias control (simplified
Vpp check)
☞ 2-33
To determine whether there is a leak based on the measure-
ment value taken last.
4
Developing bias duty control (con-
trol of the maximum amount of
toner sticking to the Transfer Belt)
☞ 2-34
To correct the amount of toner based on the measurement
value taken last.
5
Laser light intensity control (simpli-
fied correction control)
☞ 2-6
To correct based on the measurement value taken last.
6
Registration correction control
(simplified control)
☞ 2-6
To correct incorrect color registration that occurs due to varia-
tions in parts of the machine used for regulating different
drawing positions. The simplified control uses a simplified
registration pattern to make the correction.
