Simplified Correction Control; Individual Registration Control - Konica Minolta A00F011 Service Manual

21. Image stabilization control
21.1.2

Simplified correction control

• If the simplified correction control is not effective in making a good correction, the com-
plete correction control is executed.

Theory of operation Ver.1.0 Nov. 2007
To check the low gain output value and offset voltage value of
the IDC sensor when the shutter is closed.
To check the low gain output value of the IDC sensor using
the intensity value set last for the clear transfer belt surface
on which no toner sticks.
To determine whether there is a leak based on the measure-
ment value taken last.
To correct the amount of toner based on the measurement
value taken last.
To correct based on the measurement value taken last.
To correct incorrect color registration that occurs due to varia-
tions in parts of the main body used for regulating different
drawing positions. The simplified control uses a simplified
registration pattern to make the correction.
