22. Image stabilization control
22.1 Overview
• The machine provides the following image stabilization control to ensure stabilized copy
image.
* An explanation is given of the control for each section.
Purpose Control Control means
To stabilize image density
To stabilize gradation
• IDC registration sensor adjust-
ment control
• Max. density adjustment control
• LD intensity adjustment control
• Registration control (color shift
correction)
• Gamma correction control
IDC registration sensor
Temperature/humidity sensor
PH temperature sensor
To stabilize toner density * TCR control (Y,M,C,K) TCR sensor
To stabilize image transfer
* Image transfer output control
