II Composition/Operation
2.2.5 Laser light intensity control
• The laser light intensity control corrects the target level of fluctuations in fine line repro-
duction and reverse image (white on black) reproduction that occur due to variations in
photo conductor electrostatic characteristics, developing characteristics, and transfer
characteristics (part-to-part variations, environment, durability).
• It is controlled integrally with other control items by the image stabilization control.
• The laser light intensity control is performed when there is a request made for execution
of an image stabilization sequence.

2.2.6 Registration correction control
• In a tandem engine that has an image forming process for each color of toner, incorrect
color registration tends to occur due to variations in parts of the machine used for regu-
lating the drawing positions. The registration correction control automatically detects and
corrects this incorrect color registration.
• It is controlled integrally with other control items by the image stabilization control.
• The registration correction control is performed when there is a request made for execu-
tion of image stabilization sequence.
