The quality of a printed image is affected by changes in environmental condition where the machine is installed or changes in the characteristics of the photosensitive
drum and toner.
The machine performs the following controls according to necessity to stabilize print operation.
- Environmental change corrective control
To correct values of primary charging biases and developing biases based on the result of detection performed by the environment sensor. This is comparable
to a conventional D-max control.
- D-half control
To correct the gradation data in the main controller PCB based on the result of detection performed by the color displacement/density sensor
- Color displacement corrective control
To correct the timing of sending a video signal based on the result of detection performed by the color displacement/density sensor.
- Auto gradation correction control
To make a stable gradation density feature of image, customers need to execute any of full correction, quick correction or copy image correction.
Timing of execution of each control

*: Executed when 120 sheets are printed after the initial implementation
Executed when 500 sheets are printed after the 2nd implementation
Executed when 1000 sheets are printed after the 3rd implementation
Executed when 1000 sheets are printed thereafter
