2.2.5.2 Process control
To ensure a stable image quality, parameters relating to image generation need to be
corrected on a timely basis. Control of the entire print process including the correction
of parameters is called "process control."
 TC (Toner Content) control
Toner patches for TC control are created on the Belt surface to measure the density
by the SENSOR ASSY ADC. According to the measured result, the amount of
toner supply, the amount of laser radiation, and the applied high voltage are
controlled. The execution sequence of the TC control is given on the next page.
