7. Control
7.1 Paper size control
This device doesn't have switches for detecting paper size, and only length of paper is detected by
Regi Sensor when feeding paper. If printing data and paper size don't match, error is sended to the
controller.
7.2 ROS laser intensity control
PWBA LD (Laser Diode) converts image data of electric signal input to pulsing of laser beam.
7.3 Process control
It is necessary to correct parameters related to forming image occasionally in order to obtain stable
image quality at all times. Overall control of printing processes including correction of parameters
is called "Process control".
T TC (Toner Content) control
Sensor ADC reads concentration of toner patch for controlling TC created on the belt surface,
and according to the result of reading, toner supply amount, laser intensity or high voltage to
be applied is controlled.
