The following table shows the on/off status of Paper Size Switch in the SWITCH
ASSY SIZE according to the paper size.
ON:
Paper Size Switch is pressed by the actuator.
2.7.2 ROS Light Intensity Control
An image data converted to electric signals (expresses image data by ups and downs of
voltage) is sent to the laser diode in the ROS ASSY, and the laser diode converts the
electric signals to the light signals (controls on/off of the laser beam).
The laser diode monitors and controls the light intensity of the laser beam to create
stable electrostatic latent image without being affected by the fluctuations of the laser
beam intensity, optical system (such as lenses), and drum sensitivity.
The ROS of this printer has laser diodes for each yellow, magenta, cyan, and black, and
the light intensity for each color is automatically adjusted.
