3.4 Print Principles
3.4.1 Charging
Using DC high voltage, the steel shaft of the charge roller will evenly charge the
surface of the OPC with a negative 600V charge.
3.4.2 Exposure
When the light conductor is scanned by the laser beam, the irradiated portion
meets the conductive layer of the photosensitive drum. This results in the removal
of the electric charge. Conversely, the non-irradiated surface retains its electric
charge, creating a potential difference image. This is often referred to as the
"electrostatic latent image."
