    HL-2030/2040/2070N SERVICE MANUAL Print Process 2.5.1 Charging The drum is charged to approximately 897V by an ion charge which is generated by the primary charger. The charge is generated by ionization of the corona wire, which has a DC bias from the high-voltage power supply applied to it. The flow of the ion charge is controlled by the grid to ensure it is distributed evenly on the drum surface.

    CHAPTER 3 THEORY OF OPERATION 3. The laser beams reflected by the reflection mirror go straight toward the exposure drum below it, then expose the exposure drum. The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced, forming the electrostatic image to be printed.
