Detailed explanation-1: -The primary corona wire applies a negative charge to the photosensitive drum as the surface of the drum rolls across the surface of the conditioning roller. This removes any electrical charges that might remain from the previous print image.
Detailed explanation-2: -A laser printer is a very high voltage, low amp, static charge generator. A bare corona wire carries a high voltage of 600 to 900 volts to apply an even charge over the surface of an organic photoconductive coating on a grounded steel bar.
Detailed explanation-3: -Before the paper rolls under the drum, it is given a negative charge by the transfer corona wire (charged roller). This charge is stronger than the negative charge of the electrostatic image, so the paper can pull the toner powder away.
