(2) Main charger unit
As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+)
corona charge dispersed by the main charger wire. Due to high-voltage scorotron charging, the charging wire
can get contaminated by oxidization after a long run. Therefore, the charger wire must be cleaned at a specific
interval. Cleaning the charging wire prevents print quality problems such as black streaks.
