(2) Main charger unit
As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) corona charge dis-
persed by the main charger wire. Due to high-voltage scorotron charging, the charging wire can get contaminated by oxi-
dization 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.
