The main charging section consists of the main charger unit, drum, potential sensor and so on. The drum is electrically
charged uniformly by means of a grid to form a latent image on the surface.
The potential sensor (DPS) reads the drum surface potential and corrects surface potential.
The main charger unit has the main charger cleaning motor (CLM), main charger cleaning pad for automatic cleaning of
the charger wire.
The drum heater (DRH) inside the drum is turned on and off based on changes in ambient temperature and humidity to
stabilize the image quality.
