Each drum is negatively charged and driven or rotated at a pre-determined speed through use of a stepper motor assembly.
Primary chargers function to uniformly charge the surfaces of the respective drums to a predetermined potential of negative polarity. Each cartridge contains the toner therein and, during operation causes the toner of each color to adhere to an electrostatic latent image formed on each drum to thereby develop the latent image as a toner image.
The primary charge rollers, also known as primary chargers function to charge the surfaces of the corresponding, respective drums to a predetermined, uniform electrical charge of negative polarity.
