TR2 high-voltage power supply

The high-voltage power supply (HVPS) applies biases to the following components:

●Primary charging roller: The primary charging bias is applied to the surface of the photosensitive drum to charge it uniformly negative as a preparation for the image formation.

●Developing roller: The developing bias is used to adhere toner to an electrostatic latent image formed on the photosensitive drum.
