Exposure; Charging - Oki OKIOFFICE44 Service Manual

Charging

Charging is performed by applying DC voltage to the charge roller that is in contact with the surface of
the image drum.

Exposure

Light emitted from the LED head irradiates the negatively charged surface of the image drum. The surface
potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the
image signal.
