Step 2: Expose
During the expose step, the LED exposes the surface of each photoconductor (B) and writes an invisible image
called a latent image or electrostatic image for each color.
The LED actually discharges the surface only where the beam hits the photoconductor. This creates a difference
in charge potential between the exposed area and the rest of the photoconductor surface.
Service tips
•
Never touch the surface of the photoconductor with your bare hand. The oil from your skin may cause
a charge differential on the surface, and toner will not stick properly. The result would be repeating
blotches of voids/light print on a page. Then the photoconductor will have to be replaced.
•
The surface of the photoconductor is coated with an organic substance that makes it sensitive to
light. Be sure and cover the photoconductor when you are working on the printer so you don’t “burn”
it. If exposed to light for too long, it will cause light/dark print quality problems and have to be
replaced.
