Charge; Expose; Develop - Lexmark MS911 Service Manual

Charge

A uniform negative electrical charge is applied to the surface of the photoconductor roller. The photoconductive
properties of the surface material allow it to hold the charge as long as it is not exposed to light.

Expose

The printhead emits the light that hits the surface of the photoconductor. The light turns on or off coinciding with the
digital image that is printed. The light causes areas of the photoconductor surface to lose its charge resulting in a relative
opposite polarity.

Develop

The developer feeds the toner from the toner cartridge to the photoconductor. The difference in charge causes the
toner particles to attract to the areas of the photoconductor exposed to light.
