Exposing
The main components in the exposure process are the system card, the printhead and the photoconductor unit.
The following illustration depicts a typical data path for a single color exposure.
Data is received from a computer into a port on the system card. The system card's RIP function converts this
data into raster information which is fed to the printhead along with other control data. The data is converted by
the printhead laser into light energy data that is directed to the light sensitive photoconductor unit.
