Basic operation

The product routes all high-level processes through the formatter, which stores font information, processes the print image, and communicates with the host computer.

The basic product operation comprises the following systems:

●The engine-control system, which includes the power supply and the DC controller printed circuit assembly (PCA)

●The laser/scanner system, which forms the latent image on the photosensitive drum

●The image-formation system, which transfers a toner image onto the paper

●The media feed system, which uses a system of rollers and belts to transport the paper through the product

●Option (optional paper feeder)
