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