Basic operation
The printer routes all high-level processes through the formatter, which stores font information, processes
the print image, and communicates with the host computer.
The basic printer operation comprises the following systems:
●
The engine-control system, which includes the high-voltage and low-voltage power supplies (HVPS and
LVPS), fuser control circuits, 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 pickup, feed and delivery system, which uses a system of rollers and belts to transport the paper
through the printer
●
Optional accessories (paper feeder, paper decks, staple stacker multi-bin mailbox)
