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)

Engine control system
The interconnect board (ICB) provides connections from the formatter to the following components:
●
DC controller (DCC)
●
Scan control board (SCB)
●
Control panel, USB walk-up port, USB hardware integration pocket through a USB cable
The formatter receives +12 volts from the low-voltage power supply (LVPS).
The automatic document feeder/scanner receives 24 volts from the scanner power supply, which is powered
by an AC line from the LVPS.
The intermediate paper transport unit (IPTU) receives +24 volts and 3.3 volts from the DCC.
