Printer Components

1.

Front Panel - The front panel provides the user interface to the printer.

2.

Image Processor Board - The image processor board converts the data from the
print jobs into bitmap images. The data passes through the engine controller board,

to switch the laser diode on and off during the printing process. The image

processor board contains:

■

Memory - RAM

■

Flash DIMM

■

NVRAM - Front panel and network settings.

■

Configuration Chip - determines the printer configuration.

■

Optional Hard Drive
