Image Processor Board
The Image Processor Board (I/P Board) is one of the major elements of the
Phaser 5500 printer. The primary function of the I/P Board is to receive host data
through one of the following available ports (Parallel, USB, or Ethernet). The
received host data is buffered and stored and sent to the print engine in a rasterized
format. The secondary function of the I/P Board is to provide print control, Front
Panel control, configuration setup, error reporting, and job recovery.
Before the I/P Board can receive and process data it must first pass the Power On Self
Test (POST). This test process verifies proper operation of the Image Processor and
prepares it for processing the host data by putting the Image Processor in a known
state.
The Image Processor Board connects to the Engine Logic Board directly. The Front
Panel is connected to the Image Processor Board and signals pass through the Engine
Logic Board via the Image Processor.
