Theory of Operation
Image Processor Board
The Image Processor (I/P) Board is connected to the MCU Board, which
controls the printer, including Diagnostic, Interface, and Image
Processing. The I/P Board is one of the major elements of the Phaser
6180 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, stored, and sent to the print engine in a rasterized
format.
1. Standard Memory (128 MB on-board RAM)
2. Optional Memory DIMM (should be swapped)
3. Multi-Protocol Network Card Connection
4. NVRAM
5. Ethernet Connection
6. PC Interface Connection (Parallel)
7. USB Connection
When installing a new I/P Board in the printer, you must transfer the
following parts from the old board to the new board:
■
Memory DIMM (if installed)
■ NVRAM
■
Multi-Protocol Network Card (if installed)
