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
6280 Printer.
The primary function of the I/P Board is to receive host data through one
of the following available ports (USB or Ethernet). The received host data
is buffered, stored, and sent to the print engine in a rasterized format.
1. Standard Memory (256 MB on-board RAM)
2. Optional Memory DIMM (should be swapped)
3. Hard Drive Connection
4. NVRAM
5. Ethernet Connection
6. USB Connection
When installing a new I/P Board in the printer, you must transfer the
following parts from the old I/P Board to the new I/P Board:
■
Memory DIMM (if installed)
