1. Functions
The CORE/IP Board, Protocol Controller PCB, and Scanner Board provide the functions discussed on
the pages that follow.
a. CORE/IP Board
The CORE/IP Board processes and distributes image signals.
The board distributes image signals from the Image Processor PCB to the FAX Board or the Image
Server. The board also serves to forward image signals from these boards to the image processor PCB.
The board processes image signals by an ED method (error diffusion); i.e., binary processing, resolu-
tion conversion, and reproduction ratio processing.
You may install an CIST Board equipped with the ability to convert printer images to 1200 × 600 dpi
(main scanning × sub scanning).
