OVERALL MACHINE CONTROL
1.4. OVERALL MACHINE CONTROL
Centronics
Interface
The FCE (Facsimile Control Engine) contains the FCIP (Facsimile Control
and Image Processor), DRAM, SRAM, System ROM, and video processing
memory. It controls the entire system through the IJC (Ink Jet Controller) and
the FDU (Facsimile Driver Unit).
There are two cpus in the machine: the main cpu (FCIP) on the FCE and the
ink jet control cpu on the IJC.
The FCIP consists of the following component blocks:
RU8 CPU - Main CPU
DMAC - DMA Controller
DIP - Digital Image Processor
