1.4 OVERALL MACHINE CONTROL
The FCU (Facsimile Control Unit) contains most of the logical components for
overall system control.
There are two CPUs in the machine: the main CPU (FCIP2) and the energy saver
CPU. Both of these are on the FCU. In energy saver mode, the main CPU switches
off and the energy saver CPU takes over.
