1.4. OVERALL MACHINE CONTROL
The FCIP2 on the FCU board controls the entire system.
The FCU has some ICs, a bi-directional parallel interface, and an optional se-
rial interface board. Using these interfaces, the machine can communicate
with a PC and work as a multi-function machine as a PC printer, PC scanner,
and PC fax.
In every case of printing, scanning, or faxing from Windows running on a PC,
the control commands sent from the PC are received by the D6002, and for-
warded to the FCIP2. In accordance with the firmware, the FCIP2 processes
the commands and controls the proper components related to the job. It con-
trols the D6002 and D9001LF when printing, the scanner components when
scanning, and the modem when faxing.
For jobs from a Macintosh, the commands are received by the Z85230 IC on
the optional interface board and forwarded to the D6002. After that, the con-
trol procedure is the same as for jobs from a PC. (RS422 option is available
only in the U.S.)
