In addition to the functions of the FCU of the base facsimile machine (FX7),
the MCU (Multiple Control Unit) has some ICs, a bi-directional parallel interface, and an optional serial interface board. Using these interfaces, the
machine can communicate with a PC or Macintosh and work as a multi-function machine as a PC printer, PC scanner, and PC fax.
LX7
There are two major additional ICs (D6002 and D9001LF) on the MCU. 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 forwarded to the FCIP. In accordance with the firmware, the FCIP processes the
commands and controls the proper components related to the job. It controls
the MCB, 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 control procedure is the same as for jobs from a PC.

OVERALL MACHINE INFORMATION October 30th, 1996
OVERALL MACHINE CONTROL
1. PC Printer
For printing from Windows, the application software calls the printer driver
which is installed on the PC and forwards the data. The driver sends the data
using the Windows GDI and sends it to the machine via the parallel interface.
The data consists of compressed print data and control commands, such as
input tray selection, smoothing, and toner saving. The commands are received by the D6002 IC on the MCU and are sent to the FCIP. The FCIP
processes them and sends them to the MCB which controls the printer components. The FCIP and the MCB communicate with each other so that the
FCIP detects the printer status. When a PC sends a command to check the
machine status (input using the Status Display window), the MCU responds
with the printer status.
For printing from a Macintosh, the driver produces the data using QuickDraw
and sends it to the machine via the serial RS422 interface. Other control procedures are the same as for printing from a PC.
2. PC Scanner
For scanning, the TWAIN driver sends commands to the machine. The commands are received by the D6002 IC and sent to the FCIP. Then the FCIP
starts scanning by controlling the scanner components, such as the Tx motor
driver.
3. PC Fax
When transmitting data from a PC, the PC fax software produces the AT commands and sends them to the specified COM port of the PC. The software
redirects them to the specified parallel port. Then the commands and data
are sent from the parallel port to the machine. The D6002 receives them, and
the commands are sent to the FCIP. The FCIP controls the modem in accordance with the AT command sent from the PC, and the data is sent through
the modem and the NCU.
When receiving data, the data is stored in the ECM buffer in the same way as
for the FX7’s memory reception mode. The data is then sent to the PC via the
D6002.

The video data is compressed by the printer driver and then sent to the
D6002 through the parallel interface. The DRAM works as an input / output
buffer and sends reconstructed data to the D9001LF where smoothing and
toner saving are done. The data is then sent to the MCB for printing.

The scanned data passes through the DIP block in the FCIP for analog/digital
processing. The data is compressed in the DCR block in the FCIP and
passes through the ECM memory. Then it is sent to the PC through the
D6002 without any processing. The data is reconstructed in the driver in the
PC (the image processing is done in the same way as for fax scanning).

The PC data is compressed by the application software being used. The data
passes to the ECM memory through the D6002 without any processing. Then
it is sent to the telephone line through the modem and the NCU.
PC Fax Reception
The data from the line passes to the modem through the NCU. The data
demodulated in the modem passes to the D6002 through the ECM memory.
The data is reconstructed by the application software being used.
