1.4. OVERALL MACHINE CONTROL
TECHNICAL BULLETIN
The FCE contains the FCIP2, DRAM, SRAM, System ROM, MN195003MFL modem, and
video processing memory. It controls the entire system through the FDU.
The FCIP2 does not contain the modem block. The Panasonic MN195003MFL modem is
used for all the communications (V.34, V.17, V.29, V.27ter., and V.21).
The 2 MB DRAM contains the SAF memory, ECM buffer memory, work area, and page
memory. The SAF memory can be extended by 1, 2 or 4 Mbytes with an IC card option.
A 1 MB (8 Mbit) flash ROM is used for the system ROM.
The FR6 uses two CPUs in the same way as the FX6. These are the main CPU in the
FCIP2 and the power saver CPU which is used during the 2 W power saver mode.
The main differences in PCB components between the FR6 and the FX6 are listed below.
FX6 FR6
FCIP used FCIP2 used
(The FCIP2 is used in common with
the LFO.)
FCE Rockwell R144EFXL modem used. Panasonic MN195003MFL modem
used.
512 kB (4 Mbit) flash ROM used. 1 MB (8 Mbit) flash ROM used.
1 MB DRAM used. 2 MB DRAM used.
FDU FPD motor driver used. SLA7024M motor driver used.

1.5. VIDEO DATA PATH
1.5.1 Transmission
TECHNICAL BULLETIN
Immediate Transmission:
Scanned data from the CIS passes to the DIP block in the FCIP2. After analog/digital
video processing, the DCR block compresses the data for transmission. The compressed
data then passes either to the FIFO memory or to the ECM memory before it is sent
through the modem. The MN195003 modem is used for all the communications.
Memory Transmission:
The scanned data is stored in the SAF memory after compression in the DCR block.
At the time for transmission , the DCR block decompresses the data from the SAF
memory, then compresses it again after handshaking with the other terminal is done. The
compressed data then passes either to the FIFO memory or to the ECM memory, before it
is sent.
Parallel Memory Transmission:
This feature allows the machine to scan a document into the SAF memory and send the
same document simultaneously.
The machine stores the processed video data in the SAF memory and sends the data
through the modem at the same time.

1.5.2. Reception
TECHNICAL BULLETIN
Data from the line passes to the modem through the NCU and hybrid IC. After the modem
demodulates the data, the decompressed data passes to the DCR block, through either
the FIFO or the ECM memory, where the data is decompressed to raster image data. At
the same time, the compressed data passes to the SAF memory as a backup in case of
mechanical problems during printing (substitute reception).
The raster image data is then passed to the page memory for printing. After a page of
data has been stored in the page memory, the data is sent to the LDDR through the LIF
block.

4.1. SERVICE LEVEL FUNCTIONS
4.1.20. Software Download (Function 12)
This function copies software from an external medium to the Flash ROM on the
machine’s FCE. The procedures to download the software are the same as for the FX6
series.
However, if you are using the EPROM board, you must mount two 4-Mbit EPROMs
because this machine uses an 8-Mbit EPROM on the FCE.
NOTE:
The Flash/SRAM data copy board which is used in common with the ADAM and
LFO (P/N: A1939351) must be used for this procedure.

09(H) - A fusing thermistor error was detected
11(H) - Charge leak current was detected while the charge corona unit was activated
12(H) - Charge leak current was detected while the charge corona unit was not activated
21(H) - The laser synchronization signal was not detected during printing
31(H) - Polygonal mirror motor startup error
32(H) - Polygonal mirror motor error during printing
41(H) - Main motor startup error
42(H) - Main motor erro r during printing
When a service call was caused by a fusing unit failure (codes 01 - 09):
After fixing the problem, reset the data at this address to 00(H), then restart the
machine to clear the service call. (Refer to address 800371(H) for other hardware
failures.)
Either or both of these bits will change to 1 when an excessive jam alarm occurs.
Reset each bit to 0 when you have solved the problem. The machine will not be
able to detect excessive jams in future if you do not reset these bits.
