The new model FR6 (FAX3800L) has been released as a successor model to the FX6
(FAX2700L).

This technical bulletin contains information on differences between the FR6 and the FX6.
They are listed in order of sections that appear in the service manual.

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.

The A4 development unit was modified to improve the flow of the toner in the development
unit. See page 2.

This modification prevents the Kattsumari problem (vertical gray bands on print outs)

∗

caused by blocked toner in the middle of the development unit. The blocked toner bends
the toner metering blade. The toner enters the drum area through the gap made by the
bent blade. Once in the drum area, the toner collects on the drum and causes the gray
bands on the print out.
(The toner flow was improved by the modification in MB F/L Series – 91B. This does the
job even better.)

1) The toner entrance becomes smaller to prevent too much toner from dropping into the
development unit. [Fig.1]

2) Toner Hopper Film, mentioned in MB no. F/L Series – 91B, has been strengthened to

push more toner up to the CTM. [Fig 2]

Note:
Interchangeability is O/O.
You can distinguish the modified development unit by the lot no. printed on the label.

See page 3.

Modification schedule:

From the mid-February production run except for the FR4.
(FR4 has the new part from the first production.)

SYMPTOM

This RTB is to clarify the symptom for the following error code.
Error code 0-52: Polarity change detected during communication.

CAUSE

Polarity change is detected during communication and the machine disconnects the line in
the following conditions (error code 0-52).

1. When the machine is at the Rx side (receiving a message) and when G3 bit switch 0B
bit 1 (Protocol requirements: Spain) is set to 1 (Enabled).
The machine immediately disconnects the line when it detects polarity change after
receiving DIS/NSF.

2. When the machine is at the Tx side (transmitting a message) and when G3 bit switch
03 bit 7 is set to 1.
The machine immediately disconnects the line if it detects polarity change twice after
receiving DIS/NSF.

NOTE:

G3 Switch 03

No FUNCTION COMMENTS

RC RE ASIA

The following explanation must be added to the service manual.

(All F/L series: FX6, FX6Mk2, FX4, FX7, LX7, LSO, LSOMk2, LFO, FR6, FR4)

1:
