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.

4.1.20. 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.

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.
