14 January, 2000 OVERALL MACHINE CONTROL
The basic fax unit consists of two PCBs: an FCU and an NCU.
The FCU controls all the fax communications and fax features, in cooperation with
the base copier's main board, the BiCU. The NCU switches the an alog line
between the fax unit and the external telephone.
Fax Options
1. EXFUNC board: JBIG compression becomes available. In addition, this
expands the system's SRAM capacity to hold programmed telephone numbers,
communication records, etc.
2. PC fax expander: Class 2 fax communication from a PC and local printing from
a PC fax application become available (PC fax application required). Also, local
scanning from the machine’s scanner using TWAI N API beco mes available
(CFM Twain driver required).
3. ISDN unit: This allows the fax unit to communicate over an ISDN (Integrated
Services Digital Network) line.
4. EXMEM board: This expands the SAF memory capacity. Also, this expands the
page memory capacity to enable 400 dpi communications.)
1.3.2 POWER DISTRIBUTION AND CONTROL
The FCU power is supplied from the base copier's BiCU (+24V, +12V, -12V, and
+5V). Refer to the base copier's service manual for details.
1.3.3 MEMORY BACK-UP
The system parameters and programmed items in the SRAM on the FCU and the
EXFUNC board are backed up by batteries (long-term backup), in case the base
copier's main switch is turned off.
The SAF memory (DRAM) on the FCU and the EXMEM board are backed up by
rechargeable batteries for 1 hour.

14 January, 2000 VIDEO DATA PATH
Memory Transmission and Parallel Me mory Transmission
The base copier's scanner scans the original at the selected resolution in inch
format. The BiCU processes the data and transfers it to the FCU.
NOTE:
Then, the FCU converts the data to mm format, and compresses the data in MMR
or raw format to store it in the SAF memory. If image rotation will be done, the
image is rotated in page memory before compression.
At the time of transmission, the FCU decompresses the stored data, then recompresses and/or reduces the data if necessary for transmission. Either the NCU
or CiG4 (optional) transmits the data to the line.
When scanning a fax original, the BiCU uses the MTF and thresholding
parameter settings programmed in the fax unit’s scanner bit switches, not
the copier's SP modes.
Immediate Transmission
The base copier's scanner scans the original at the resolution agreed with the
receiving terminal. The BiCU video processes the data and transfers it to the FCU.
NOTE:
Then the FCU stores the data in page memory, and compresses the data for
transmission. Either the NCU or CiG4 (optional) transmits the data to the line.
When scanning a fax original, the BiCU uses the MTF and thresholding
parameter settings programmed in the fax unit’s scanner bit switches, not

Error Check
A874V502.WMF
First, the FCU stores the incoming data from either an analog line or an ISDN line
to the SAF memory. (The data goes to the FACE at the same time, and is checked
for error lines/frames.)
The FCU then decompresses the data and transfers it to page memory. If image
rotation will be done, the image is rotated in the page memory. The data is
transferred to the BiCU.
JBIG Reception
When data compressed with JBIG comes in on PSTN, the data is sent to t he
EXFUNC board for decompression. Then the data is stored in the page memory,
and transferred to the BiCU.

memory, then makes a fax transmission.
NOTE:
1) If the memory overflows while storing the first page into SAF memory,
the machine does not start the transmission.
2) If the memory overflows while storing the second or subsequent page
into SAF memory, the machine transmits all the successfully stored
pages.
3) When fax numbers programmed in the machine’s quick or speed dials
are specified using the PC fax application, all the specified numbers
must have been programmed in the fax machine.

The machine receives print data into SAF memory as fax image data, then prints it
after all the data has been transferred from the host PC.
The destination number “0000” informed from the host PC identifies a print job.
NOTE:
1) If SAF memory runs out while receiving print data, the machine prints up
to the successfully received data.
2) The machine cannot receive print data while printing a message from
the SAF memory. The data will be received after printing.
3) If a fax destination is specified together with the print destination “0000”,
the destinations specified after “0000” will be delayed until the machine
prints all pages in the message.

To add additional SC codes, program them in the blank addresses.
Wild Cards
This function allows “A” or “a”, to be used as a wild card instead of numbers from 0
to 9. For example, “1AA” or “1aa” means all the SC codes from 100 to 199, and
“39A” or “39a” means all the SC codes from 390 to 399.
The fax unit cannot make an automatic service call when a Fax SC code condition
has occurred. Refer to the Troubleshooting section for Fax SC code details.
Manual Service Call
If the service station needs a report, the user can make a service call manually, by
changing bit 7 of User Parameter 14 (0E) to “1”.

To change these settings after programming, change the call interval. The machine
then automatically changes the remaining parameters by referring to the interval
and the current date and time.
2.1.3 PM CALL
Detailed
Descriptions
If PM alarm is enabled with the base copier’s SP mode and PM call is enabled with
system switch 01, the machine will make an automatic service call when the base
copier’s PM counter reaches the PM interval.

Original Transmitted Image
When this function is enabled, the scanner is able to reduce the image of the
original. This allows the person at the other end to f ile the printout without losing
any of the data to punch holes.
The machine adds a margin to the bottom and left borders of the image so that the
transmitted page is the same size as the original.

Reduction ratio - System switch 06 bits 0 to 7
Default setting is 93% (71 to 99%)
NOTE:
1) This function is only possible during memory transmission.
2) “Create margin transmission” and “Image rotation before transmission”
are not compatible. (Create margin transmission is given priority)
3) The sample image on reports is also reduced and contains the margin.
4) Both the main and sub scan directions use the same magnification ratio.

LINE TYPE CHANGE 14 January, 2000
2.4 LINE TYPE CHANGE
When the machine is initially used only with the PSTN, t he line type programmed
with phone numbers in Quick Dials and Speed Dials is stored as PSTN G3.
Later, if the line connection is changed so that G3 is to be used only with the ISDN,
the communication port for all stored Quick and Speed Dials must be changed to
ISDN G3.
This feature allows the communication mode and port to be changed for all stored
numbers at once.
Procedure:
1) Change the data in the following RAM addresses.
68E8E4 (H) - Current line type setting.
68E8E5(H) – New line type setting.
NOTE:
2) Turn the main switch off and on.
3) After this procedure, the data programmed automatically returns to FF(H).
The default setting for the above addresses are FF(H).
Then, the machine checks all phone num bers stored in Quick Dials, Speed
Dials, AI Redial, and Forwarding Stations. If the communication mode and
the port setting for a number is the same as specified for the “current setting”
in the above address, the machine changes these to the “new setting”.
Setting:
These settings can be used only when an optional G3 and/or G4 unit is installed in
the machine.
Bit 0 and 1: Communication mode
Bit 1 0 Setting
0 0 G3
0 1 G4
Other settings - Not used
Bit 2 to 4: Communication port
Bit 4 3 2 Setting
0 0 0 PSTN
0 1 1 ISDN
Other settings - Not used
Bit 5 to 7: Not used
Allowable settings are as follows:
76543210 Setting
00H00000000 G3 (PSTN)
0DH 0 0 0 0 1 1 0 1 G4 (ISDN)
Example:
If you wish to change the port setting from PSTN to ISDN,
1. Change the data in address 68E8E4(H) to 00(H) (0000 0000)
2. Change the data in address 68E8E5(H) to 0D(H) (00001101)
2-8
14 January, 2000 LINE TYPE CHANGE
NOTE:
1) Do not use this procedure if there are any files stored in the memory
awaiting transmission.
2) Quick/Speed Dial addresses containing an F-code (i.e., for
communications that will use SEP/SUB/PWD/SID) cannot be converted
to ISDN G4.
