20 September 1999 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 analog 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 av ai l able
(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.)
5. SG3 unit: This provides one more analog line (PSTN) interface. This allows full
dual access (two communications can be made at the same time).
1.3.2 POWER DISTRIBUTION AND CONTROL
The FCU power is supplied from the base copier's BiCU (+2 4V, +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.

20 September 1999 VIDEO DATA PATH
Memory Transmission and Parallel Memory 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 (see
section 2-2-2), 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
the copier's SP modes.
Note that ISDN G3 tx is not possible on the PSTN-2 line.
JBIG Transmission
•
Memory transmission:
from the FACE (DCR) to the EXFUNC board for JBIG compression. Then either
the NCU or CiG4 (ISDN G3) transmits the data to the line. When an optional G3
unit (SG3) is installed and PSTN2 is selected as the line type, JBIG compression
is available, but only for the PSTN-2 line.
•
Immediate transmission:
from the page memory to the EXFUNC board for JBIG compression. Then either
the NCU or CiG4 (ISDN G3) transmits the data to the line. When an optional G3
unit (SG3) is installed and PSTN2 is selected as the line type, JBIG compression
is available, but only for the PSTN-2 line.
If the receiver has JBIG compression, the data goes
If the receiver has JBIG compression, the data goes
Adjustments
•
Line used for G3 transmissions (PSTN or ISDN): System switch 0A bit 6
•
Line used for G3 transmissions (PSTN 1/PSTN 2): System switch 16 bit 1
•
Use of the PSTN-2 line (rx only, or both tx and rx): Communication switch 16 bit
5
•
G3 line type: User parameter switch 6, bits 2 and 3
If this is at G3 auto selection, the machine can use either PSTN-1 or PSTN-2
If this is at PSTN-1, the machine will only use the PSTN-1 line.

Error Check
A895V502.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 (see section 2-2-2), the image is rotated in the page memory.
The data is transferred to the BiCU.
If the optional G3 unit is installed, the line that the message comes in on depends
on the telephone number dialled by the other party (the optional G3 unit has a
different telephone number from the main fax board).
Note that ISDN G3 rx is not possible on the PSTN-2 line.
JBIG Reception
When data compressed with JBIG comes in on PSTN-1 (the standard analog line),
the data is sent to the EXFUNC board for decompression. Then the data is stored
in the page memory, and transferre d to the BiCU.
When data compressed with JBIG comes in on PSTN-2 (optio nal extra analog
line), the data is sent to the QM-CODER on the SG3 board for decompression.

SCANNING FEATURES 20 September 1999
NOTE:
1) Even if Parallel Memory Transmission is enabled, the machine uses
normal memory transmission to send an A4 or 8.5 x 11" sideways
original.
2) If the machine carries out this function while printing, the machine stops
printing until scanning is completed.
3) The machine determine s if it will rotate the image after the paper size is
determined.
4) This feature is not performed during parallel memory transmission.
5) In Book mode, the machine determines image rotation for each page
scanned.
In ADF mode, the machine determines image rotation for the first page.
If it is rotated, all pages will be rotated. If the first page need not to be
rotated, all pages will not be rotated.
6) When this feature is enabled for A5 or HLT lengthwise, “APS small
original detection” must be changed. This allows the machine to detect
an A5/HLT size original. With the default setting, the machine does not
detect A5 or HLT lengthwise in book mode.

2.3.1 PAPER SIZE SELECTION
This section explains how the FCU selects the appropriate paper size for printing a
received fax image.
Width Priority and Length Priority
When “Width Priority” is selected , a paper size of the same width as the re ceived
fax image has a higher priority. The fax image may be printed on several pages.
When “Length Priority” is selected, a paper size that has enough length to print the
received fax image has higher priority. The fax image is printed on one sheet of
paper, but the printed fax may have wide margins on the left and right.

Image Rotation Before Printing
If the machine has the same size paper as the received fax image size, but in
sideways orientation, the fax unit rotates the image by 90 degrees clockwise, and
prints it sideways.
This feature is only possible when the received fax image is one of the following
sizes: A4 lengthwise, 8.5 x 11" lengthwise, B5 lengthwise
NOTE:
This function can not be disabled.

Sub-Scan Reduction and Page Separation
Sub-scan Reduction Disabled
When Sub-scan Reduction is disa bled, the received fax image is printed
unreduced.
If the image is longer than the paper length + 6 mm, the image is separated onto
two pages (see the top drawing below).
If the image is shorter than the paper length + 6 mm but longer than the paper
length - 4 mm, the part of the image after paper length - 4 mm will be lost (see the
bottom drawing below).
NOTE:
The page separation threshold is adjustable between 0 and 15 mm (the
default is paper length + 6 mm). Refer to Printer Switch 03, bits 4 to 7 for
more details.
The 2 mm gaps at the leading and trailing edges depend on the leading

Sub-scan Reduction Enabled
When Sub-scan Reduction is enab l ed, the received fax image is reduced in the
page memory to fit on the selected paper, if the received image length is between
[paper length - 4 mm] and [paper length + 20 mm]. See the drawing below.
A895D525.WMF
NOTE:
The upper limit (page length +20 mm) is adjustable between 0 and 155
mm. Refer to Printer Switch 04, bits 0 to 4 for more details.
If the FCU detects that the image must be separated into more than one page after
reduction, what happens to the data depends on the Reduction Rate Equalization
setting (Printer Switch 0E, bit 7).

reduction.
2. The last 10 mm of this data will be repeated at the top of the next page (this
length can be can be adjusted or repetition can be switched off).
3. The remaining data will be printed on page 2, with reduction, if it is within
[paper length + 20 mm].
4. If it is longer than this, page separation is done again. Data up to [page length 4 mm] will be printed on page 2, without reduction.
5. The process for page 3 and subsequent pages will repeat from step 2.

The data must be reduced to fit on pages of length (paper length - 4 mm), with an
equal reduction rate for each page.
The last 10 mm of the previous page will be repeate d at the top of the next page
(this length can be adjusted or repetition can be disabled).
2. The machine prints all the pages, at the same reduction rate.
If the customer does not want to receive a fax message on separate pages, page
separation can be disabled. However, once it has been disabled, the machine does
not print the received fax message until a paper size which can hold the received
fax image on one page is set in a cassette. Keep page separation enabled if the
customer expects to receive fax messages longer than the installed paper.

Page Reduction Sub-Scan Reduction
Reduced Image
A895D507.WMF
First, the received image is reduced by a fixed reduction rate in the main and subscan directions. The available reduction rates are as follows:
•
84% - A3 to B4 reduction
•
82% - B4 to A4 lengthwise reduction
Then, the reduced image is further reduced (if necessary) in the sub-scan direction
so that it can be printed on one page. However, if the FCU detects that the image
does not fit on one page after sub-scan reduction, the FCU cancels the page
reduction, but uses normal sub-scan reduction on the received fax image.
NOTE:
1) Sub-scan reduction is automatically enabled when Page Reduction is
enabled.
2) A3 to A4 reduction is not available.
