OVERALL MACHINE CONTROL 18 March 1998
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 t he analog li n e
between the fax unit and the optional external telephone.
Fax Options
1. ISDN unit: This allows the fax unit to communicate over an ISDN (Integrated
Services Digital Network) line.
2. EXSAF board: This expands the SAF memory capacity to hold up to 6MB of
received data or data for transmission. Al so, some additional features become
available. In addition, this expands t he syst em's SRAM capacity to hold
programmed telephone numbers, communication records, etc.
3. PMU board: This expands the page memory capacity to 4MB to enable 400 dpi
communications. Also, JBIG compression becomes available.
4. Hard Disk: This expands the SAF memory capacity to 130MB. The EXSAF is
required to install this option.
1.3.2 POWER DISTRIBUTION AND CONTROL
The FCU power is supplied from the base copier's BiCU (+24V, +12V, -12V, and
+5VE) and PSU (+5V). Refer to the base copier's service manual for det ails.
1.3.3 MEMORY BACK-UP
The system parameters and programmed items in the SRAM on the FCU and the
EXSAF board are backed up by batteries (long-term back up), in cas e the base
copier's main switch is turned off.
The SAF memory (DRAM) on the FCU and the EXSAF board are backed up by
rechargeable batteries for 1 hour.

VIDEO DATA PATH 18 March 1998
Memory Transmission and Parallel Memory Transmission
The base copier's scanner scans the original at the selected resol uti on in inch
format. The BiCU processes the data and transfers it to the FCU.
NOTE:
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.
Then, the FCU converts the data to mm format, and compresses the data in
MMR+raw format to store it in the SAF memory. If image rotation is possible, the
image is rotated in page memory before compression.
At the time of transmission, the FCU decompress es the stored data, then recompresses and/or reduces the data if necessary f or transmission. Either the NCU
or CiG4 (optional) transmits the data to the line.
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:
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.
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.
JBIG Transmission
•
Memory transmission:
With memory transmi ssion, if the receiver has JBIG
compression, the data goes from the SCP (DCR) to the PMU for JBIG
compression. Then either the NCU or CiG4 (ISDN unit) t ransmits the data to the
line.
•
Immediate transmission:
With immediate transmission, if the receiver has JBIG
compression, the data goes from the page memory to the PMU for JBIG
compression. Then either the NCU or CiG4 (optional) transmits the data to the
line.

First, the FCU stores the data from either an analog line or an ISDN line to the SAF
memory. (The data goes in parallel to the SCP, and is checked for error
lines/frames.)
The FCU then decompresses the data and transfers it to page memory. If image
rotation is possible, t he image is rot ated in the page memory. The data i s
transferred to the BiCU.
JBIG Reception
When the machine receives data compressed with JBIG, the data is sent to PMU
for decompression. Then the data is stored in the page memory, and transf erred to
the BiCU.

This function avoids the unintentional reduction of an A4 or 8.5 x 11” sideways
original. When the machine detects a sideways A4 or 8.5 x 11" original in the ADF
or on the exposure glass, the fax unit rotates the scanned image clockwise by 90
degrees before transmission, as shown above.
A5 or HLT lengthwise
This function avoids a blank space in the main scan direction. When the machine
detects an A5 or HLT original placed lengthwise in the ADF or on the exposure
glass, the fax unit rotates the scanned image clock wise by 90 degrees before
transmission, as shown above.

18 March 1998 SCANNING FEATURES
NOTE:
1) Even if Parallel Memory Transmissi on is enabled, t he machine uses
normal memory transmission t o send an A4 or 8.5 x 11" sideways

2) If the machine carries out this function while printing, the machine st ops
printing until scanning is compl eted.
3) The machine determines if it will rotate the image after the paper size is
determined.
4) This feature is not performed during parallel memory t ransm issi on.
5) In Book mode, the machine determ ines im age rotati on for each page
scanned.
In ADF mode, the machine determines image rotation for the first page.
If it is rotated, the machine will check each page. If the first page need
not be rotated, the machine will not check the rest of the pages.
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 PRINTING FEATURES
2.3.1 PAPER SIZE SELECTION
This section explains how the FCU selects the appropriate paper size for printing a
received fax image. Refer to the ’Paper Size Sel ect i o n Priorit i es’ tables at the end
of this section for how the appropriate paper size is actually selected.
WIDTH PRIORITY AND LENGTH PRIORITY
When ’Width Priority’ is select ed, a paper si ze of the same width as the received
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 f ax unit rotat es 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, B 5 lengt hwise

SUB-SCAN REDUCTION AND PAGE SEPARATION
Sub-scan Reduction Disabled
When Sub-scan Reduction is disabled, 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
and trailing edge margin settings.
The 10 mm image duplication can be adjusted or disabled.

PRINTING FEATURES 18 March 1998
Sub-scan Reduction Enabled
When Sub-scan Reduction is enabled, the recei ved f ax 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.
A693D526.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 Equali zati on
setting (Printer Switch 0E, bit 7).
- Reduction Rate Equalization Off (Example Diagram: Two-page Printout) -
A693D527.WMF
1. The data up to [page length - 4 mm] will be printed on page 1, without
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.

18 March 1998 PRINTING FEATURES
- Reduction Rate Equalization On (Example Diagram: Two-page Printout) -
A693D528.WMF
1. The machine determines how many pages will be needed to print the message,
taking the following into account:
The final page (n) is such that the received image length is within (paper length
x n) + 20 mm
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 repeated at the top of the next
page (this length can be adjusted or repetition can be disabled).
Detailed
Descriptions
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 recei ved
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.
