OVERALL MACHINE CONTROL 28 August, 2000
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 NCU switches the analog line 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. Also, some additional features become
available. In addition, this expands the system'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 80MB. The EXSAF is
required to install this option.
1.3.2 POWER DISTRIBUTION AND CONTROL
The FCU power is supplied from the base copier (+24V, +12V, -12V, and +5VE)
and PSU (+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
EXSAF 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 EXSAF board are backed up by
rechargeable batteries for 1 hour.

VIDEO DATA PATH 28 August, 2000
Memory Transmission and Parallel Memory Transmission
The mainframe's scanner scans the original at the selected resolution in inch
format. The mainframe processes the data and transfers it to the FCU.
NOTE: When scanning a fax original, the mainframe 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 com pression.
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.
Immediate Transmission
The mainframe's scanner scans the original at the resolution agreed with the
receiving terminal. T he mainframe video processes the data and transfers it to the
FCU.
NOTE: When scanning a fax original, the mainframe 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 (option al) transmits the data to the line.
JBIG Transmission
• Memory transmission: With memory transmission, 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) transmits 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.

Error Check
Base copier
B383V502.WMF
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, the image is rotated in the page memory. The data is
transferred to the mainframe.
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 transferred to
the mainframe.

2.2 SCANNING FEATURES
2.2.1 PARALLEL MEMORY TRANSMISSION
Using basic memory transmission, normally the machine starts dialing after the
document has been completely scanned. Using Parallel Memory Transmission, the
machine starts dialing at the same time the machine starts scanning. If the
document has multiple pages, the machine scans them into memory and sends
them while scanning continues.
NOTE: This function is only usable when sending an original from the ADF.

SCANNING FEATURES 28 August, 2000
• Send later transmission
• Broadcasting
• Transmission of an Auto Document only
• Transfer request transmission
• When Image Rotation before Tx is enabled, and an A4 s id eways or 8.5 x 11"
sideways original is detected
• If the other terminal is busy
• If the external telephone connected to the machine is in use
• When communication switch 0A, bit 0 is set to 1, and the m achine is using
memory transmission when redialing
• When remaining memory space is less than the threshold for parallel
memory transmission (default = 384 kB)
• When the original is located on the exposure glass
When using G4 transmission, parallel memory transmission is normally disab l ed,
because transmission using G4 is much faster than scanning. As a result, G4
transmission using parallel memory transmission takes about twice as long as
normal memory transmission (using an ITU-T #1 test chart).
If the document contains pages with complicated images or it is a photo document
using halftone, parallel memory transmission may be faster than normal memory
transmission. If the user commonly sends this type of fax message, enable parallel
memory transmission fo r G4 transmission by changing system switch 11, bit 7 to 1.

original is skewed, the machine corrects the sub-scan length to a standard paper
length.
The correction algorit hm is follows.
Before sub-scan length

Under 135mm 128mm (B6 short edge length)
136mm – 157mm 148mm (A5 short edge length)
158mm – 192mm 182mm (B6 long edge length)
193mm – 223mm 210mm (A4 short edge length)

Detailed
Descriptions
When this function is selected, the machine scans the original twice and transmits
the pages in the same sequence they were scanned.
With the default setting, the left page is sent first, then the right page is sent. If the
setting is changed, the order is reversed.

NOTE: 1) Memory transmission is used whenever this function is selected.
2) This function is only possible when sending a book original f rom the
exposure glass.
3) If this function is used for an A3 or 11 x 17" original, the pages may be
transmitted in a lengthwise direction, depending on the setting of "Image

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 clockwise by 90 degrees before
transmission, as shown above.
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 determines 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, the machine will check each page. If the first page need
not be rotated, the machine will not check the rest of the pages.

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 Selection Priorities’ tables at the end
of this section for how the appropriate paper size is actually selected.
WIDTH PRIORITY AND LENGTH PRIORITY
When ’W idth Priority’ is selected, 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.
Cross Reference
• Paper selection priority - Printer switch 0E, bit 0 (Default: Width)
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 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 adj ust ed or disabled.

PRINTING FEATURES 28 August, 2000
Sub-scan Reduction Enabled
When Sub-s can Reduction is enabled, 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.
B383D506.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 Rate Equalization Off (Example Diagram: Two-page Printout) -
B383D509.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.

28 August, 2000 PRINTING FEATURES
- Reduction Rate Equalization On (Example Diagram: Two-page Printout) -
B383D508.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 a t 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.

This function allows a received fax image to be printed on paper with less width
than the fax image.
Received Image

Reduced Image
Page Reduction Sub-Scan Reduction
Reduced Image
B383D507.WMF
First, the received im age 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 fa x image.
NOTE: 1) Sub-scan reduction is automatically enabled when Page Reduction is
enabled.
2) A3 to A4 reduction is not available.
Cross Reference
• Page reduction on/off - User parameter 10 (0A), bit 3 (Default: Disabled)

28 August, 2000 PRINTING FEATURES
Examples
1. When printing a B4 size fax image on 8.5" x 11" lengthwise paper
• Fax image size: 256 x 364 mm (10.7 x 14.3")
• Paper size: 216 x 279 mm (8.5 x 11")
• Reduction rate used: 82%
• Page separat ion threshol d: 20 mm
The received image is printed on one 8.5 x 11" sheet, because the image length
after page reduction (364 mm x 82% = 298.5 mm) is shorter than the paper length
(279 mm) plus 20 mm.
2. When printing a non-standard size (256 x 400 mm) fax image on 8.5 x 11"
lengthwise paper
• Fax image size: 256 x 400 mm (10.7 x 15.7")
• Paper size: 216 x 279 mm (8.5 x 11")
• Reduction rate used: 82%
• Page separat ion threshol d: 20 mm
The received fax im age is printed on two 8.5 x 11" sheets after page separation
and image rotation, because the image length after page reduction (400 mm x 82%
= 328 mm) is longer than the paper length (279 mm) plus 20 mm.

TWO IN ONE
This function allows two small pages to be printed on one sheet of paper. However,
this function only works when the machine does not have the following size of
paper in the cassette.
• The same size of paper as the received image
• The paper which has the same width and sufficient length
