3. Document Types

• Normal paper
Documents handwritten in pencil (No. 2 lead or softer), fountain pen,

ball-point pen, or felt-tipped pen can be transmitted.
Documents of normal contrast duplicated by a copying machine can

also be transmitted.

• Diazo copy (blue print)
Diazo copy documents of a normal contrast may be transmitted.

• Carbon copy
A carbon copy may be transmitted if its contrast is normal.

4. Cautions on Transmitting Documents

• Documents written in yellow, greenish yellow, or light blue ink cannot
be transmitted.

• Ink, glue, and correcting fluid on documents must be dry before the
documents can be transmitted.

• All clips, staples and pins must be removed from documents be-fore
transmission.

• Patched (taped) documents should be copied first on a copier and
then the copies used for transmission.

• All documents should be fanned before insertion into the feeder to
prevent possible double feeds.

7. Use of Document Carrier Sheet

A document carrier sheet must be used for the following documents.

• Those with tears.

• Those smaller than size 5.8"(W) x 5.5"(L) (148 mm (W) x 140 mm

(L)).

• Carbon-backed documents

Make print straight

E.G.
Place the document
carrier in the document
feeder with the clear film
side down

Direction of insertion

NOTE: To transmit a carbon-backed document, insert a white sheet of

paper between the carbon back of the document and the docu­ment carrier.

• Those containing an easily separable writing substance (e.g., trac-

ing paper written on with a soft, heavy lead pencil).

NOTES:

• When using the document carrier, carefully read the in-

structions written on the back.

• If the document carrier is dirty, clean it with a soft, moist

cloth, and then dry it before using for transmission.

• Do not place more than one document in the carrier at a

time.

[4] Installation

1. Site selection

T ake the following points into consideration when selecting a site for this
model.

ENVIRONMENT

• The machine must be installed on a level surface.

• Keep the machine away from air conditioners, heaters, direct sun-

light, and dust.

• Provide easy access to the front, back, and sides of the machine. In

particular, keep the area in front of the machine clear, or the original
document may jam as it comes out after scanning.

• The temperature should be between 5° and 35°C.

• The humidity should be between 30% and 85% (without conden-

sation).

ELECTRICITY

120V, 60Hz, grounded (3-prong) AC outlet is required.

Caution!

• Connection to a power source other than that specified will cause

damage to the equipment and is not covered under the warranty.

• If your area experiences a high incidence of lightning or power surges,

we recommend that you install a surge protector for the power and
telephone lines. Surge protectors can be purchased at most telephone
specialty stores.

If the machine is moved from a cold to a warm place...

If the machine is moved from a cold to a warm place, it is possible that
the reading glass may fog up, preventing proper scanning of documents
for transmission. T o remove the fog, turn on the power and wait approxi­mately 2 hours before using the machine.

TELEPHONE JACK

A standard RJ11C telephone jack must be located near the machine.
This is the telephone jack commonly used in most homes and offices.

• Plugging the fax machine into a jack which is not an RJ11C jack may

result in damage to the machine or your telephone system. If you do
not know what kind of jack you have, or needed to have one installed,
contact the telephone company.

2. Connections

1

Connect the handset as shown and place it on the handset rest.
♦The ends of the handset cord are identical, so they will go into

either jack.

Use the handset to make ordinary phone
calls, or to transmit and receive docu­ments manually.

2

Plug the power cord into a 120 V, 60 Hz, grounded (3-prong) AC
outlet.

• Caution: Do not plug the power cord into any other kind of outlet.
This will damage the machine and is not covered under the war­ranty.

• The machine does not have a power on/off switch, so the power
is turned on and off by simply plugging in or unplugging the power
cord.

3

Insert one end of the telephone line cord into the "TEL. LINE" jack.
Insert the other end into a standard (RJ11C) single-line telephone
wall jack.

Be sure to insert the telephone line cord into the "TEL. LINE" jack.
Do not Insert into the "TEL. SET" jack.

3. Original document support

1

Rotate the original document support so that it points straight out.

4. Loading the fax paper

• Your fax machine prints incoming faxes on a special kind of paper
called thermal paper.

• The fax’s print head creates text and images by applying heat to
the thermal paper.

The available soft switches are SW-A1 to SW-L2.
The content of soft switches is shown in page 2-5 to 2-16.
The contents are set to factory default settings.

3. 2. ROM & RAM check

ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the buzzer
as well as by printing the ROM & RAM check list.
Number of short sounds of buzzer 0 → No error

1 → ROM error
2 → RAM error (32Kbyte)

3. 3. Aging mode

If any document is first present, copying will be executed sheet by sheet.
If no document is present, the check pattern will be printed sheet by
sheet. This operation will be executed at a rate of one sheet per 5min­utes, and will be ended at a total of 10 sheets.

3. 4. Panel key test

The mode is used to check whether each key operates properly
or not. Press the key on the operation panel, and the key will be dis­played on the display. Therefore, press all keys. At this time, finally press
the STOP key.

When the STOP key is pressed, the keys which are not judged as
"pressed" will be printed on the result list.

• LED port of the contact image sensor (CIS) is kept on during the
term from when start of the panel test mode to end with the STOP
key.

3. 5. Check pattern mode

This mode is used to check the status of print head. Two sheets of check
pattern are printed. The following information of check pattern is printed.

thermal head. RANK 0 or RANK 1 is printed at the tail of check pattern
to identify.

3. 6. Signal send mode

The mode is used to send various signals to the circuit during FAX com­munication. Every push of START key sends a signal in the following
sequence. Moreover, the signal sound is also output to the speaker when
the line monitor of the soft switch is on.

[1] No signal (CML signal turned on)
[2] 9600bps

[9] END

3. 7. Memory clear mode

This mode is used to clear the backup memory and reset to the default
settings.

3. 8. Shading mode

The mode is used for the shooting compensation. For reading, set up
the special original paper.

The shooting compensation memorizes the reference data of white and
black for reading.

Moreover, the memorized data is not erased even if memory clear mode
is executed.

3. 9. All black mode

The mode is used to check the state of the printing head and inten­tionally overheat it. Whole dots are printed over the interval of 2 m. If it is
overheated or the printing sheet is jammed, press STOP key for the end.

3. 10. Auto feeder mode

In this mode, a document is inserted and discharged to check the auto
feed function.

• Soft switch function description

SW-A1 No. 1 Protect from echo

Used to protect from echo in reception.

SW-A1 No. 2 Forced 4800BPS reception

When line conditions warrant that receptions take place at 4800 BPS
repeatedly.

It may improve the success of receptions by setting at 4800BPS.
This improve the receiving document quality and reduces handshake

time due to fallback during training.

SW-A1 No. 3 Footer print

When set to "1", the date of reception, the sender machine No., and the
page No. are automatically recorded at the end of reception.

SW-A1 No. 4 Length limitation of copy/send/receive

Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 0.6

meter for copy or transmit, and 1.5 meters for receive.
It is possible to set it to "No limit" to transmit a long document, such as a

computer print form, etc. (In this case, the receiver must also be set to
no limit.)

SW-A1 No. 5 CSI transmission

(CSI TRANSMISSION) is a switch to set whether the machine sends or
does not send the signal (CSI signal) informing its own telephone No. to
the remote fax. machine when information is received. When
"nonsending" is set, the telephone No. is not output on the remote trans­mitting machine if the remote transmitting machine has the function to
display or print the telephone No. of receiving machine, using this CSI
signal.

SW-A1 No. 6 DIS receive acknowledgment during G3 transmission

Used to make a choice of whether reception of DIS (NSF) is acknowl­edged after receiving two DISs (NSFs) or receiving one DIS (two NSFs).
It may be useful for overseas communication to avoid an echo sup­pression problem, if set to 1.

SW-A1 No. 7 Non-modulated carrier for V29 transmission modem

Though transmission of a non-modulated carrier is not required for trans­mission by the V29 modem according to the CCITT recommendation, it
may be permitted to a send non-modulated carrier before the image
signal to avoid and echo suppression problem. It may be useful for over­seas communication to avoid an echo suppression problem, if set to 1.

SW-A1 No. 8 EOL (End Of Line) detect timer

Used to make a choice of whether to use the 25-second or 13-second
timer for detection of EOL.
This is effective to override communication failures with some facsimile
models that have longer EOL detection.

SW-A2 No. 1 ~ No. 4 Modem speed

Used to set determine the initial modem speed. The default is 9600BPS.
It may be necessary to program it to a slower speed when frequent line
fallback is encountered, in order to save the time required for fallback
procedure.

SW-A2 No. 5 Sender’s information transmit

(SENDER’S INFORMATION TRANSMISSION) is a switch to set the
function to print the content of HEADER PRINT described in the passcode
list at the front end of receiver’s original when original is sent to the
remote machine.

If this switch is set to "NO", the HEADER PRINT is not output at the
receiving machine.

SW-A2 No. 6 H2 mode

Used to determine reception of H2 mode (15 sec transmission mode).
When set to OFF , H2 mode reception is inhibited even though the trans­mitting machine has H2 mode function.

SW-A2 No. 7 Communication error treatment in RTN sending mode
(Reception)

Used to determine communication error treatment when RTN is sent by
occurrence of a received image error in G3 reception. When it is set to
"1", communication error is judged as no error.

SW-A2 No. 8 CNG transmission

When set to "0" , this model allows CNG transmission by pressing the
Start key in the key pad dialing mode. When set to "1", CNG transmis­sion in the key pad dialing mode cannot be performed. In either case,
CNG transmission can be performed in the auto dial mode.

2. Document feed operation

1) The document placed in the hopper actuates the document sensor.
After one second, the pulse motor starts to drive the paper feed roller.
The document is automatically taken up into the machine, and stopped
at the document sensor.

2) When a specified number of pulses are received from the document
sensor after the document lead edge is sensed, scanning is started.

3) When a specified number of pulses are received from the document
sensor after the document rear edge is sensed, scanning is termi­nated and the document is fed through.

4) If the document sensor is active (i.e., another document is in the
hopper), when the preceding document scanning is completed and it
is fed out, the next document is taken up into the machine. If the
document sensor is not active (i.e., there is no document in the hop­per), when the document is fed out, the operation is terminated.

1) Make sure that the documents are of suitable size and thickness, and
free from creases, folds, curls, wet glue, wet ink, clips, staples and
pins.

2) Place documents face down in the hopper.
i) Adjust the document guides to the document size.
ii) Align the top edge of documents and gently place them into the

hopper. The first page under the stack will be taken up by the feed
roller to get ready for transmission.

NOTES: 1) Curled edge of documents, if any, must be straighten

out.

2) Do not load the documents of different sizes and/or
thicknesses together.

Use of a thermal head permits easier maintenance and low operating
costs.

1) Thermal head

The thermal head consists of 1728-dot heat elements arranged in a sin­gle row and has the resolution of 8 dots/mm. The maximum recording
speed is 10ms/line. The thermal head also incorporates a 1728-dot shift
register latch and output control driver circuit. Low power consumption
is achieved by dividing the head into nine segments.

2) Structure of the recording mechanism

Recording is accomplished by pressing the thermal head on the record­ing paper against the platen roller.

The main scan (horizontal) is electronically achieved, while the subscan
(vertical) is achieved by moving the recording paper by the recording
platen roller.

Usually, the cause for uneven print tone is caused by misalignment of
the thermal head or uneven contact with the roller.

It can be checked in the following manner.

1) Check if the thermal head power and signal cables are properly routed.

2) Check that the thermal head pivot moves smoothly up and down.

3) Check that the thermal head support bracket is secured without any
play.

4) Check to see that the recording platen roller has proper concentricity,
in the case of a print tone variation evenly repeated down the page.

5) Replace the thermal head with a new one and check to see if the
same trouble occurs.

3. Operational description

Operational descriptions are given below:

• Transmission operation

When a document is loaded in standby mode, the state of the docu­ment sensor is sensed via the 1 chip fax engine (XFC3). If the sensor
signal was on, the motor is started to bring the document into the
standby position. With depression of the START key in the off-hook
state, transmission takes place.
Then, the procedure is sent out from the modem and the motor is
rotated to move the document down to the scan line. In the scan
processor, the signal scanned by the CIS is sent to the internal im­age processor and the AD converter to convert the analog signal into
binary data. This binary data is transferred from the scan processor
to the image buffer within the RAM and encoded and stored in the
transmit buffer of the RAM. The data is then con-verted from parallel
to serial form by the modem where the serial data is modulated and
sent onto the line.

• Receive operation

There are two ways of starting reception, manual and automatic.
Depression of the START key in the off-hook mode in the case of
manual receive mode, or CI signal detection by the LIU in the auto­matic receive mode.

First, the XFC3 controls the procedure signals from the modem to be
ready to receive data. When the program goes into phase C, the
serial data from the modem is converted to parallel form in the mo­dem interface of the 1 chip fax engine (XFC3) which is stored in the
receive buffer of the RAM. The data in the receive buffer is decoded
software-wise to reproduce it as binary image data in the image buffer.
The data is DMA transferred to the recording processor within the
XFC3 which is then converted from parallel to serial form to be sent
to the thermal head. The data is printed line by line by the XFC3
which is assigned to control the motor rotation and strobe signal.

• Copy operation

T o make a copy on this facsimile, the COPY key is pressed when the
machine is in stand-by with a document on the document table and
the telephone set is in the on-hook state.

First, depression of the COPY key advances the document to the
scan line. Similar to the transmitting operation, the image signal from
the CIS is converted to a binary signal in the DMA mode via the 1
chip fax engine (XFC3) which is then sent to the image buffer of the
RAM. Next, the data is transferred to the recording processor in the
DMA mode to send the image data to the thermal head which is
printed line by line. The copying takes place as the operation is re­peated.

(4) Modem (R96DFXL-CID) block

INTRODUCTION

The Rockwell R96DFXL-CID MONOFAX modem is a synchronous 9600
bits per second (bps) half-duplex modem with error detection and DTMF
reception. It has low power consumption and requires only a single +5V
DC power supply. The modem is housed in a single VLSI device pack­age.
The modem can operate over the public switched telephone network
(PSTN) through line terminations provided by a data access arrange­ment (DAA).
The R96DFXL-CID is designed for use in Group 3 facsimile ma-chines.
The modem satisfies the requirements specified in CCITT recommen­dations V.29, V.27 ter, V.21 Channel 2 and T.4, and meets the binary
signaling requirements of T.30.
The modem can operate at 9600, 7200, 4800, 2400, or 300 bps, and
also includes the V.27 ter short training sequence option.
The modem can also perform HDLC framing according to T.30 at 9600,
7200, 4800, 2400, or 300 bps.
The modem features a programmable DTMF receiver and three pro­grammable tone detectors which operate concurrently with the V.21
channel 2 receiver.
The voice mode allows the host computer to efficiently transmit and
receive audio signals and messages.
The modem is available in either a 100-pin plastic quad flat pack (PQFP)
or a 64-pin quad in-line package (QUIP).
General purpose input/output (GPIO) pins are available for host as
signment in the 100-pin PQFP.
The modem’s small size, single voltage supply, and low power con­sumption allow the design of compact system enclosures for use in both
office and home environments.
MONOFAX is a registered trademark of Rockwell International.

Circuit

2-1. Noise filter circuit

The input noise filter section is composed of L and C, which reduces
normal mode noise from the AC line and common mode noise to the AC
line.

2-2. Rectifying/smoothing circuit

The AC input voltage is rectified by diode D1, 2, 3, 4 and smoothed by
capacitor C5 to supply DC voltage to the switching circuit section.

Power thermistor TH1 suppresses inrush current at power switch-on.

2-3. Switching circuit

This circuit employs the self excited ringing choke convertor (RCC) sys­tem. In this system, the DC voltage supplied from the rectifying/smooth­ing section is converted into high frequency pulses by ON/OFF repeti­tion of MOS FET Q1.

Energy is charged in the primary winding of T1 during ON period of Q1,
and discharged to the secondary winding during OFF period.

The output voltage is controlled by adjusting ON period of Q1 which
changes charge time of C9 through operation of photo-coupler PC1 from
+24V output.

Fig. 7

The overcurrent protection is performed by bringing Q1 to OFF state
through detection of voltage increase in the auxiliary winding of T1 by
ZD2 and R9.

The overvoltage protection is performed by operating the overcurrent
protection circuit through destruction of zener diode ZD4 and short­circuiting of load.

2-4. +5V circuit

Each DC voltage supplied by rectifying the output of transformer T1 with
diode D8 is stabilized by 3-terminal regulator IC1.

2-5. VTH circuit

VTH output is supplied through the relay RY1.
Relay RY1 is operated by VTH-ON signal.

[5] Circuit description of CIS unit

1. CIS

Cis is an image sensor which puts the original paper in close contact
with the full-size sensor for scanning, being a monochromatic type
with the pixel number of 1,728 dots and the main scanning density of
8 dots/mm.

It is composed of sensor, rod lens, LED light source, light-conductive
plate, control circuit and so on, and the reading line and focus are
previously adjusted as the unit.
Due to the full-size sensor, the focus distance is so short that the set
is changed from the light weight type to the compact type.
