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 yello w, or light b lue 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 before 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.

• Those with tears.

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

(L)).

• Carbon-backed documents

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 jac k which is not an RJ11C jac k may

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

Make print straight across paper 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 f ollowing points into consideration when selecting a site f or 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

AC 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...

Condensation may from on the reading glass if machine is moved from a cold to a warm place, this will prevent proper scanning of documents for transmission. Turn on the pow er and w ait approximately 2 hours before using machine.

2. Assembly and connections

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

• Caution: Do not plug the power cord into an y 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 po wer is

turned on and off by simply plugging in or unplugging the power cord.

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.

Make sure the handset cord goes into the jack marked with a handset symbol on the side of the machine!

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

Attach the original document support as shown below.

2) Document separation method: Separation rubber plate

Separation rubber

Feed plate

Document

Paper feed roller

Fig. 1

2. Document feed operation

1) The original, which is set in the document hopper, feeds automatically when the front sensor is activated. This in turn activates the pulse motor which drives the document supply roller. The document stops when the lead edge is detected by the document sensor.

2) The lead edge of the original is fed a specified number of pulses after the lead edge of the document is detected for the reading process to begin.

3) The trailing edge of the original is fed a specific number of pulses after the trailing edge of the document deactivates the document sensor. The read process then stops and the original is discharged.

4) When the front sensor is in the OFF state (any document is not set up in the hopper guide), the drive will be stopped when the document is discharged.

Documents corresponding to a paper weight heavier than 69.2kg (80g/ m2 ) and lighter than 135kg (157g/m2 ) are acceptable for manual feed.

Documents heavier than 135kg in terms of the paper weight must be duplicated on a copier to make it operative in the facsimile.

3-4. Loading the documents

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 tak en up by the f eed roller to get ready for transmission.

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

out.

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

Fig. 2

The hopper section contains document guides that are used to adjust the hopper to the width of the original document. This ensures that the original feeds straight into the fax machine for scanning. Document width: 148 mm to 216 mm (A5 longitudinal size to Letter

5-2. Driving

Via the pulse motor gear shaft, the reduction gear, and the recording paper feed gear, rotation of the pulse motor is con ve yed to the recording paper feed roller to feed the recording paper.

5-3. Recording

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 po wer 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 by 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 (FC200). 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 converted 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 FC200 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 (FC200) 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 FC200 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 FC200 which is assigned to control the motor rotation and strobe signal.

• Cop y operation

T o mak e a cop y on this facsimile , the COPY ke y 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 (FC200) which is then sent to the image buff er 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.

5) LCD PWB

This PWB controls the LCD display.

(4) Modem (FM209) block

INTRODUCTION

The CONEXANT FM209 MONOFAX modem is a synchronous 9600 bits per second (bps) half-duplex modem with error detection and DTMF reception. It has low pow er consumption and requires a single +5V and +3.3V 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 FM209 is designed for use in Group 3 facsimile machines. 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 128-pin plastic quad flat pac k (TQFP). General purpose input/output (GPIO) pins are available for host as signment in the 128-pin TQFP. 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 CONEXANT.

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 inr ush 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.

[5] Circuit description of CIS unit

1. CIS (Contact Image Sensor)

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 f ocus distance is so short that the set is changed from the light weight type to the compact type.

The overcurrent protection is performed by bringing Q1 to OFF state through detection of voltage increase in the auxiliary winding of T1 by R5 and R7.

2-4. +5V circuit

Each DC voltage supplied by rectifying the output of transf ormer T1 with diode D9 is stabilized.

2. Waveforms

The following clock is supplied from FC200 of the control board, and VO is output.
