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

• Those with tears.

• Those smaller than size 148mm (W) x 140mm (L).

• Carbon-backed documents

TELEPHONE JACK

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

• Plugging the f ax machine into a jack which is not an 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 hav e 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 ak e the follo wing 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

230-240 V, 50 Hz, 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 mov ed from a cold to a warm place, this will prevent proper scanning of documents for transmission. Turn on the power and wait approximately 2 hours before using machine.

2. Assembly and connections

Plug the power cord into a 230-240 V, 50 Hz, earthed (3-prong) AC outlet.

Caution:

When disconnecting the fax, unplug the telephone line cord before unplugging the power lead.

• The mains outlet (socket-outlet) should be installed near the equip-

ment and be easily accessable.

• The machine does not have a power on/off s witch, so the power is

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

Note: If your area experiences a high incidence of lightning or power surges, we recommend that you install surge protectors f or the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores.

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.

3. 12. Entry data receive

This mode is used to receive the registered data from the other machine and to make your machine register the received data. Before receiving in this mode, it is necessary to set the other machine at the entry data send mode.

After receiving is completed, the machine prints the following lists:

1. Telephone list data

2. Soft switch list

3. Junk fax number list

3. 13. Cutter aging (Cutter model only)

This mode is used to consecutively cut the recording paper about 10 mm long and to display the number of cutting times.

(The number of cutting times is cumulatively counted unless you execute the memory clear.)

The operation is stopped in the following cases:

1. Hold down the stop key. (The cutter aging is stopped.)

2. No recording paper. (The cut operation is stopped.)

3. Recording paper jam. (The cut operation is stopped.)

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 s witch 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 ackno wledgment during G3 transmission

CHAPTER 3. MECHANISM BLOCKS

[1] General description

1. Document feed block and diagram

3-2. Automatic document feed

1) Use of the paper feed roller and separation rubber plate ensures error-free transport and separation of documents. The plate spring presses the document to the paper feed roller to assure smooth feeding of the document.

2) Document separation method: Separation rubber plate

Front sensor

Paper feed roller

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.

3. Hopper mechanism 3-1. General view

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

longitudinal size)

NOTE: Adjust the document guide after setting up the document.

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 stac k will be taken up b y the feed 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.

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.

• Copy 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.

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 power 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.

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.

2. Waveforms

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