[4] Installation

1. Site selection

Take 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 du st.

• 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. To remove the fog, turn on the power and wait approximately 2 hours before using the machine.

If you are replacing the imaging film, take the old film out of the printing compartment and remove the three (3) green gears and the green flange from the ends of the spools.

DO NOT DISCARD THE GREEN GEARS AND THE GREEN FLANGE!

1 – 4

Page 7

Take the new film out of its package, and insert two of the gears provided with the fax into the ends of the spool with film. Make sure that the two tabs on the gears fit properly into the slots in the ends of the spool.

• Do not yet remove the band which holds the spools together.

UX-600MU/MC FO-1660U/C

Insert the empty spool into the back of the compartment so that the gear and the flange fit into the slots on the sides of the compartment.

• Make sure that the gear engages with the gear below it.

2 tabs

Hold the empty spool so that the end with only one slot is on the left, and lower the spools into the front of the printing compartment. The gears in the ends of the spool with film should fit into the slots on each side of the printing compartment.

Cut the band which holds the spools together with scissors, and remove it. Insert the remaining gear into the right end of the empty spool and the flange into the left end of the empty spool. Make sure the tabs on the gear and the flange fit into the slots in the ends of the spool (the gear has two tabs and the flange has one tab).

1 tab

Wind the film slightly (rotate the gear on the right side of the empty spool) so that there is no slack in the film. Make sure that both edges of the film wind onto the spool evenly.

Close the print compartment cover, making sure it clicks into place.

• Caution! Close the cover slowly to make sure it doesn’t pinch

your fingers.

3. 1. Soft switch mode

Used to change the soft switch settings. The soft switch which is stored internally is set by using the keys. The available soft switches are SW-A1 to SW-M2. 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 5 minutes, and will be ended at a total of 10 sheets.

3. 4. Panel key test

The mode is used to check whether each key properly operates or not. Since the key is displayed on LCD when the key on the operation panel is pressed, press all the keys. Here, finally press STOP key. When STOP key is pressed, the keys not judged as "pressed" are output in the result list. (The result list is not output in the process-diagnosis mode.) Here, the LED port can be turned on for CCD adjustment during the time from the start of the panel check mode to the end with the stop key.

3. 5. Check pattern

The mode is used to check the state of the printing head. It is ended with the following pattern printed on one printing sheet.

Longitudinal stripe 2 Approx. 30 mm 2 black dots and 2 white dots are repeatedly progressed on

one line.

Full black Approx. 30 mm

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.

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 1

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.

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.

3-4. 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 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.

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)

3-5. Documents requiring use of document carrier

1) Documents smaller than B6 (128mm x 182mm).

2) Documents thinner than the thickness of 0.06mm.

3) Documents containing creases, folds, or curls, especially those whose surface is curled (maximum allowable curl is 5mm).

4) Documents containing tears.

5) Carbon-backed documents. (Insert a white sheet of paper between the carbon back and the document carrier to avoid transfer of carbon to the carrier.)

6) Documents containing an easily separable writing material (e.g., those written with a lead pencil).

7) Transparent documents.

8) Folded or glued documents. Document in document carrier should be inserted manually into

the feeder.

4. Document release

4-1. General

To correct a jammed document or to clean the document running surface, pull the operation panel lock lever under the front center of the operation panel. To open the upper document guide, the operation panel must be opened first.

(2) Composition

The optical system is composed of the document feed mechanism, the LED lamp, the reflecting mirrors, the focusing lens, the CCD sensor, and the read process circuit.

5-1. LED Lamp/Lens

The LED lamp is used to project light to the document. NOTE: Take care for the position of the red mark on the lens. (Top

of the light-projected side)

5-2. CCD

The CCD (charge coupled device) image sensor consists of a photodiode array which converts the intensity of light reflected from the document surface into series of analog voltages which are then stored in an analog shift register. The series of analog voltages are then converted into a digital equivalent by a black/white binary logic circuit.

2) The peak output must be about 0.2 ~ 0.6 under room temperature to avoid CCD saturation.

6-1. Driving

In the drive mechanism, the rotating force of the pulse motor for both transmission and reception is transmitted to the paper supply roller, the recording paper feed roller and imaging film drive gear through the pulse motor axle gear, reduction gear and planetary gear.

6-2. Recording

This equipment employs the thermal transcription system which used the thermal head imaging film.

1) Thermal head

The thermal head is composed of 2,016 heating elements in traverse line, and the resolution power is 8 dots/mm. The maximum speed is 10 ms/line.

2) Structure of recording mechanism

Recording is achieved by applying a suitable pressure to the thermal head through the imaging film of the recording paper feed roller and the recording paper. The main scanning is electronically done, and the sub-scanning is mechanically done (by sending the recording paper with the recording paper feed roller).

3) Recording paper transfer sequence

a) The recording paper stored in the RP hopper is fed with the PU

roller, and the recording paper is stopped when the P-IN sensor is turned on by sensing its lead edge.

b) Hereafter, the imaging film and recording paper are transferred

with the recording paper feed roller, and thermal transcription is done on the recording paper.

c) After thermal transcription, the imaging film is taken up by the

roller on the take-up side, and the recording paper is discharged by the PO roller.

As basic, the density unevenness mainly results from the longitudinal misalignment of the thermal head to the heater line. Otherwise, the head is in uneven contact with the recording paper feed roller, or the imaging film is wrinkled.

The following items are described as the simplified checking method.

Are the power and signal cables of the thermal head suitably treated?

Does the same symptom appear even if the thermal head pressure spring is replaced?

Is the feed roller of the recording paper concentric? (Density is uneven at intervals.)

Does the same symptom appear even if the thermal head is replaced?

Is the imaging film stained or wrinkled?

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 (XFCRMVP). 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 CCD 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 XFCR-MVP 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 (XFCR-MVP) 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 main control gate array 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 XFCR-MVP which is assigned to control the motor rotation and strobe signal.

• Copy operation

To 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 CCD is converted to a binary signal in the DMA mode via the 1 chip fax engine (XFCR-MVP) 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.

3) Power supply PWB

This PWB provides voltages of +5V, VREG and +24V to the another PWB.

4) Panel PWB

The panel PWB allows input of the operation keys.

5) CCD PWB

This PWB controls the pickup optical device.

6) LCD PWB

This PWB controls the LCD display.

(4) Modem (R144EFXL) block

INTRODUCTION

The Rockwell R144EFXL MONOFAX modem is a synchronous 14400 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 modem satisfies the requirements specified in CCITT recommendations V.33, V.17, V.29, V.27 ter, V.21 Channel 2 (FSK), T.4, and T.3, and meets the binary signaling requirements of T.30. The modem can operate at 9600, 7200, 4800, 2400, or 300 bps. The modem supports the V.17 signalling rates of 14400, 12000, 9600, and 7200 bps using trellis-coded modulation (TCM). In addition, the modem supports V.27 ter and V.17 short trains. The modem can also perform HDLC framing according to T.30 at 14400, 12000, 9600, 7200, 4800, 2400, or 300 bps. An FSK flag pattern (7E) detector facilitates FSK detection in the high speed receiver. The voice mode allows the host computer (DTE) to transmit and receive audio signals and messages. The modem includes a programmable DTMF receiver and three programmable tone detectors which operate concurrently with the V.21 channel 2 (FSK) receiver. The three programmable tone detectors also operate concurrently with the voice mode receiver. General purpose input/output (GPIO) and general purpose input (GPI) pins are available for host assignment 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. The modem is available in either a 100-pin plastic quad flat pack (PQFP) or a 64-pin quad in-line package (QUIP). The package are shown in Figure 1. The general modem interface is illustrated in Figure 2. Additional modem information is described in the R144EFXL MONOFAX Modem Designer’s Guide (Order No. 895).

CIRCUIT

The power unit intakes input of AC 120V, 50/60 Hz and supplies output of +24V, +7.4V and +5V as shown in the block diagram. (See Fig. 8.)

2-1. Filter, rectifying and smoothening circuit

In the filter section, the noise generated from the power unit is eliminated from being discharged to the external, and external noise is prevented from entering. Thunder or other excessive surge is prevented by the varistor Z1. In the rectifying and smoothening section, AC input is rectified by the diodes D10, 11, 12 and 13, and is smoothened by the capacitor C5. Thus, DC voltage is supplied to the switching section. Moreover, the thermistor NTC1 prevents surge current when the power is turned on.

2-2. Switching section

The circuit uses the ringing choke converter of a self-excited type. Since MOS. FETQ1 is repeatedly turned on and off in this system, the DC voltage supplied from the rectifying and smoothening section is converted into the high frequency pulses. While Q1 is on, energy is accumulated in the primary winding of the transformer T1, and while Q1 is off, energy is discharged to the secondary side. Thus, the power is supplied.

Moreover, the frequency is varied depending on the load of the output. As the load becomes the heavier, the frequency becomes the smaller to extend the ON period. The constant voltage is controlled by applying the feedback to the control circuit through the photo coupler PC1 from +24V output. The overcurrent-protective circuit detects that the ON period becomes the wider as the output load becomes the heavier. For the control, the OFF period is extended by the control circuit to squeeze the energy which is accumulated in the primary winding of the transformer T1. For protection against overvoltage, the rise of the output voltage of +24V on the secondary side is brought into the overcurrent state through the continuity of the power zener diode D104 between +24V output and GND. Thus, the overcurrent-protective circuit of the control circuit is activated for the protection.

2-3. +24V circuit

Output is supplied by rectifying and smoothening the output of the transformer T1 with the diode D101 and capacitor C101.

2-4. +5V circuit

+5 V output is generated by rectifying and smoothening the output of the transformer T1 with the diode D102 and capacitor C102 and stabilizing it with the 3-terminal regulator IC103.

2-2. Scan optical system adjustment

(1) Outline

The adjustment procedures of the scan optical system are described below:

(2) Adjustment procedures

Switch off the machine and disconnect the AC power cable from

the wall socket.

Fully open the upper cabinet, remove the fixing screws of the recording paper tray and remove the recording paper tray. In order to perform a focus adjustment, remove the optical system unit from the frame.

Disconnect the main PWB from the TEL/LIU PWB.

Connect your oscilloscope channel 1 to the VIN signal and channel 2 of your oscilloscope to φT signal (Refer Pin 4 of connector CNCCD on the main pwb). Connect the earth clips of either probe to AG ground as shown. Set the trigger to channel 2.

UX-600MU/MC FO-1660U/C

Lightly loosen the red screws of the CCD PWB and obtain the VID signal waveform in synchronization with φT signal waveform. Adjust the CCD PWB positioning to obtain the waveform as shown below.

Re-connect the main PWB to the TEL/LIU PWB and connect these circuit boards to the connectors on the chassis.

Re-assemble up to and including the recording paper tray to the main chassis and close upper cabinet.

Plug the AC power cable into the wall outlet and turn the fax machine on.

Insert a test chart in the document hopper and execute the CCD Adjust Mode diagnostic. Press the START key to enable local copy until approximately one fifth of the page has been copied, then press the STOP key to enable the CPU wait state.

Fully open the upper cabinet and remove the recording paper tray.

Install the scan adjustment jig to the optical system unit, so that the pattern surface is on the lower side.

Fit the pins of the scan adjustment jig to the holes of the optical system frame.
