2. MECHANISMS

2.1 Transmitting Mechanism (Feeding and Scanning Documents)

The transmitting mechanism consists of the document stacker, automatic document feeder (ADF), document feeding related rollers, scanner, and document sensors. (For details about the sensors, refer to Section 2.3.)

If the operator sets documents on the stacker and starts the sending operation, the ADF feeds those documents into the equipment, page by page. Each document advances with the separation roller to the scanner, and then it is fed out of the equipment with the LF roller.

For the drive power source, refer to Section 2.4.

LF roller ASSY

2.1.1 Automatic document feeder (ADF)

The ADF, which consists of the separation roller and separator, feeds documents set on the document stacker, starting from the bottom sheet to the top, page by page, due to the frictional difference among the separation roller, the documents, and the separator.

2.1.2 Scanner

The scanner uses a charge coupled device (CCD) image sensor. As shown below, the LED array illuminates a document and the reflected light of the scanned

image data is transmitted via the mirrors into the lens which reduces the scanned data so as to form the image on the CCD.

2.2 Receiving Mechanism (Feeding Recording Paper & Recording Data)

The receiving mechanism consists of the recording paper roll holder, anti-curl system (ACS), platen, thermal recording head, automatic cutter, and sensors. (For details about the sensors, refer to Section 2.3.)

The recording paper is routed through the ACS to the recording head which prints onto the heat-sensitive recording paper pressed by the platen according to received image signals. The printed paper is further fed through the cutter chute and cut by the automatic cutter page by page.

For the drive power source, refer to Section 2.4.

Lower blade

(Rear)

2.2.1 Anti-curl system (ACS)

The ACS eliminates curl peculiar to the rolled recording paper by curving the paper towards the opposite side of the curl with the ACS rod and the ACS plate.

2.2.2 Automatic cutter

The automatic paper cutter consists of an upper blade (rotary) and a lower blade (stationary). As the upper blade rotates around the left end as a support, the recording paper will be cut. Upon completion of cutting operation, the upper blade returns to the home position which is detected by the cutter sensor.

Page 17

2.3 Sensors

This equipment has two photosensors and four mechanical sensors as described below. Photosensors

• Document front sensor which detects a presence of documents.

• Document rear sensor which detects the leading and trailing edges of pages to tell the control circuitry when the leading edge of a new page has reached the starting position and when the scan for that page is over.

These two photosensors are located on the main PCB. They are of a reflection type consisting of a light-emitting diode and a light-receiving transistor. Each of them has an actuator separately arranged (see the next page). If an actuator is activated, its white end will come to the path of light issued from the light-emitting diode and reflect its light. The moment the reflected light enters the light-receiving transistor, the sensor signals the detection.

Mechanical sensors

• PE (paper empty) sensor which detects whether the recording paper is present.

• Cover sensor which detects whether the recording paper cover is closed.

• Cutter sensor which detects the home position of the upper rotary blade of the automatic cutter.

• Hook switch sensor which detects whether the handset is placed on the handset mount.

These four sensors are located on the NCU PCB. Each of them has an actuator separately arranged (see the next page). If an actuator is activated, its lower end pushes down the lever provided on the corresponding sensor so that the sensor signals the detection.

2.4 Power Transmission Shift by the Planetary Gear Train and Clutch Solenoid

The equipment has a single drive motor whose power transmission route can be switched by the planetary gear train and the clutch solenoid. Accordingly, the equipment mechanism can function in four operation modes (recording, scanning, copying, and cutter driving modes).

2.4.1 Description of planetary gear train

The planetary gear train consists of the sun gear 18/73, two planet gears 20, arm A, and arm B, as shown below.

Arm B

Sun gear 18/73

Arm A

Planet gear 20B

Sun gear 18/73

Motor gear

Arm A

Planet gear 20A

Planet gear 20B

Arm B

Stopper of arm A

If the motor rotates, the sun gear 18/73 rotates so that the rotational force is transmitted to the engagement between the sun gear and the planet gears 20. Since the arms and planet gears are so designed that the moment of the arms is less than that of the planet gears, the arms turn around the center shaft in the same direction as the sun gear 18/73.

If the planet gear(s) becomes engaged with any other gear so that the arm cannot turn furthermore, the rotational force of the sun gear 18/73 is transmitted to that planet gear. Accordingly, the planet gear starts rotation in the opposite direction of the sun gear 18/73.

III – 6

2.4.2 Power transmission for four operation modes

Depending upon the clutch solenoid ON/OFF state and the motor rotation direction, the planetary gear train switches the power transmission route for the four operation modes.

In the recording mode, the control system deactivates the clutch solenoid (see the above figure, Solenoid: OFF). Therefore, when the motor rotates in the forward direction, the clutch lever turns clockwise with the spring and its cutout X becomes engaged with the stopper of arm A. Once arm A is locked, the planet gear 20A (C2) will not be engaged with any other gear but simply idle.

The motor rotation turns the sun gear 18/73 (B) counterclockwise so that the planet gear 20B (C1) transmits the rotation to the platen gear (E) via the gear D.

[ 2 ] Scanning mode (Solenoid: OFF, Motor rotation: Reverse)

Just as in the recording mode, the control system deactivates the clutch solenoid in the scanning mode to lock arm A.

The motor rotates in the reverse direction and the sun gear 18/73 (B) rotates clockwise so that the planet gear 20A (C2) transmits the rotation to the separation roller gear (L) and LF roller gear (O) via the several gears.

The control system at first activates the clutch solenoid to release the stopper of arm A from coutout X of the clutch lever while rotating the motor in the forward direction. Accordingly, the sun gear 18/73 (B) rotates counterclockwise so that both the planet gears 20B (C1) and 20A (C2) transmit the rotation to the platen gear (E) and the roller gears (separation roller gear and LF roller gear), respectively.

Once the planet gear 20A becomes engaged with the gear P, the control system deactivates the clutch solenoid.

The control system activates the clutch solenoid to release the stopper of arm A from cutout X of the clutch lever. When the motor rotates in the reverse direction, the sun gear 18/73 (B) rotates clockwise so that the planet gear 20A (C2) transmits the rotation to the cutter gear (Q).

Since the planet gear 20B (C1) is blocked by section Y of the clutch lever, it remains idling without engaging with any other gear.

3.3 NCU PCB

The NCU PCB switches the communications line to telephone or built-in MODEM, under control of the main PCB. Also, it works as a power supply interface from the power supply unit to the main PCB and the recording head.

As shown in the circuit diagrams on the next page, the NCU PCB consists of the components listed below:

1 Surge absorber 7 Calling signal detector 2 Noise filter 8 Loop current detector 3 Line relay (CML relay) 9 Dial pulse generator 4 Line transformer : Telephone circuit 5 Circuit related to line transformer a Recording head interface 6 High-impedance transformer circuit

• The primary function of the NCU which is shared by facsimile and telephone units is to switch a line to the facsimile unit or to the telephone, which is carried out by the line relay.

• Since the direct connection of a facsimile equipment to the line is not allowed for protecting the line, it is essential to insert a line transformer between the line and the facsimile equipment to insulate them each other in direct current band.

The above two components, a line relay and a line transformer, are the minimum requirements for the NCU of the facsimile equipment.

• If an external telephone is attached to the facsimile equipment, the NCU should have a loop current detector to identify the hook state by detecting loop current.

• If the facsimile equipment has an automatic answering facility, the NCU should be equipped with a calling signal detector which detects a calling signal and tells it to the CPU in the FAX engine.

• The circuit related to a line transformer allows the line transformer to be invariant by selecting the constants of the parts in this circuit so as to conform to the communications regulations or codes of each country.

In addition to the above basic components of the NCU, the following components are also required depending upon additional functions of the facsimile equipment:

• The dial pulse generator generates dial pulses within the facsimile equipment.

• The surge absorber is a protection circuit which absorbs lightning surge.

• The noise filter eliminates noise including radiation noise to prevent them from flowing out onto the communications line.

• The high-impedance transformer circuit detects the remote activation, and F/T switching sent from the line in ON-HOOK state without any interference to the line.

• The telephone circuit includes two amplifiers; one for amplifying the output signals of the handset microphone and the other for amplifying the receive signals from the communications lines to sound the handset receiver.

3.4 Control Panel PCB

The control panel PCB and the main PCB communicate with each other by serially transmitting commands and data.

The control panel unit consists of a gate array, an LCD, and LEDs, which are controlled according to commands issued from the FAX engine on the main PCB.

The calendar clock is backed up by the backup circuit on the main PCB. The panel FPC is a flexible keyboard PCB which integrates the key matrix having rubber

keytops.

3.5 Power Supply

The power supply uses the switching regulation system to generate the required DC power (+5V and +26.6V) from the commercial AC power supply.

The 26.6V power source is fed to the NCU PCB where the +26.6VH source is generated. The 26.6VH power source, which drives the recording head, outputs 26.6 VDC only when

the 26.6V ON/OFF control signal sent from the main PCB turns High. The 26.6V power source mainly drives the motor for feeding documents and recording pa-

per. Signals other than +26.6VH are connected to the main PCB through the NCU PCB and

+26.6VH is fed to the recording head.

1. INDICATION AND PRINTOUT OF ERROR

To help the user or the service personnel promptly locate the cause of a problem (if any), the facsimile equipment incorporates the self-diagnostic functions which display error messages for equipment errors and communications errors.

For the communications errors, the equipment also prints out the transmission verification report and the communications list.

2. EQUIPMENT ERROR

If an equipment error occurs, the facsimile equipment emits an audible alarm (continuous beeping) for approximately 4 seconds and shows the error message on the LCD. For the error messages, see Section 2.1. As one of the error messages, “MACHINE ERROR xx” includes an error code which indicates the detailed error causes listed in Section 2.2. T o display an error code for other latest error message, make the equipment enter the maintenance mode and press 8 and 2 keys (for details, refer to Chapter V, Subsection 3.3.9).

1. DISASSEMBLY AND REASSEMBLY

■ Safety Precautions

To prevent the creation of secondary problems by mishandling, observe the following precautions during maintenance work.

(1) Always turn off the power before replacing parts or units. When having access to the

power supply, be sure to unplug the power cord from the power outlet. (2) Be careful not to lose screws, washers, or other parts removed for parts replacement. (3) When using soldering irons and other heat-generating tools, take care not to damage

the resin parts such as wires, PCBs, and covers. (4) Before handling the PCBs, touch a metal portion of the equipment to discharge static

electricity, or the electronic parts may be damaged due to the electricity charged in your

body. (5) When transporting PCBs, be sure to wrap them in conductive sheets such as aluminum

foil. (6) Be sure to reinsert self-tapping screws correctly, if removed. (7) Unless otherwise specified, tighten screws to the torque values listed below.

• Tapping screws M2.6 : 3.5 kgf•cm M3 x 8 : 5 kgf•cm M3 x 10 : 7 kgf•cm

• Sems screws M3 : 7 kgf•cm

(Screws with washer)

• Stepped screws : 7 kgf•cm

(8) When connecting or disconnecting cable connectors, hold the connector bodies not the

cables. If the connector has a lock, always slide the connector lock to unlock it.

(9) After repairs, check not only the repaired portion but also that the connectors and other

related portions function properly before operation checks.

2. TROUBLESHOOTING

2.1 Introduction

This chapter gives the service personnel some of the troubleshooting procedures to be followed if an error or malfunction occurs with the facsimile equipment. It is impossible to anticipate all of the possible troubles which may occur in future and determine the troubleshooting procedures, so this chapter covers some sample troubles. However, those samples will help service personnel pinpoint and repair other defective elements if he/she analyzes and examines them well.

Prior to proceeding to the troubleshooting, read CHAPTER IV, INDICATION AND INFORMATION PRINTOUT OF ERROR.

2.2 Precautions

Be sure to observe the following to prevent the secondary troubles from happening: (1) Always unplug the AC power cord from the outlet when removing the covers and PCBs,

adjusting the mechanisms, or conducting continuity testing with a circuit tester.

(2) When disconnecting the connectors, do not pull the lead wires but hold the connector

housings.

(3) ● Before handling the PCBs, touch a metal portion of the machine to discharge static

electricity charged in your body.

● When repairing the PCBs, handle them with extra care.

● When removing the electronic devices with a soldering iron, do not leave solder chips

or lead wires inside the machine.

After repairing the defective section, be sure to check again if the repaired section works correctly. Also record the troubleshooting procedure so that it would be of use for future trouble occurrence.

2.3 Checking prior to Troubleshooting

Prior to proceeding to the troubleshooting flowcharts, check that: (1) Each voltage level on AC input lines and DC lines is correct. (2) All cables and harnesses are firmly connected. (3) None of the fuses are blown.

Setting all of these selectors to "1" activates the dial tone detection function so that the equipment starts dialing upon detection of a dial tone when a line is connected. (However, in those countries which support no dial tone detection function, e.g. in the U.S.A., setting these selectors to "1" makes the equipment start dialing after a WAIT of 3.5 seconds.) For the detecting conditions of the 1st dial tone, refer to WSW07 and WSW08.

Other setting combinations deactivate the dial tone detection function so that the equipment starts dialing after the specified WAIT (3.5, 7.0, 10.5, 14.0, 17.5, 21.0, or 24.5 seconds) without detection of a dial tone when a line is connected to the PSTN.

● Selector 4: Max. pause time allowable for remote ID code detection

This selector sets the maximum pause time allowable for detecting the second digit of a remote ID code after detection of the first digit in remote reception.

If selector 4 is set to "0" (2 seconds), for instance, a remote ID code whose second digit is detected within 2 seconds after detection of the first digit only will become effective so that the equipment will activate the remote function.

● Selectors 5 and 6: Busy tone detection in automatic sending mode

These selectors determine whether or not the equipment automatically disconnects a line upon detection of a busy tone in automatic sending mode.

Setting selector 6 to "0" ignores a busy tone so that the equipment does not disconnect the line.

Setting selectors 5 and 6 to "0" and "1", respectively, makes the equipment detect a busy tone only after dialing and disconnect the line.

Setting both of selectors 5 and 6 to "1" makes the equipment detect a busy tone before and after dialing and then disconnect the line.

● Selector 7: Busy tone detection in automatic receiving mode

This selector determines whether or not the equipment automatically disconnects a line upon detection of a busy tone in automatic receiving mode

Pressing the PAUSE key inserts WAIT in pulse dialing, as defined in the above table.

If the PAUSE key is pressed repeatedly, the equipment beeps a refusal sound and refuses the entry.

In hook-up dialing, however, the equipment allows repeated pressing with an acceptance sound, but inserts WAIT only for the first pressing.

Each time the PAUSE key is pressed, the equipment detects a 2nd dial tone.

If no 2nd dial tone is inputted within the specified time, the equipment disconnects the line in automatic dialing, or it starts transmitting the dial signal if given after depression of the PAUSE key in hook-up dialing.

(In those countries where no dial tone detection function is supported, setting these selectors to "1, 1, 0" or "1, 1, 1" inserts a WAIT of 3.5 seconds.)
