2. MECHANISMS

The facsimile equipment is classified into the following mechanisms:

 Scanning Mechanism - ADF mechanism

 Printing Mechanism - ACF and registration mechanism

 Power Transmission Switching Mechanism

 Sensors and Actuators

- Document scanning & feeding mechanism

- Printing and paper ejecting mechanism

III - 2

2.1 Scanning Mechanism

The scanning mechanism consists of the document stacker, automatic document feeder (ADF), separation roller, document LF roller, scanner, document ejection roller, and document sensors. (For details about the sensors, refer to Section 2.4.)

Automatic document feeder (ADF)

If you set documents with their faces down on the stacker and start the transmitting operation, the ADF (consisting of the separation roller and ADF parts) feeds those documents into the equipment, starting from the bottom sheet (first page) to the top (last page), page by page. Each document advances to the scanner with the document LF roller, and then it is fed out of the equipment with the document ejection roller.

Scanner

The scanner uses a contact image sensor (CIS) unit which consists of an LED array illuminating documents, a self-focus lens array collecting the reflected light, a CIS PCB carrying out photoelectric conversion to output picture element data, and a cover glass on which a document advances. When the document passes between the document pressure bar and the cover glass, it is scanned.

2.2 Printing Mechanism

The printing mechanism consists of the paper feeder, automatic cut sheet feeder (ACF), paper feed roller 32, platen, thermal recording head, paper ejection roller, and sensors. (For details about the sensors, refer to Section 2.4.)

Automatic cut sheet feeder (ACF) and registration mechanism

If the operator sets cut sheets into the paper feeder and receiving operation starts, the ACF (paper feed roller 32 and ACF parts) feeds paper into the equipment, a sheet at a time. After the leading edge of paper passes through the registration sensor actuator, the paper is further fed for the specified time length. Accordingly, the leading edge will reach the platen where the paper skew will be eliminated.

Printing and paper ejecting mechanism

The platen feeds the paper up to the printing position where the thermal recording head prints while the thermal ink ribbon advances. Then the paper is fed out of the equipment with the paper ejection roller.

2.3 Power Transmission Switching Mechanism

The facsimile equipment has a single drive motor whose power transmission route can be switched by the planetary gear system and by changing the motor rotation direction. This switching allows the equipment to function in five operation modes—scanning, paper feeding, recording, paper ejecting, and copying modes.

To switch to a particular mode, the motor rotates in the reverse direction. If the switching arm of the planet gear ASSY turns on the arm HP switch, the motor further rotates by the specified number of pulses to locate the planet gear ASSY in the particular mode position. Then the motor rotates in the forward direction to enter the particular mode.

2.4 Sensors and Actuators

This equipment has two photosensors and five mechanical switches as described below.

Ribbon sensor Photosensor Main PCB

Arm HP switch Leaf switch Drive unit

• Document front sensor which detects the 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.

• Cover sensor which detects whether the control panel ASSY is closed.

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

• Registration sensor which detects the leading and trailing edges of recording paper, which allows the controller to determine the registration timing and check paper jam.

• Ribbon sensor which detects whether the ink ribbon is loaded.

• Arm HP switch which detects whether the switching arm of the drive unit is placed in the home position.

*Not provided on models w/o handset.

The registration sensor and ribbon sensor is a photointerrupter consisting of a light-emitting diode and a light-sensitive transistor. Each of them has an actuator separately arranged (see the next page). When an actuator is not activated, its black end lies in the path of light issued from the lightemitting diode and interrupts its light so that the emitted light does not enter the light-sensitive transistor. If paper or ribbon comes in so as to activate the actuator, the actuator's black end goes out of the light path and the emitted light enters the light-sensitive transistor. This way, the sensor detects the presence of paper or ink ribbon.

nn Safety Precautions

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

(1) Unplug the power cord from the power outlet 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; otherwise, 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) Tighten screws to the torque values listed on the next page. (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) Before reassembly, apply the specified lubricant to the specified points. (Refer to Section 2 in

this chapter.) (10) After repairs, check not only the repaired portion but also that the connectors and other

related portions function properly before operation checks.

If you press the Pause key during dialing, the facsimile equipment will insert WAIT as defined in the above table.

If the Pause key is pressed repeatedly, the equipment inserts the specified WAIT multiplied by the number of depressions. It applies also in hook-up dialing.

When these selectors are set to "1, 0, 1": Each time you press the Pause key in dialing, the equipment will wait for

the 2nd dial tone to be sent via the communications line regardless of pulse dialing or tone dialing.

When these selectors are set to "1, 1, 0": If you press the Pause key in pulse dialing, the equipment will first wait for

the 2nd dial tone to be sent via the communications line. After that, pressing the Pause key will cause the equipment to insert a WAIT of 3.5 seconds. In tone dialing, the equipment will insert a WAIT of 3.5 seconds.

When these selectors are set to "1, 1, 1": If you press the Pause key, the equipment will first wait for the 2nd dial

tone to be sent via the communications line regardless of pulse dialing or tone dialing. After that, pressing the Pause key will cause the equipment to insert a WAIT of 3.5 seconds.

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

3.5 seconds.)

 Selectors 4 through 6: Detection of international tone
