MECHANISMS
The facsimile equipment is classified into the following mechanisms: Scanning Mechanism Printing Mechanism - ADF mechanism - Document scanning & feeding mechanism - ACF and registration mechanism - Printing and paper ejecting mechanism
Power Transmission Switching Mechanism Sensors and Actuators
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.

Sensors and Actuators This equipment has two photosensors and five mechanical switches as described below. Sensor name Document front sensor Document rear sensor Cover sensor Hook switch* Registration sensor Ribbon sensor Arm HP switch · · Type Microswitch (SEN1) Microswitch (SEN2) Microswitch (SW2) Microswitch (SW1) Photosensor Photosensor Leaf switch Located on Control panel PCB Control panel PCB Sensor PCB Sensor PCB Sensor PCB Main PCB Drive unit
*Not provided on models w/o handset.
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.
· · · · ·
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.

DISASSEMBLY/REASSEMBLY
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.

These selectors activate or deactivate the dial tone detection function which detects a dial tone when a line is connected to the PABX. Setting both 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. Other setting combinations deactivate the dial tone detection function so that the equipment starts dialing after the specified WAIT (3.5, 5.0, or 7.0 sec.) without detection of a dial tone when a line is connected.
Selector 8: "R" key function
This selector determines whether or not the 1st dial tone detection function (specified by selectors 1 through 3 of WSW05) is added to the R key. If this selector is set to "0," pressing the R key automatically activates the 1st dial tone detection function when the PABX and the automatic calling are selected by using the function switch. If you press the R key and a dial number in succession, the equipment will automatically carry out the 1st dial tone detection function following the original transfer function as shown below.

Selector 1: Earth function in transfer facility
This selector determines whether or not the earth function is added to the transfer setting menu to be accessed by the function switch.
Selectors 2 and 3: Dual tone detection frequency in ICM recording
If the equipment detects either of the frequencies set by these selectors in ICM recording, it will disconnect the line. For example, if these selectors are set to "0, 0," the equipment will disconnect the line upon detection of 350 Hz or 440 Hz.
Selectors 4: Tone detection sensitivity in ICM recording
Setting this selector to "1" increases the tone detection sensitivity in ICM recording.
Selectors 5 and 6: Earth time length for earth function
These selectors set the short-circuiting time length of the telephone line (La or Lb) to ground. This setting is effective only when the earth function is selected for the R key by using the function switch.
Selectors 7 and 8: Break time length for flash function
These selectors set the break time length. This setting is effective only when the flash function is selected for the R key by using the function switch. V - 16

Selectors 1 through 3: 1st dial tone detection
These selectors activate or deactivate the 1st dial tone detection function which detects the 1st dial tone issued from the PSTN when a line is connected to the PSTN. 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, only a remote ID code whose second digit is detected within 2 seconds after detection of the first digit will become effective so as to 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.
