Recorder The recorder, which is incorporated in the middle of the machine, consists of the recording head unit, coil spring, and platen. It prints according to received image signals.
Power Transmission Mechanism
The equipment has a single drive motor whose power transmission route can be switched by the planetary gear train and the solenoid. This switching allows the equipment to function in four operation modes (recording, scanning, copying, and cutter driving modes).
Structure of the gear train The gear train consists of two groups of gears: one group on the drive unit and the other on the scanner frame ASSY. Mounting the drive unit onto the scanner frame ASSY makes those two groups of gears engage with each other so that the rotation torque of the motor on the drive unit is transmitted to the separation roller, white pressure roller, and platen. Shown below are a group of gears, the motor and solenoid on the drive unit. The cutter gear (Q) is integrated in the cutter flange (R) whose boss is placed in the hole provided in the cutters upper blade.

Scanner frame ASSY Scanner Frame ASSY
Shown below is a gear train constructed by combining the drive unit and scanner frame ASSY. The motor rotation is transmitted via the planet gear 20B (C1) to the gear 16 (D) and via the gear 16/24 (K) to the separation roller gear (L).

Description of planetary gear system The planetary gear train consists of the sun gear 18/82, two planet gears 20, arm A, and arm B, as shown below.
Stopper of arm A Motor gear

Sun gear 18/82

Planet gear 20A

Planet gear 20B Arm A

Planetary Gear System
If the motor rotates, the sun gear 18/82 rotates so that the rotational torque 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 18/82. If the planet gear(s) becomes engaged with any other gear so that the arm cannot turn any more, the rotational torque of the sun gear 18/82 is transmitted to that planet gear. Accordingly, the planet gear starts rotation in the opposite direction of the sun gear 18/82.

Cutter driving mode (Solenoid: ON, Motor rotation: Reverse) The control electronics activates the solenoid to release the stopper of arm A from the clutch arm. When the motor rotates in the reverse direction, the sun gear 18/82 (B) rotates clockwise so that the planet gear 20A (C2) transmits the rotation to the cutter gear (Q) via gear P. Since the planet gear 20B (C1) is blocked by the section Y of the clutch arm, it is merely idle without engaging with any other gear.

The cutter gear (Q) is a two-stepped gear whose inside gear is a one-tooth sector gear. While the cutter gear (Q) rotates by one turn for one stroke of the upper blade of the cutter, the one-tooth sector gear slightly turns the platen gear (H) clockwise via the reverse gear (I) to feed the recording paper back into the equipment. This prevents the upper blade of the cutter from scratching the leading edge of the remaining paper.

Operating Procedure (1) Press the 1 and 0 keys in this order in the initial stage of the maintenance mode. The equipment displays the "WSW00" on the LCD and becomes ready to accept a firmware switch number. (2) Enter the desired number from the firmware switch numbers (01 through 37). The following appears on the LCD: WSWXX = (3) Use the and keys to move the cursor to the selector position to be modified. (4) Enter the desired number using the 0 and 1 keys. (5) Press the Set key. This operation saves the newly entered selector values onto the EEPROM and readies the equipment for accepting a firmware switch number. (6) Repeat steps (2) through (5) until the modification for the desired firmware switches is completed. (7) Press the Set or Stop key to return the equipment to the initial stage of the maintenance mode. NOTES: To cancel this operation and return the equipment to the initial stage of the maintenance mode during the above procedure, press the Stop key. If there is a pause of more than one minute after a single-digit number is entered for double-digit firmware switch numbers, the equipment will automatically return to the initial stage of the maintenance mode.

Selectors 1 and 2: Dial pulse generation mode
These selectors set the number of pulses to be generated in pulse dialing. N: Dialing "N" generates "N" pulses. (Dialing "0" generates 10 pulses.) N + 1: Dialing "N" generates "N + 1" pulses. 10 - N: Dialing "N" generates "10 - N" pulses.

0 : Yes

NOTE: Selectors 5 through 7 are not applicable in those countries where no busy tone detection is supported, e.g., China.
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.

V - 16

Selector 4:
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.
