9 EXPLANATION OF MECHANISM
9.1. Printing Section
9.1.1 Print Head
• Printing mechanism is composed of;
• Head press solenoid
• Head press plate which is linked to the solenoid and the head press cover
• Head press lever which transforms the slide movement of the head pres s plate to rotational move-
ment at the fulcrum of the carriage shaft .
• Head press arm which transmits rotating movement to the head holder
• Head holder assembly which the thermal head is attached .
• As shown in the figure (Fig. 1), the head press solenoid engages the thermal head . In this condition,
printing is performed by movement of the carriage (Thermal Head)
9.1.2 Correction
• Correction of a printed character is performed by the lower of the two cartridges (correction tape car-
tridge). That is, the correction tape is lifted to the position of thermal head. In the character which is
to be corrected will be covered with white ink twice. (Fig . 2)
• Correction mechanism is composed of; (Fig . 3)
• Correction motor with correction worm gear
• Correction shaft with correction worm wheel
• Lift cam
• The rotating movement is transformed to slide movement (up-down) by the worm gear and the Lift
cam.

9.2 Ribbon Feed Section
• Winding of ribbon is controlled by the mechanism inside the carriage as shown in Fig. 4. That is, when print-
ing, the ribbon is wound continuously and when not printing, the ribbon is wound intermittently .
Winding Mechanism
1) When Printing
When printing , the head holder assembly ® moves toward the platen because the head press solenoid
is energized. The ribbon select arm @ (which presses against the head holder assembly ® ) also moves
towards the platen because of the ribbon select arm spring © .This causes the ribbon idle gear ® to
engage in the ribbon pulley @ . Since the ribbon pulley @ is rotated by the timing belt during carriage
movement, rotating power is transmitted from @ -®- ® - >@(ribbon winding assembly) and ribbon is
wound continuously.
2) When Not Printing
When not printing , the head holder assembly ® is held away from the platen by the head holder spring
®. Because of this, the ribbon idle gear ® is not engaged in the ribbon pulley @ so continuous rotating
power is not transmitted by the timing belt to the ribbon winding assembly ® .At this time the ribbon is
wound intermittently by the follow ing means. The intermittent winding cam CDis rotated by the timing belt.
This cam drives the intermittent winding lever Q), which drives the ribbon winding gear assembly ® by
means of the intermittent winding nail ® .

9.4. Paper Feed Section
9.4 .1 Power Transmission Mechanism
Revolution of the platen feed motor is transmitted to the platen gear through the platen middle gear.
(Fig. 7)
9.4 .2 Friction Feed Mechanism (Fig. 8)
The friction feed mechanism consists of the paper release roller and the paper release roller holder
which apply pressure to the platen, the paper release spring which gives pressure to the roller and roller
holder , the paper release shaft , the paper release link which turns the shaft , and the paper release lever
which guides the paper release link.
Pulling on the paper release lever in the direction of the arrow (v)causes the paper release shaft to
rotate, forcing the paper release springs downward and allowing the rollers to move away from the pla-
ten.
9.4 .3 Paper Out Detector (Fig. 9)
During continuous printing, the paper out sensor detects the end of the paper and outputs an electric
signal. An interrupting type photo sensor, located in opposition to the platen , detects the absence of
paper and generates the "END OF PAPER" signal.

10 EXPLANATION OF ELECTRONIC OPERATION
10.1. Principle of Operation
In this chapter, the basic operation of the electronic circuitry of the KX-W50TH /W60 TH thermal transfer
typewriters are explained.
The KX-W50TH/W60TH have two sensors. One sensor is a photo sensor, which senses a paper out
c0ndition. The other sensor is a mechanical switch, which is the home sensor for the carriage assembly.
The typewriter has five drive circuits which drive: the carriage motor, the paper feed motor , thermal
head, the head press solenoid and the correction motor. There is a three position mechanical switch
which is used for ribbon selection.
The KX-W50TH/W60TH Keyboard functions are the: type mode selector, keyboard selector, type pitch
selector, line space selector, text switch, print on/off switch, text key LED , which indicates the status of
the text mode (KX-W60TH only), mathematical function switches (KX-W50TH only), the LCD display
and the display contrast knob.
The mode status indicators of both machines display the setting of the : typing mode, keyboard, type
pitch, line space, indent, bold print, enlarge print, auto underline print mode, auto return, justification
mode, auto centering, the right margin flush mode, weak battery, and the text record status (KX-W60TH
only).

10.2. Circuitry
10.2.1. Power Supply Block
(1) Power and filter section
The power from the AC adaptor or the batteries is supplied to the power switch.
The absorption capacitor (C116) together with the filter removes noise entering the circuit
from the power source. The capacitors are also used for eliminating noise leaving the type-
writer to the power line.
As a result , the typewriter 's digital circuitry operates stable, and will be unaffected by noise
entering the circuit from the outside and prevents noise from leaving the typewriter.
(2) Power Circuitry
In this circuit, the Primary DC power passes through a switching regulator circuit , thus pro-
viding the necessary voltages for the control circuitry and drive circuitry . The voltage for the
thermal head is varied with the density controller (VA). Variable range is from 0-1.5 volts.
The following voltages are supplied:
DC +9 V : Stepping motor, Head press solenoid and DC motor
DC +6 ~ 7.5V : Therma l head
DC +5 V : CMOS logic·and Interface
DC -2V : LCD Display
During correction operation the thermal head voltage rises to its maximum voltage, this will
happen regardless of the density control knob setting.
Since all the thermal heads for this unit do not have the same resistance, adjustment of
thermal head volage is required.
Set thermal head voltage by rotating Variable resistor VR101 on Main P.C.B. accord ing to
the specified voltage which corresponds with the resistance of the individual thermal head
(Refer to section 4. Adjustment of thermal head voltage).
-23-

10.2.2 Reset Circuit
The reset circuit is provided to initialize the CPU HD6303X (IC101 ). About 300m- sec after the + 5V is
supplied to IC101, the reset signal on pin @ of IC104 changes from L to H: . _
In the standing state 0102 is turned on because of D111 and R115 voltage d1v1der, and 0 103 Is not turn ed
on.
When power is supplied to the circuit, 0103 is turned on before 010 2.
When 0102 is turned on, 010 3's collector, changes slowly from L to H beca use capacito r C108 is not
charged. . _
After stabilization of the + 5V by the time constant R117, R118 and C108, the potential of pm ® of IC104
increases and when it is larger than threshold level of pin @, pin @) of IC104 chang es fro m L to H. The
output of this delay circuit is sent to IC101 and the r~set operation is performed. . _
When the voltage drops, and current is Low, 0103 1s turned on because 01 02 Is not turn ed on. Sme e
0103 is turned on, the charge accumulated on C108 is quickly released. Also the potential of pin @ is
smaller than threshold level and pin @ changes from H to L.

(4) Address Decoder and Memory Map
The CPU can access a 64K byte memory area. The merAory area is divided into one 32K byte, and two 16K
byte blocks by IC104 using two address signals (A14, A15).
Each of the three blocks are tied to the ROM, RAM and 1/0 areas.
The RAM area is divided into SK byte by IC104 using one address sig nal (A 13).
By IC104, 1/0 area is divided into 4K byte blocks.
The CPU can access the 1/0, when the two address signals (A14, A15) are both L leve ls.
At this time the ROM and the RAM are disabled.

10.2.4 Interface Circuit
The interface circuit handles the handshaking needed for communica tion with a I/F Adaptor (RP-K100). The
RP-K100 allows interfacing with a host compute r.
The handshake method is described in the following steps.
Process;
(1) The RP-K100 changes the ON LINE signal from H to L indicating that data transmission has started . This
ON LINE signal remains Low during the transmission of 1 byte.
(2) The RP-K100 first sends the LSB (DO) of a transmitted byte to the TXD line and changes the STB signa l
from H to L. This STB signal is sent to P51 of the CPU which is the interruption.
(3) In the interruption state, the CPU receives a TXD signal and changes the ACK signal from L to H. This
ACK signa l is sent to the RP-K100.
(4) After the RP-K100 has received the ACK signal (L level), the STB signal changes from L to H.
(5) When the STB signal (High) is sent from the RP-K100, the thermalwriter sends the ACK signal (High)
to the RP-K100.
(6) When the ACK signal is High, the RP-K100 starts to send the next bit of data .
(7) Once the RP-K100 sends 1 byte of data (8 bits) to the CPU, the ON LINE signal changes from L to H.

10.2.5 Thermal head Drive Circuit
The thermal head on the KX-W50TH/KX-W60TH is composed of 28 dot shaped resistors.
When the current flows through the resistor, the resistor functions as a heating element.
When printing, 24 of the 28 dots are used. When correcting, all 28 dots are used.
The thermal head drive circuit receives its signals from the Gate Array (IC104).
These signals (25 bits) are fed to the driver (IC108, IC109, IC110 and IC111) which is a M54537.
This driver contains 7 NPN Darlington transistors .
Since a character font is determined by the dot matrix, the signals are synchronized with the Carriage Motor
timing and they are sent to the thermal head, as a result, a character is printed.
The head press solenoid on the KX-W50TH/KX-W60TH is a latch type plunger solenoid . This solenoid, dur-
ing printing, places the thermal head on the paper, and at return, lifts the thermal head off the paper. This
solenoid is driven by a bi-directional driver (IC112) which is a M54544L . This solenoid drive circuit receives
its signals from HEUP-HEDW of IC104.
The signal from CORH of IC104 is H level only during correction .
In the sequential timing of the software, the head press solenoid first places the thermal head against the
paper, then the Carriage Motor moves along the shaft, next the printing signals are sent to the thermal head.
