3.2 circuit description
3.2.1 power circuit
POWER VOLTAGE (+5V,-30V,VEE,,VF1,VF2) REGULATOR CIRCUIT
After passing through the switching regulator. There is a +24V DC power via JP1.
This power supply circuit employs fly back converter type switching regulator system.
At the initial condition, as the level of point “I” is 0V, PQ4 keeps OFF condition.
When +24V begins to rise up after power ON, the level of point “H” rises up and PQ1 turns ON.
And then the power is applied to primary side of pulse transformer (PT1).
When the power is applied to primary side of the PT1 , the level of point
“I” (secondary side of the PT1 ) rises up, and if it is exceed the zenner voltage
of PD11(+5V), PQ4 turns on and the level of point “H” becomes 0V.
Therefore PQ1 is in OFF condition and supplement to primary input of PT1
is cut off, with that the level of point “I” becomes initial condition again and PQ1 turns ON.
Thus , switching the supplement of power to primary side of PT1,
secondary output(+5V,-30V,VF1,Vf2) is stable.
The +24V DC pass through u1(LM2575S-5.0 voltage regulator)become Vcc-c steady.

3.2.2 KEY BOARD CIRCUIT
Input and output signal for key board scanning are passing through J1,J2
The output signals from output port (P110-P113) of U17 are encoded signals.
By passing through U25,U26(74HC138), they are decoded to key scan signals. And they are
applied to key matrix via J1.
When a certain key is depressed, one of decoded signal is applied to buffer(U20:74HC245) via J2.
Thus U17(MPU) recognizes which key is depressed and executes key’s specific operation.
The scanning signals are also used for digit indicator signals for display tube as well.
The scanning signal from U26 –Y0 scans control lines KR0-KR4 and they are applied to
U17(MPU) as control signals.
According to the status of control signals, U17(MPU) executes specific operation.

3.2.3. display circuit
Display signals are applied to the display circuit board via J4..
The display signals for digit indication are also used for key scan signals which are decoded
At U25,U26(VHC138). The decoded signals from U25,U26 are amplified at U23,U24(driver:uPA80C)
and applied to the display tube on display circuit board.
The display signals for segment indication are output from port of CPU(P150-P157,P76,P77).
They are amplified at U22,U23 (driver:uPA80C) and applied to the display tube on display circuit
board.

3.2.4. printer drive circuit
Printer drive circuit consists of CPU(U17),U11,U12 and U9,U10 (driver), U13 (comparator)
Usually, P142 outputs “L” level. When one of department key is depressed, CPU outputs printer
power
Signal “H”(PR_PWR) from output port P142 of U17. Q3and Q4 turn ON. Thus the thermal head
On the printer mechanism is activated.
Serial print data input from “PR_DAT” is transferred to the shift register synchronously with the
Clock ”PR_CLK”, then stored in the latch register at the timing of the latch ”PR_/LA” signal.
The heat elements which correspond to the latched print data are activated while each gate is on.
The gates are on while each head activation signal (DST1 –DST4) is low.
3.2.5. Comparator circuit
The thermal head has a thermistor for detect the head temperature.
The level of the “TH_IN” is changed according to head temperature.
When head is heated too high temperature, the output level of comparator goes to “H” level.
Thus thermal head will be non-activity.
This status is released when the head become cool.

3.2.6 Paper near end sensor circuit
This circuit detects paper near end of receipt and journal individually.
The sensor is consist of a LED and a photo transistor.
It attached under the bottom base. There are two windows in order to sense the roll paper,
The light from LED reflect at the paper and be returned to the photo transistor.
Thus sensor output level become “H”(about 4V)
If paper roll slip out from holder, the light from LED cannot reflect, so the photo transistor
cannot receive the return light. Thus sensor output level become “L”(about 0.3V)
There is transistor on the CPU board in order to amplify the inputted signal.
So the inputted signal is not stable, that Q7,Q8 amplify the signal to “0V” or “5V”.
If paper roll slip out from holder, JNEND or RNEND will become to 5V.
When paper roll is on the holder, JNEND or RNEND is “0V”.
R72,R73 limit the current to supply to LED.

After PF_I0,PF_I1 set to “L” level, the signal PF_PH1,PF_PH2 are sequentially changed
for to feed the receipt paper. Similarly after JF_I0,JF_I1 set to “L” level, the signal JF_PH1,
JF_PH2 are sequentially changed for to feed the journal paper.

3.2.8 cutter motor drive circuit
Cutter unit have a motor and sensor switch(CUT_S).
“CUT A” is used as motor ON signal.
“CUT B” is used as motor brake signal.
When receipt is issued, “CUT A” becomes to “H” then cutter motor begin to cut the receipt paper.
Sensor switch detects the cutter position. After motor begin to cut the paper, switch becomes ON
(CUT_S=”L”) until cutting is complet. When “CUT_S” goes to “H”, the machine brakes the cutter
motor
by make “CUT_B” to “H”. The brake time is about 100msec.

3.2.9. Battery charge circuit
When the power is turn on, D12 and D13 turn on, thus +5V is applied to VBB line and
Recharge current is applied to the rechargeable battery via R31.
When the power is turned off, D12 and D13 turned off, thus battery output is applied to VBB.
When the power is turned off, battery output backs up the memory contents of RAM chip and
CPU internal RAM.

4 Trouble shooting
Phenomenon condition Considerable cause Check point/method Remedy
AC power is not supplied
AC power is not applied to
switching power supply.
Is AC power plug connected to outlet?
Is outlet voltage normal?
Is fuse (primary side of switching
Power supply?
Is 24V output from secondary side of
switching power supply?
Connect the plug to outlet.
Replace the fuse
Replace the switching power supply.
Is DC power voltage
normal?
+24V is not generated
+5V is not generated.
Does collector of PQ1 output oscillation
wave ?
Is PD11 defect?
Replace PQ1
Replace PD11
Replace converter transformer.
Crystal is not oscillating. Check wave form pin 20 and
Pin 22 of U17(frequency 20MHz)
Replace crystal(x1)
Replace U17
Machine
doesn’t work
at all
Printer doesn’t work
after power on
The levels of PF lines don’t
become “H”
Is D20 defect?
Are
Replace D20
Replace U27 and U33
Date/time
data fails.
Date doesn’t
increment.
Date /time data
doesn’t increment
correctly
Crystal(x2:32.768kHz) is
not oscillating properly.
Check wave form of pin 17 and pin 18 of
U17(frequency:32.768kHz)
Replace crystal(X2)
Buzzer
doesn’t sound
Trouble in buzzer circuit. When pin 8(P146)of U17 output “H”,
buzzer is driven.
Is Q1 defect?.
Replace the buzzer.
Replace Q1
Drawer is not
opened
Drawer solenoid
doesn’t operate.
Trouble in drawer circuit When pin 29(P145)of U17 output “H”,
drawer solenoid is driven.
Is Q6 defect?.
Replace Q6
Abnormal
print out
Printed character is
Not desired.
The level of timing signal is
not stable.
Printer is defect.
Is the signal level of pin 1(U13) stable? Replace U13

CONDITION CONSIDERABLE
CAUSE
CHECK POINT/
METHOD
REMEDY
Is the head unit over heat? When the head is over heated, printing is
stop.
Wait for head becomes cool. Printer
doesn’t work
at all
Printer motor doesn’t
rotate
Stepping signal does not
generated.
Is the stepping signal output from
P13X(U17)?
Is the stepping signal output from U9 or
U10?
Replace U17
Replace U9 or U10
Printer feed
the paper
without
printing
Printer motor does
work correctly
DC power for print head
unit is not output
When pin12(P142) of U17 outputs “H” ,
the head become active.
Replace Q3,Q4.
The FPC for CPU and FD
units connection is broken
Check conduction of FPC. Replace FPC
Display voltage(-30v) is not
generated
Is PD13 defect? Replace PD13
Replace converter transformer
Filament voltage (VF1,VF2)
is not generated.
Check the voltage between VF1 and
VF2(tolerance3.46Vrms)
Replace converter transformer
Center tap voltage of
filament is not correct.
Is the cathode voltage of PD14-23.5V? Replace PD14.
Display doesn’t light
Display tube is broken. Is the display tube cracked? Replace the display tube
Abnormal
display
Some ghost are
displayed.
Cut off voltage is generate
from PD21
Is cathode voltage of PD14 –23.5V? Replace PD14
Specific digit
is not lit
correctly
Key input correct Trouble in FD driver. Check the condition of the FPC Replace FPC
Replace U23,U24
Specific
segment is
not lit
correctly
Display data and time
data are correct.
Trouble in segment drive. Check the condition of the FPC. Replace FPC
Replace U22
2 key are depressed
together
Check whethe r any key keeps depressing. Replace key board unit.
Control mode is lock
position
When control lock is released, lock signal
is applied to KR lines(KR0-KR4)
Replace D10
Check conduction of the control key.
