Procedures Cause/Detective section Items to be checked
Result Countermeasure
1
Fuse
Is the fuse (F7) of the relay PCB
unit normal?
NO Replace the fuse.
YES Follow the procedure 2.
2
Thermal head
Remove the all connectors of the
thermal head. Measure the voltage
between CN10-1 (+) and CN10-
14 (-) of the relay PCB unit with a
tester when the thermal head power
is on using HELP-008. Is it +24V?
YES
Check the wiring harness. If
there is no problem, replace the
thermal head.
NO
Follow the procedure 3.
3
24V power supply
Measure the voltage between
CN51-5 (+24) and CN51-1 (GND) of
the 24V power supply with a tester.
Is it +24V?
NO
Measure the voltage between
CN1-1 and CN1-3 of the 24V
power supply with a tester. If it is
AC100V, replace the 24V power
supply.
YES Follow the procedure 4.
4
Relay PCB unit
Does replacing the relay PCB unit
solve the problem?
YES Finish
5
Drive PCB unit
Does replacing the drive PCB unit
solve the problem?
YES Finish
Main PCB unit
NO Replace the main PCB unit.
Procedures Cause/Detective section Items to be checked
Result Countermeasure
1
Does the thermal head up/down motor
rotate when checked using HELP-008?
YES Follow the procedure 6.
2
Fuse
Is the fuse of the drive PCB unit normal?
NO Replace the fuse.
3
Thermal head up/down
motor
Measure the voltage between CN3-
25 and CN3-26 of the drive PCB
unit with a tester when the thermal
head up/down motor is activated
using HELP-008. Is it +24V?
YES
Check the wiring harness. If
there is no problem, replace the
thermal head up/down motor.
4
24V power supply
Measure the voltage between
CN51-5 (+24) and CN51-1(GND) of
the 24V power supply with a tester.
Is it +24V?
NO
Measure the voltage between CN1-1
and CN1-3 of the 24V power supply
with a tester. If it is AC100V, replace
the 24V power supply.
5
Drive PCB unit
Does replacing the drive PCB unit
solve the problem?
YES Finish
Main PCB unit
NO
Check the connector and bundled
wire between CN1 of the drive PCB
unit and CN19 of the main PCB unit.
If OK, replace the main PCB unit.
6
Thermal head position
sensor
Does the thermal head position
sensor work properly when checked
using HELP-008?
NO
Replace the thermal head
position sensor.
