1 NO Proceed to procedure 5.
Motor PCB unit
2 YES Finish.
Main PCB unit NO Replace main PCB unit.
Drum interferes with body. 3 YES Eliminate interference.
Drive system gear broken
4 YES Check if drive system gear is
or blocked with foreign broken or blocked with foreign
matter. matter and remove cause.
Regulated power supply

Does drum rotate?
Is trouble cleared by replacing motor
PCB unit?
Does main motor rotate without drum?
Does main motor rotate without the
driving timing belt?
Measure the voltage between the regulated
power supply, +S (+24) and -S(GND)
with the tester. Is it +24V?

CountermeasureItems to be checked
Wire or timing belt is cut
or removed.
1
Are the optical system driving wire and
timing belt attached properly?
NO Attach the wire and timing belt properly.
There is a foreign object
on the optical system
moving way.
2
Is the rail clean?Does the optical sys-
tem move smoothly when the optical
system driving timing pulley is rotated
manually?
NO
Check that there is no foreign object on
the rail and that nothing contacts the
optical system.
6
Is the cause cleared by replacing the
thermal head?
Thermal head PCB Unit YES Finish.
Motors
7
Remove the drive PCB Unit CN5 and
follow the procedure
3
. Is the voltage
+24V?
YES
At the CN5 bundled wire or motors
+24V produces a short-circuit to GND.
Regulated power supply
3
Measure the voltage between the regulated
power supply, +S (+24) and -S(GND)
with the tester. Is it +24V?
NO
Follow the procedure
4
.
YES
Drive PCB Unit
4
Is the cause cleared by replacing the
drive PCB Unit?
YES Finish.
Main PCB Unit NO Replace the main PCB Unit.
Lamp
5
Is the cause cleared by replacing the
lamp?
YES Finish.
Inverter PCB Unit NO Replace the inverter PCB Unit.
Measure the voltage between L and N of the
regulated power supply with the tester. If it is
100V, replace the regulated power supply.
