Items 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.

Is the cause cleared by replacing the
thermal head?
Thermal head PCB Unit
YES
Finish.
Motors

Remove the drive PCB Unit CN5 and
follow the procedure

. Is the voltage
+24V?
YES
At the CN5 bundled wire or motors
+24V produces a short-circuit to GND.
Regulated power supply

Measure the voltage between the regulated
power supply, +S (+24) and -S(GND)
with the tester. Is it +24V?
NO
Follow the procedure

YES
Finish.
Main PCB Unit
NO
Replace the main PCB Unit.
Lamp

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.
Measure the voltage between L and N of the
regulated power supply with the tester. If it is
