Cause/Detective section Procedures Items to be checked Result Countermeasure
1
Does contact pressure motor turn when
it is checked using HELP02*?
YES Follow the procedure 5.
Press motor 2
Using a tester, measure the voltage
between CN12-8 (+) and CN12-9 (GND)
when the press motor is activated using
HELP02*. Is it +24V?
YES
Check the bundled wire. If OK, replace
the press motor.
Regulated power supply
3
Drive PCB unit
4
Does replacing the drive PCB unit solve
the problem?
YES Finish.
Main PCB NO
Check the connector and bundled wire
between the drive PCB unit CN1 and
the main PCB CN3. If OK, replace the
main PCB unit.
Pressure encoder sensor 5
Turn the pressure encoder sensor on
and off, and use a tester to measure
voltage. Is voltage normal?
NO Replace t pressure encoder sensor.
Measure the voltage between the regulated
power supply, +S (+24) and -S(GND)
with the tester. Is it +24V?
NO
Measure the voltage between L and N of
the regulated power supply with the tester.
If it is 100V, replace the regulated power
supply.
