1
Does the clamp motor turn when it is
checked using HELP-014?
YES Follow the procedure
6
.
Vertical registration motor 3
Using a tester, measure the voltage
between CN3-18 and CN6-19 when the
vertical registration motor is activated
using HELP-014. Is it +24V?
YES
Check the wiring harness. If there is no
problem, replace the vertical registration
motor.

Does replacing the drive PCB unit solve
the problem?
YES Finish.
Main PCB unit NO
NO
Check the connector and bundled wire
between the drive PCB unit CN1 and
the main PCB CN19. If OK, replace the
main PCB unit.
Main PCB unit
Vertical registration
encoder sensor
7
Turn the vertical registration encoder
sensor on and off, and use a tester to
measure voltage. Is voltage normal?
Turn the vertical registration center
sensor on and off, and use a tester to
measure voltage. Is voltage normal?
NO
Replace the vertical registration encoder
sensor.
Check the wiring harness. If there is
no problem, replace the main PCB.
YES
Main PCB unit
Vertical registration center
sensor
NO
Replace the vertical registration center
sensor.
Check the wiring harness. If there is
no problem, replace the main PCB.
YES
8
24V power supply
4
Measure the voltage between CN2-5
and CN2-1 of the 24V power with the
tester. Is the v24V?
NO
Measure the voltage between CN1-1 and
CN1-3 of the 24V power with the tester.
If it is AC100V, replace the 24V power.
Fuse Is the fuse of the drive PCB normal? Replace the fuse.
2
NO
Check with the HELP-014.
Are the vertical registration encoder
sensor and the vertical registration
center sensor normal?
Follow the procedure
7
when the vertical
registration encoder sensor is defective.
Follow the procedure
8
when the vertical
registration center sensor is defective.
