Procedures Cause/Detective section Items to be checked Result Countermeasure
1 Is the feed tray properly attached? NO Properly attach the feed tray.
2
Does the horizontal registration motor
rotate when checked using HELP-015
YES Follow the procedure 7.
3 Fuse
Is the fuse(F1) of the drive PCB
unit normal?
NO Replace the fuse.
4
Horizontal registration
motor
Measure the voltage between CN6-
8 and CN6-9 of the drive PCB unit
when the horizontal registration
motor is activated using HELP-015.
Is it +24V or -24V?
YES
Check the wiring harness. If
there is no problem, replace the
horizontal registration motor.
5 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.
6
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.
7
Do the horizontal registration
encoder sensor and the horizontal
registration center sensor work
properly when checked using
HELP-015?
NO
Follow the procedure 8 when the
horizontal registration encoder
sensor is defective.
Follow the procedure 9 when
the horizontal registration center
sensor is defective.
8
Horizontal registration
encoder sensor
Measure the voltage with a tester
when turning the horizontal
registration encoder sensor on and
off. Is it normal?
NO Replace the horizontal
registration encoder sensor.
Main PCB unit YES
Check the wiring harness. If there
is no problem, replace the main
PCB unit.
9
Horizontal registration
center sensor
Measure the voltage with a tester
when turning the horizontal
registration center sensor on and
off. Is it normal?
NO Replace the horizontal
registration center sensor.
Main PCB unit YES
Check the wiring harness. If there
is no problem, replace the main
PCB unit.

1
Are all the wiring harnesses
of the main PCB unit securely
connected?
NO Securely connect all the
connectors of the main PCB unit.
Main PCB unit YES Replace the main PCB unit.
